The City of Irvine upgraded a bicycle lane in a section of road to have a physical barrier between the cyclists as opposed to ju
____ [38]

Answer:

The p-value of the test is 0 < 0.05, which means that there is significant evidence to conclude that more people utilize the bike lane after the change.

Step-by-step explanation:

Before the upgrade, on any given day, it was known that the section of road saw an average of 350 unique cyclists. Test if more people are using now.

At the null hypothesis, we test if the same number of people is still using, that is, the mean is 350. So

H_0: \mu = 350

At the alternate hypothesis, we test if this mean increased, that is:

H_1: \mu > 350

The test statistic is:

t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}

In which X is the sample mean, \mu is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.

350 is tested at the null hypothesis:

This means that \mu = 350

After the upgrade, they took a random sample of 35 days in the year and counted the number of unique cyclists each day. The average was 405 cyclists with a standard deviation of 25.

This means that n = 35, X = 405, s = 25.

Test statistic:

t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}

t = \frac{405 - 350}{\frac{25}{\sqrt{35}}}

t = 13.02

P-value of the test and decision:

The p-value of the test is the probability of finding a sample mean above 405, which is a right-tailed test with t = 13.02 and 35 - 1 = 34 degrees of freedom.

Using a t-distribution calculator, this probability is of 0.

The p-value of the test is 0 < 0.05, which means that there is significant evidence to conclude that more people utilize the bike lane after the change.

A circle is centered at the point (-7, -1) and passes through the point (8, 7).The radius of the circle is____ units. The point
denis-greek [22]

Answer:

Part 1) The radius of the circle is r=17 units

Part 2) The points (-15,14) and (-15,-16) lies on this circle

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The distance between the center of the circle and any point on the circle is equal to the radius of the circle

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

(-7, -1) and (8, 7)

substitute

r=\sqrt{(7+1)^{2}+(8+7)^{2}}

r=\sqrt{(8)^{2}+(15)^{2}}

r=\sqrt{289}

r=17\ units

step 2

Find out the y-coordinate of point (-15,y)

The equation of the circle in standard form is equal to

(x-h)^2+(y-k)^2=r^2

where

(h,k) is the center

r is the radius

substitute the values

(x+7)^2+(y+1)^2=17^2

(x+7)^2+(y+1)^2=289

Substitute the value of x=-15 in the equation

(-15+7)^2+(y+1)^2=289

64+(y+1)^2=289

(y+1)^2=289-64

(y+1)^2=225

square root both sides

(y+1)=(+/-)15

y=-1(+/-)15

y=-1(+)15=14

y=-1(-)15=-16

therefore

we have two solutions

point (-15,14) and point (-15,-16)
