Context: You and your friends go to the state fair. It costs $6 to get into the fair and $2 each time you go on a ride. Where do you see the y-intercept in the table and in the equation?
Answer:
see below
Step-by-step explanation:
The y intercept is when x =0
The equation is y =2x+6
The equation is in the form y = mx+b. It is the constant added to the equation.
In the table it is the y value when x =0

Find the measure of /_2.
45°
120°
30°
90°
Answer:
45°
as triangle is right angled and inside a quater of a square it is isosceles
so both 2 and 3 are 45°
Find the missing side of the triangle. Round your answers to the nearest tenth if necessary.
9 ft
2.5 ft
9.4 ft
7.5 ft
Given:
In a right angle triangle, the measures of two legs are 5 ft and 5.6 ft. The measure of the hypotenuse is x.
To find:
The value of x.
Solution:
Pythagoras theorem: In a right angle triangle,
[tex](Hypotenuse)^2=(Base)^2+(Perpendicular)^2[/tex]
Using Pythagoras theorem, we get
[tex](x)^2=(5)^2+(5.6)^2[/tex]
[tex]x^2=25+31.36[/tex]
[tex]x^2=56.36[/tex]
Taking square root on both sides, we get
[tex]x=\sqrt{56.36}[/tex]
[tex]x=7.50733[/tex]
[tex]x\approx 7.5[/tex]
The measure of missing side is 7.5 ft. Therefore, the correct option is D.
A man is now 3 times as old as his son. In 10 years time, the sum of their ages will be 76.
How old was the man when his son was born?
Answer:
28
Step-by-step explanation:
A man is now 3 times as old as his son.
m = 3s
In 10 years time, the sum of their ages will be 76
(m + 10) + (s + 10) = 76
Subsitute for m = 3s
(3s + 10) + (s + 10) = 76
4s + 20 = 76
4s = 56
s = 14
m = 3s = 14 * 3
m = 42
------------------------
How old was the man when his son was born?
m - s = 42 - 14
m - s = 28
The graph compares the scores earned by 100 students on a pre-test and a post-test.
Two box and whisker plots showing Pre-Test and Post-Test scores on a number line from 0 to 100. The upper plot represents the pre-test scores. For this upper plot, the minimum number is 0, the maximum number is 78, the right side of the box is 60, the left side of the box is 16, and the bar in the box is at 30. The lower plot represents the post-test scores. For this lower plot, the minimum number is 4, the maximum number is 100, the right side of the box is 83, the left side of the box is 30, and the bar in the box is at 45.
About how many more students scored greater than 30% on the post-test than on the pre-test?
15
Answer:
25 more studentsStep-by-step explanation:
30% mark represents:
50% on pre-test and 25% on post test.So
50% of 100 = 50 students scored greater than 30%75% of 100 = 75 students scored greater than 30%.The difference is:
75 - 50 = 25 studentsAnswer:
25 students

Step-by-step explanation: Please give brainliest.
Answer: -25 degrees Celsius
=========================================================
Explanation:
Draw a vertical number line. Plot -20 on it. Then move 5 units down to arrive at -25. Think of it as a thermometer where the temperature can be measured below 0 degrees, or you could think of it like floors of a building. Negative values would be basement floors.
The diagram below describes what's going on when we compute -20-5 = -25.

The circle is divided into 5 sections. The probability that the needle lands on a particular color is equally likely.
So,
[tex]P(red) = \frac{1}{5}\\\\P(green) = \frac{1}{5}\\\\[/tex]
Probability of not blue = 1 - Probability of blue
[tex]= 1 - P(blue)\\\\=1 - \frac{1}{5}\\\\= \frac{4}{5}[/tex]

The lenten on a map states that 1 inch is 40 miles. If you measure 5 inches on the map, how many miles would the actual distance be?
===============================================
Work Shown:
(1 inch)/(40 miles) = (5 inches)/(x miles)
1/40 = 5/x
1*x = 40*5 .... cross multiply
x = 200 miles
------------
We could also look at it like this:
1 inch = 40 miles
5*(1 inch) = 5*(40 miles) .... multiply both sides by 5
5 inches = 200 miles

Answer:
-30a⁵b + 12a⁴b² + 16a³b² - 4a²b⁴ - 2ab³
Step-by-step explanation:
( - 6a³b + 2ab²)( 5a² - 2ab² b)
multiply the second parantheses by each term from the first parantheses.
-6a³b×(5a²- 2ab²b -b)+2ab×(5a² -2ab²b-b)
-6a³b× (5a² - 2ab² b) +2ab × (5a² - 2ab² b)
-30 a⁵b + 12a⁴b² + 6a³b²+ 10a³b² - 4a²b⁴ - 2ab

I If the game with 3 hits is considered to be recorded in error, it might be removed from the data set. If that happens a. What happens to the mean of the data set? b. What happens to the median of the data set? plot data- 2(0) 3(1) 4(0) 5(0) 6(0) 7(2) 8(4) 9(5) 10(4) 11(4) 12(0) 13(0) .please help
Answer:
If the game with 3 hits is ignored the data becomes:
7, 7, 8, 8, 8, 8, 9, 9, 9, 9, 9, 10, 10, 10, 10, 11, 11, 11, 11a) The mean will increase.
With 3:
(3 + 7*2 + 8*4 + 9*5 + 10*4 + 11*4)/20 = 8.9Without 3:
(7*2 + 8*4 + 9*5 + 10*4 + 11*4)/19 = 9.21b) The median will remain as is.
With 3 and without the median is same = 9
