Y=3x+5
Answer:
y = -1/3 + 5
Step-by-step explanation:
you get the reciprocal of the slope in order to make a perpendicular copy
What is the slope of the line segment?
A graph is shown. The values on the x axis are 0, 1, 2, 3, 4, and 5. The values on the y axis are 0, 5, 10, 15, 20, and 25. A straight line joining the ordered pairs 0, 0 and 1, 5 and 2, 10 and 3, 15
5
1 over 5
negative 1 over 5
−5
Answer:
The slope is 5
Step-by-step explanation:
divide the change in y by the change in y
you can use two different points for example 1,5 and 3,15
the change in y between these points is 10, the change in x is 2
10/2=5
also since the values of x increase constantly by 1 and it's a continuous line (meaning the domain could be any number between 1 and 3 in this graph) you can calculate only the change in y and that will give you the slope

Cami is comparing the growth rates in the value of two items in a collection. the value of a necklace increases by 3.2% per year. the value of a ring increases by 0.33% per month.
1a) Write a function to represent the value of A of the necklace after t years, assuming the initial value of $1
1b) then write an equivalent function with a power of 12t
2a) Write a function to represent the value of B of the ring after t years with the power of 12t , assuming the initial value of $1
2b) then write an equivalent function with a power of t
so
1a) A= 1 (1+3.2/100)^t
A= $1.032
1b) ????? please help
2a) B=1 (1+0.33/100)^12t
B= $1.04
2b) ???????? please help
ty ty ty this momma is trying to help her kids and is a bit lost !
Problem 1, part (a)
t = number of years
A = value of the necklace after t years
3.2% = 3.2/100 = 0.032
If the necklace starts off being $1, then after t years, it will have this value
A = 1*(1 + 0.032)^t
A = 1.032^t
You were close, but forgot about the exponent t
------------------------------------
Problem 1, part (b)
Since t represents the number of years, this means 12t represents the number of months, because there are 12 months in a year.
The annual growth rate is 3.2%, which converts to 0.032
Divide this over 12 and we get the approximate value 0.032/12 = 0.00267
So we get this new equivalent function
A = 1*(1+0.00267)^(12t)
A = 1.00267^(12t)
=========================================================
Problem 2, part (a)
t = number of years
12t = number of months
The ring's value goes at a rate of 0.33% per month, which converts to the decimal form 0.0033
The value of the ring is
B = 1*(1 + 0.0033)^(12t)
B = 1.0033^(12t)
------------------------------------
Problem 2, part (b)
We'll take the reverse approach in what we did with part (b) of the previous problem. There we divided by 12 to go from an annual rate to a monthly rate.
We'll multiply by 12 to go from the monthly growth rate to the annual growth rate.
The monthly growth rate of 0.33% turns into the annual growth rate of 12*0.33% = 3.96%, and that turns into the decimal form 0.0396
So,
B = 1*(1+0.0396)^t
B = 1.0396^t
represents the value of the ring after t years.
A lumber company is making boards that are 2857.0 millimeters tall. If the boards are too long they must be trimmed, and if the boards are too short they cannot be used. A sample of 16 is made, and it is found that they have a mean of 2858.7 millimeters with a variance of 100.00. A level of significance of 0.05 will be used to determine if the boards are either too long or too short. Assume the population distribution is approximately normal. Is there sufficient evidence to support the claim that the boards are either too long or too short
Answer:
The test statistic 't' = 0.68 < 2.1314 at 0.05 level of significance
Null Hypothesis is accepted
There is no sufficient evidence to support the claim that the boards are either too long or too short
Step-by-step explanation:
Step(i):-
Mean of the Population (μ) = 2857.0 millimetres
size of the sample 'n' = 16
Mean of the sample (x⁻) = 2858.7 millimetres
The Variance of the sample (S²)= 100.00
Standard deviation of the sample (S) = √100 =10
Degrees of freedom = n-1 =16-1 =15
Level of significance =0.05
Tabulated value = [tex]t_{\frac{0.05}{2} , 15} = t_{0.025,15} = 2.1314[/tex]
Step(ii):-
Null Hypothesis :H₀ : There is no sufficient evidence to support the claim that the boards are either too long or too short
Alternative Hypothesis: H₁:There is sufficient evidence to support the claim that the boards are either too long or too short
Test statistic
[tex]t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }[/tex]
[tex]t = \frac{2858.7 -2857}{\frac{10}{\sqrt{16} } }[/tex]
t = 0.68
The calculated value = 0.68 < 2.1314 at 0.05 level of significance
Null Hypothesis is accepted
Final answer:-
There is no sufficient evidence to support the claim that the boards are either too long or too short
We choose a number from the set 1, 2, 3,..., 100 uniformly at random and denote this number by X. For each of the following choices decide whether the two events in question are independent or not.
a. A = {X is even), B-(X is divisible by 5}
b. C= (X has two digits), D = {X is divisible by 31}
c. E= {X is a prime), F = {X has a digit 5}
Answer:
(a) A and B are dependent.
(b) C and D are dependent.
(c) E and F are dependent.
Step-by-step explanation:
Two sets are said to be independent if the intersection of the two set is empty. That is the sets are disjoint.
Let's examine the situations to determine if they are independent or not.
(a) A = {2, 4, 6, . . . , 10, . . . , 20, . . .} and B = {5, 10, 15, . . . , 20, . . .}. Since A n B = {10, 20, . . .}, then the sets are dependent
(b) C = {10, 11, 12, . . . , 31, . . . , 62, . . . , 93, . . .} and D = {31, 62, 93}. Since C n D = {31, 62, 93}, then the sets are dependent.
(c) E = {5, 7, 11, . . .} and F = {5, 15, . . .}. Since E n F = {5}, then the set are dependent.
Thus
(a) A and B are dependent.
(b) C and D are dependent.
(c) E and F are dependent.

Answer:
Anthony needs to invest $99.33.
Step-by-step explanation:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Interest rate of 2.7% compounded quarterly.
This means that [tex]r = 0.027, n = 4[/tex].
How much would Anthony need to invest, to the nearest hundred dollars, for the value of the account to reach $130 in 10 years?
We have to find P for which: [tex]A = 130, t = 10[/tex]. So
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]130 = P(1 + \frac{0.027}{4})^{4*10}[/tex]
[tex]P = \frac{130}{(1 + \frac{0.027}{4})^{4*10}}[/tex]
[tex]P = 99.33[/tex]
Anthony needs to invest $99.33.

The value of your father’s car when bought was $30,000. If it loses 10% of its value every year, how long until the vehicle is only worth $20,000?
Answer:
6.7
Step-by-step explanation:
10% of 30000
10/100 x 30000
0.10 x 30000
=3000
In order to find how long you have to divide 20k with 3k
20000/3000 = 6.66666667
Round it up and you get 6.7
The sum of the measures of the angle in any triangle is 180 degrees. In triangle ABC, angles A and B have the same measure, while angle C is 42 degrees larger than each of the other two angles. Find the measure of angle C.
Answer:
88°
Step-by-step explanation:
we can say the two base angles are each x°
the vertex angle (∡C) is (42 + x)°
add them all and set equal to 180°
x + x + x + 42 = 180
3x + 42 = 180
3x = 138
x = 46
∡C = 46 + 42 = 88°
If angle C is 42 degrees larger than each of the other two angles. then measure of angle c is 88 degrees.
What is Angle Sum property?The sum of angles of a triangle are 180 degrees.
Given that,
The sum of the measures of the angle in any triangle is 180 degrees. In triangle ABC, angles A and B have the same measure, while angle C is 42 degrees larger than each of the other two angles. we can say the two base angles are each x°
the vertex angle (∡C) is (42 + x)°
add them all and set equal to 180°
x + x + x + 42 = 180(By angle sum property)
3x + 42 = 180
Shift 42 to RHS
3x = 180-42
3x = 138
Divide both sides by 3.
x = 46
∡C = 46 + 42 = 88°
Therefore angle C is 88°.

An educational psychologist wishes to know the mean number of words a third grader can read per minute. She wants to make an estimate at the 85% level of confidence. For a sample of 295 third graders, the mean words per minute read was 26.9. Assume a population standard deviation of 2.7. Construct the confidence interval for the mean number of words a third grader can read per minute. Round your answers to one decimal place
Answer:
85% level of the confidence interval is
(26.337, 26.662)
Step-by-step explanation:
Explanation:-
Given the size of the sample 'n' = 295
Mean of the sample x⁻ = 26.5
The Standard deviation of the Population = 2.7
85% level of the confidence interval is determined by
[tex](x^{-} - Z_{0.15} \frac{S.D}{\sqrt{n} } , x^{-} + Z_{0.15} \frac{S.D}{\sqrt{n} })[/tex]
Critical value Z₀.₁₅ = 1.036

A local pizza restaurant delivery time has a uniform distribution over 10 to 75 minutes. What is the probability that the pizza delivery time is more than 30 minutes on a given day
Answer:
The probability that the pizza delivery takes more than 30 minutes is 61.53%.
Step-by-step explanation:
To determine the percentage of probability that the pizza will take more than 30 minutes to be delivered, knowing that the delivery delay time is evenly distributed between 10 and 75 minutes, the following calculation must be performed:
75 - 10 = 65
100/65 = 1.53
30 - 10 = 20
65 - 20 = 40
40 x 1.53 = 61.53
Therefore, the probability that the pizza delivery takes more than 30 minutes is 61.53%.
Answer:
0.6923
Step-by-step explanation:
we have to find P(X>45)
uniform distribution formula is P(X>A) = (b-A)/(b-a)
we have A = 30, a = 10 and b =75
P(X>45) = (75-30)/(75-10) = 45/65
P(X>45) = 0.6923

(-3,-5);m=-2/5
A. Y+5=-2/5(x+3)
B. Y+5=(-2/5)x-3
C. Y-5=-2/5(x+3)
D. Y-5=-2/5(x-3
Answer:
We conclude that an equation in the point-slope form will be:
y+5 = -2/5 (x+3)
Hence, option A is true.
Step-by-step explanation:
We know that the point-slope form of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
Given
point (-3, -5)slope m = -2/5substituting the values m = -2/5 and the point (-3, -5) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
y - (-5) = -2/5 (x-(-3))
y+5 = -2/5 (x+3)
Therefore, we conclude that an equation in the point-slope form will be:
y+5 = -2/5 (x+3)
Hence, option A is true.
