Answer:

0 ≤ t < 52.5 minutes

Step-by-step explanation:

Riko will be behind Yuto until her distance traveled matches his. That is, she will be behind for ...

0.35t < 5.25 +0.25t

0.10t < 5.25

t < 52.5

Riko will be behind Yuto on the interval 0 ≤ t < 52.5 minutes.

Additional comment

distance = speed × time

Here, time is measured from when Riko starts riding. In addition to the 5.25 miles that Yuto has already gone, his distance will be the product of his speed (0.25 mi/min) and the travel time (t min). Then Yuto's total distance is 5.25+0.25t miles. The speed×time product is also used to find Riko's distance traveled. In her case, it is 0.35t miles.

Find the slope of the line that passes through the points (2.1) and (-1.-1).

sp2606 [1]

Answer: The slope is $\frac{2}{3}$

Step-by-step explanation:

The slope can be calculated with the following formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Then, knowing that the line passes through the points (2,1) and (-1,-1), we can substitute the coordinates into the formula.

In this case:

$y_2=-1\\y_1=1\\x_2=-1\\x_1=2$

Therefore, the slope of the line that passes through the points (2,1) and (-1,-1) is:

$m=\frac{-1-1}{-1-2}\\\\m=\frac{-2}{-3}\\\\m=\frac{2}{3}$

Find the value of the test statistic z using z=^p−p√pq/n.

Anna007 [38]

Answer:

Option C - 4.71

Step-by-step explanation:

We are given the Test statistic for proportion as;

z = (^p − p)/√pq/n

From the question;

^p = 0.15

p = 0.1

q = 1 - 0.1 = 0.9

n = 800

z = (0.15 - 0.1)/√(0.1 × 0.9/800)

z = 0.05/√(0.09/800)

z = 4.71

Correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.

klasskru [66]

F(x)=25-x^2
g(x)=x+5

f/g(x)=(25-x^2)/(x+5)

f(x) is in binomial form so 25-x^2 can also be written as (5-x)(5+x)

so

f/g(x)=(5-x)(5+x)/(x+5)
f/g(x)=5-x
