What specific measure of a geometric figure is shown in the image?
Answer:C, A 70 angle
Step-by-step explanation:
Answer:
The specific measure of a geometric figure is shown in the image is a 70° angle.
Thus, option 'A' is correct.
Step-by-step explanation:
We know that protectors normally have:
two sets of numbers going in opposite directions.From the figure, it is clear that:
The center point of the protector lies on the vertex of the angle.The zero mark is the bottom edge of the protractor.It is clear that the other ray tends to cross the protractor at the measure 70 degrees.
Therefore, the specific measure of a geometric figure is shown in the image is a 70° angle.
Thus, option 'A' is correct.
What is the slope of the line y=5?
Answer:
0
Step-by-step explanation:
if you slightly change the equation to better fit standard form (without actually changing its meaning) you get
y = 0x + 5
which means the slope is 0
Also, a shortcut:
Horizontal lines always have a 0 slope while vertical lines have an undefined slopeCarolyn drove from her home to school at 40 mph and was 10

Here are measurements (in millime- ters) of a critical dimension on an SRS of 16 of the more than 200 auto engine crankshafts produced in one day: 224.120 224.001 224.017 223.982 223.989 223.961 223.960 224.089 223.987 223.976 223.902 223.980 224.098 224.057 223.913 223.999 (a) Construct and interpret a 95% confidence interval for the process mean at the time these crankshafts were produced.
Answer:
(23.97, 24.03)
Step-by-step explanation:
Given the data:
224.120 224.001 224.017 223.982 223.989 223.961 223.960 224.089 223.987 223.976 223.902 223.980 224.098 224.057 223.913 223.999
Confidence interval = m ± Zcritical(s/√n)
n = sample size = 16
Zcritical at 95% = 1.96
Using calculator :
Sample mean, m = 224.0019
Standard deviation, s = 0.0618
Lower bound : 24.0019 - 1.96(0.0618/√16) = 23.971618
Upper bound : 24.0019 + 1.96(0.0618/√16) = 24.032182

Answer:
The rate of change of Function A is less than the rate of change of function B.
Other than that, everything else you put is correct.
Step-by-step explanation:
None.
Answer:
Option A, B and D are correct options.
Step-by-step explanation:
First we will find rate of change of function A and function B
Rate of Change of Function A
The formula used to calculate rate of change is: [tex]Rate\:of\:Change=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have x_1=1, y_1=5, x_2=2, y_2=7
Putting values in formula and finding rate of change
[tex]Rate\:of\:Change=\frac{y_2-y_1}{x_2-x_1}\\Rate\:of\:Change=\frac{7-5}{2-1}\\Rate\:of\:Change=\frac{2}{1}\\Rate\:of\:Change=2[/tex]
So, Rate of change of Function A = 2
Now, finding y-intercept.
y-intercept is found by putting x =0
Looking at the function, we can write the equation: y=2x+3
Now, put x =0
y=2(0)+3
y=3
So, when x =0, y=3
So, y-intercept is 3 for function A.
Rate of Change of Function A
The formula used to calculate rate of change is: [tex]Rate\:of\:Change=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have x_1=1, y_1=1, x_2=2, y_2=4
Putting values in formula and finding rate of change
[tex]Rate\:of\:Change=\frac{y_2-y_1}{x_2-x_1}\\Rate\:of\:Change=\frac{4-1}{2-1}\\Rate\:of\:Change=\frac{3}{1}\\Rate\:of\:Change=3[/tex]
So, Rate of change of Function B = 3
Now, finding y-intercept.
y-intercept is found by putting x =0
Looking at the graph, when x=0, y is -2
So, y-intercept is -2 for function B.
We get following answers:
Rate of change of Function A = 2
Rate of change of Function B = 3
y-intercept is 3 for function A.
y-intercept is -2 for function B.
So, The correct options are:
The rate of change of function A and B are positive
The rate of change of function A is less than the rate of change of function B. (Because 2 is less than 3)
The y-intercept of function A is positive, while y-intercept of function B is negative.
So, Option A, B and D are correct options.
Write the Linear Equation given:
1. Slope = 4; y-intercept = -5
2. Slope = 5; y-intercept = 3
3. Slope = -2; y-int; y-intercept = -8
4. Slope = 2; y-intercept = 2
5. Slope = -%; y-intercept = -2
6. Slope = /; y-intercept = 7
7. Slope = -3; y-intercept = ?
8. Slope = %; y-intercept = 10
9. Slope = -2; y-intercept = -1
10.Slope = -2; y-intercept = -3

Pedro’s car odometer measures the distance driven in kilometers. Pedro determines that, for every 810 kilometer he drives, he drives the equivalent distance of 510 mile. What is that ratio as a unit rate of kilometers to miles?
Answer:
The ratio of a unit rate of kilometers to miles of the distance measured by the odometer is 1 km : 0.63 miles.
Step-by-step explanation:
Given;
distance measured by odometer in kilometer, = 810 km
distance measured by odometer in miles, = 510 miles
The ratio of a unit rate of kilometers to miles of the distance measured by the odometer is calculated as;
[tex]d = \frac{810 \ km}{510 \ miles} \\\\d = \frac{810 \ km \ \times \ \frac{1}{810 \ km} }{510 \ miles \ \times \frac{1}{810 \ km} } \\\\d = \frac{1 \ km}{\frac{510}{810} \ miles } \\\\d = \frac{1 \ km}{\frac{17}{27} \ miles} \\\\d = 1 \ km : \frac{17}{27} \ miles\\\\d = 1 \ km : 0.63 \ miles[/tex]
Therefore, the ratio of a unit rate of kilometers to miles of the distance measured by the odometer is 1 km : 0.63 miles.
At first, you have 15 bottles of coke, and you drink 2 bottles each day. After a certain number of days, there are 3 bottles left. Write and solve an equation for, d, when there are 3 bottles left?
Answer:
After 6 days, 3 bottles will be left.
Step-by-step explanation:
Given that:
Number of bottles = 15
Number of bottles drank each day = 2
Let,
d be the number of days
y be the number of bottles left
y = 15 - 2d
Now,
We have to find the number of days when 3 bottles will be left.
Putting y=3
3 = 15 - 2d
2d = 15 - 3
2d = 12
Dividing both sides by 2
[tex]\frac{2d}{2}=\frac{12}{2}\\d=6[/tex]
Hence,
After 6 days, 3 bottles will be left.

Kyle is raising money for his school. He has $75 saved and needs to raise at least $150. He wrote part of an inequality to help him find the minimum amount of money needed to raise. Which inequality symbol can be used in the box to make this inequality correct?
≥
Answer: >_
Step-by-step explanation:
The symbol for inequality is represented as "≥".
Given data:
To find the minimum amount of money Kyle needs to raise, the inequality is determined as:
Kyle already has $75 saved, and he needs to raise at least $150.
Let's represent the minimum amount he needs to raise with the variable "x."
The inequality can be written as:
$75 + x ≥ $150
In this inequality, we are adding the amount Kyle has saved ($75) to the amount he needs to raise (x), and it should be greater than or equal to $150.
To indicate that the left side of the inequality should be greater than or equal to the right side, we use the symbol "≥" in the box.
Hence, the correct inequality symbol to make the inequality accurate is "≥".

In the first week of July a record 1120 people went to the local swimming pool in the second week 105 fewer people went to the pool then in the first week in the third week 135 more people went to the pool then in the second week in the first week 310 fewer people went to the pool then in the third week what is the percent decrease in the number of people who went to the pool over these four weeks
Answer:
25%
Step-by-step explanation:
The number of people who went to the local swimming pool in the;
first week = 1120
second week ( 105 fewer people) = 1120 - 105 = 1015
third week (135 more people) = 1015 + 135 = 1150
fourth week (310 fewer people|) = 1150 - 310 = 840
The percent decrease in the number of people who went to the pool over these four weeks
= (1120 - 840)/1120 * 100%
= 280/1120 * 100%
= 1/4 * 100%
= 25%
It means that the number of people who went to the local swimming pool over the 4 weeks decreased by 25%

An integer that represents the situation is [ ]?
Answer:
it's -10
Step-by-step explanation:
because in the question they says below the surface of the water
so I think it's right
The upward is taken as positive and the downward is taken as negative. Then the integer can be represented as negative 10.
What is a sign convention?Sign convention means the rule that is used when the sign is to be changed. It is applicable only when the equation is considered.
You dive 10 feet below the surface of the water.
Then the negative sign should be used because we considered the right side as positive and the left side as negative similarly upward is taken as positive and downward is taken as negative.
Then the integer can be represented as negative 10.

Marcus says that a store overcharged him on the price of the video game he bought. He thought that the price was marked of the original price, but it was really off the original price.
He misread the advertisement.
If the original price of the game was $48, what is the difference between the price that Marcus thought he should pay and the price that the store charged him?
Answer:
$14
Step-by-step explanation:
Since the original price of the game was $48 and the store wanted to sell it with 1/4 off the total price, we can say that (48) - (48 *1/4) = 36. Since marcus thought that he was buying the game for 1/4 of the original price, that would be 48 * 1/4 = 12.
The difference between 36 and 12 is 14, which would be the answer.
A warehouse contains ten printing machines, four of which are defective. A company selects five of the machines at random, thinking all are in working condition. The company repairs the defective ones at a cost of $20 each. In what interval would you expect the repair costs on these five machines in dollars to lie 75% of the time
Answer:
Step-by-step explanation:
There from ypergemetric distribution
mean number of defective in sample =n×m/N =5×4/10=2
and std deviation =sqrt(mn/N*(1-m/N)*(N-n)/(N-1))
=sqrt(5*4/10*(1-4/10)*(10-5)/(10-1))=0.816
from Tchebysheff's theorem ; 75% values fall within 2 standard deviation from mean
therefore interval in terms of defective
=2-2*0.816 ; 2+2*0.816 =0.367 ; 3.633
interval in terms of repair costs =20*0.367 ; 20*3.633 =$7.34 ; $ 72.66

Answer:
Answer:
Try this option, note: only calculation is performed, the last two question are missed.
Step-by-step explanation:
to calculate 'x':
the rule: m∠BAC+m∠ABC+m∠BCA=180°; if to substitute m∠BAC=4x+10,m∠ABC=12x-6,and m∠BCA=3x+5, then 4x+10+12x-6+3x+5=180°; ⇔ x=9.
to calculate m∠BAC; m∠ABC; m∠BCA:
m∠BAC=4x+10; ⇒ m∠BAC=36+10=46°;
m∠ABC=12x-6; ⇒ m∠ABC=108-6=102°;
and m∠BCA=3x+5; ⇒ m∠BCA=27+5=32°.
to calculate the angle 1 and 2:
the fule is: m∠1+m∠BAC=180° and m∠2+m∠ABC=180°.
Then m∠1=180-m∠BAC=180-46=134°;
m∠2=180-m∠ABC=180-102=78°.
