Juana is interested in estimating how long it takes students at her school to complete a maze she designed. She takes a random sample of 4 students and records how long it takes each of them to complete the maze. They work separately from each other, so Juana is willing to assume independence.

In 35 minutes, Suki’s car went 25 miles. If she continues at the same rate, how long will it take her to drive 90 miles?
Answer:
126 minutes or 2 hours, 6 minutes
Step-by-step explanation:
D=TR
25 miles= r times 35 minutes
r = 25 miles divided by 35 minutes = 5/7 miles/minute
90 miles = (5/7 miles/minute) times t
t=90 miles * (7/5 minutes/mile) = 126 minutes or 2 hours, 6 minutes
angle sum theorem y=?
Answer:
y + x + 90°=180°( sum of triangle=180°/Angeles of a triangle are supplementary)
y + x=180°-90°
there for x=y (Given by the theorem) OR two opposite angles of a triangle are equally
x+x= 90°/y+y=90° Note: Since y=x then sub y by x or y instead of the same equition (y=x)
x+x/y+y=90°
2x=90°
x=45°
or
x+y=90°
45+y=90°
y=90°-45°
y=45°

midpoint E(-7,8) and F(-9,3)
Answer:
(-8, 11/2)
Step-by-step explanation:
1. The midpoint between two points can be found by averaging the x-values of both points and the y-values of both points. For example, if you had the points (x, y) and (m, n), then the midpoint would be ([tex]\frac{x+m}{2}[/tex], [tex]\frac{y+n}{2}[/tex])
2. Calculate your midpoint. In this specific case your x-value would be (-7+-9)/2 and your y-value would be (8+3)/2, or (-8, 11/2)
The equation of a line is y – 13 = 6x What is the y-intercept of the line?
Answer:
Equation of line y-3 = 6x
This equation can be written as
[tex] \rm 6x - y + 13 = 0[/tex]
We are asked to find y-intercept of the line .
Using Slope Intercept Formula
[tex]\qquad \bf \longrightarrow \: y = mx \: + b \: - - - - - (i)[/tex]
Where
m is the slope of line
b is the y-Intercept
[tex]\qquad \sf \longrightarrow \rm 6x - y + 13 = 0 \\ \\ \\ \qquad \sf \longrightarrow \: y \: = 6x + 13 - - - - - - (ii)[/tex]
On comparing equation (i) and (ii) we obtain
[tex]\qquad \sf \longrightarrow \: b \: = 13[/tex]
Therefore,
y-intercept of the line is 13.The y-intercept of the line, given that the line has an equation of y - 13 = 6x is 13
How to determine the y-intercept?The equation of a straight line is given as follow:
y = mx + c
Where
m is the slope c is the intercept on the y-axisThe following data were obtained from the question:
Equation of line: y - 13 = 6xy-intercept =?The y-intercept of the line having an equation of y - 13 = 6x can be obtained as follow:
y - 13 = 6x
Make y the subject
y = 6x + 13
Comparing y = 6x + 13 with y = mx + c, we have the intercept as 13
Thus, we can conclude that the y-intercept of the line is 13

Hi that symbol is for 90 degrees , that means when u add x + 53 equals to 90 degrees . so the answer is 37 degreesTwo trains, traveling towards each other, left from two stations that are 900
kilometers apart, at 7:00 a.m.. If the rate of the first train is 70 km/h and the
rate of the second train is 90 km/h, at what time will they pass each other
Answer:
1 12:37:pm
Step-by-step explanation:
1)
let x = time that they will pass each other
distance travelled = speed * time
distance of train 1 = 70*x
distance of train 2= 90*x
distance travelled is equal to 900km
70x + 90x = 900
160x = 900
x=5.625
convert into hrs, minutes and seconds
5.625 hrs is equal to 5 hrs, 37 mins, and 30 seconds
add this time to 7:00 am to get the answer
