Answer:
x=5
Step-by-step explanation:
36x-20=160
first, find the value of x
add 20 from both sides
36x-20=160
+20 +20
36x=180
then, divide 36 from both sides to get x by itself
36x/36=140/36
x=5
now, plug x into the equation to check your work
36(5)-20=160
multiply 36 and 5
180-20=160
subtract 20 from 180
180-20=160

The table and the graph each show a different relationship between the same two variables, x and y: (Both of the tables are shown below) How much more would the value of y be in the table, than its value on the graph, when x = 11? (1 point) 55 95 100 215
Answer:
55
Step-by-step explanation:
Table - 450 + 540 = 990
Graph - 850 + 85 = 935
On the table eleven would equal 990.
On the graph eleven would equal 935.
990 - 935 = 55

Evaluate: x(y – 5) for x = 2 and y = 7
Answer:
Replace all occurrences of x x in x−y=5 x - y = 5 with 7−y 7 - y . x=7−y x = 7 - y. (7−y)−y=5 ( 7 - y ) - y = 5. Subtract y y from −y - y . x=7−y x = 7 - y. 7−2y=5 7

Factor the following quadratic function:
-
y = 7x2
- 48x - 7
How do I do it
Answer:
(7x + 1)(x - 7).
Step-by-step explanation:
y = 7x^2 - 48x - 7
Use the 'ac' method:
7 * 7 = 49
Now we need 2 numbers whose product is 49 and whose sum is the 'middle' number -48.
They are -49 and 1,
Now we write the function as:
7x^2 - 49x + 1x - 7
= 7x((x - 7) + 1(x - 7) (x - 7) is common so we have
(7x + 1)(x - 7).
The scores on a test are normally distributed with a mean of 70 and a standard deviation of 14. Find the score that is two and one half standard deviations below the mean
Answer:
35
Step-by-step explanation:
We solve the above question using z score formula
z = (x-μ)/σ, where
x is the raw score = ?
μ is the population mean = 70
σ is the population standard deviation = 14
We were given the z score in the question as: Two and one half standard deviations below the mean
Hence:
= μ - zσ
= 70 - 2.5(14)
= 70 - 35
= 35
The score that is two and one half standard deviations below the mean is 35

Answer:
B
Step-by-step explanation:
The answer is B. If you look at the graph at its current state you can see that the lines are parallel to each other. This is important because it says TWO lines are being translated and rotated. So whatever happens to one line happens to the other line which proves they were always parallel to each other.

What is graph?
Graph is a mathematical representation of a network and it describes the relationship between lines and points.
As, per the graph we can see that the range for y starts from negative infinity but it only exceeds upto +4.
Hence, the range is -∞ < y ≤ 4.

suppose X and Y are independent random variables, both with normal distributions. If X has a mean of 45 with a standard deviation of 4 and Y has a mean of 35 with a standard deviation of 3, what is the probability that a randomly generated value of X is greater than a randomly generated value of Y
Answer:
0.9772 = 97.72% probability that a randomly generated value of X is greater than a randomly generated value of Y
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question:
[tex]\mu_X = 45, \sigma_X = 4, \mu_Y = 35, \sigma_Y = 3[/tex]
What is the probability that a randomly generated value of X is greater than a randomly generated value of Y
This means that the subtraction of X by Y has to be positive.
When we subtract two normal variables, the mean is the subtraction of their means, and the standard deviation is the square root of the sum of their variances. So
[tex]\mu = \mu_X - \mu_Y = 45 - 35 = 0[/tex]
[tex]\sigma = \sqrt{\sigma_X^2+\sigma_Y^2} = \sqrt{25} = 5[/tex]
We want to find P(X > 0), that is, 1 subtracted by the pvalue of Z when X = 0. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{0 - 10}{5}[/tex]
[tex]Z = -2[/tex]
[tex]Z = -2[/tex] has a pvalue of 0.0228
1 - 0.0228 = 0.9772
0.9772 = 97.72% probability that a randomly generated value of X is greater than a randomly generated value of Y

In a woodworking class, you need to make five triangles out of plywood. Each triangle has a height of 6 inches and a base of 14 inches. Which equation can you use to solve for the total amount of plywood you will need?
Answer:
210 in²Step-by-step explanation:
Use the formula for area:
A = 1/2bhEach triangle will have the area of:
A = 1/2*6*14 = 42 in²Total amount of plywood will be:
42*5 = 210 in²Find the roots of h(t) = (139kt)^2 − 69t + 80

the larger root is:
The answers will consist of algebraic expressions containing the parameter k.
What positive value of k will result in exactly one real root?
K = ?
Step-by-step explanation:
Given
[tex]h(t)=(139kt)^2-69t+80[/tex]
For roots [tex]h(t)=0[/tex]
[tex](139kt)^2-69t+80=0\\t=\dfrac{69\pm\sqrt{(-69)^2-4\times (139k)^2(80)}}{2\times 139}\\[/tex]
[tex]t=\dfrac{69\pm\sqrt{4761-6182720k^2}}{278}[/tex]
Larger root: [tex]t=\dfrac{69+\sqrt{4761-6182720k^2}}{278}[/tex]
smaller root: [tex]t=\dfrac{69-\sqrt{4761-6182720k^2}}{278}[/tex]
For exactly one root D=0
i.e. [tex]4761-6182720k^2=0\\\\k=\dfrac{69}{139\times 4\times 2\times \sqrt{5}}\\k=0.0277[/tex]

Step-by-step explanation:
From the question, we are given the following parameters
Amount borrowed (principal)=$3800
Time=3 months =1/4 years

Required
Interest paid by the man
Using the simple interest formula;
SI= Principal*Rate*Time/100
SI=3800*8.5*0.25/100
SI=38*8.5*0.25
SI=$80.75
