The department of public safety has an old memo stating that the number of accidents per week at a hazardous intersection varies
marysya [2.9K]

Answer:

C. 0.1515

Step-by-step explanation:

The main objective here is to find the P-value for the test of H_0

Given that ;

the mean value = 2.2

the standard deviation = 1.4

number of recorded accident per week = 52

The null  hypothesis is : H_o: \mu =2

The alternative hypothesis is : H_A = \mu < 2

The Z- value can be calculated as:

z = \dfrac{x- \mu}{\dfrac{\sigma }{\sqrt{n}}}

z = \dfrac{2- 2.2}{\dfrac{1.4 }{\sqrt{52}}}

z = \dfrac{- 0.2}{\dfrac{1.4 }{7.211}}

z = -1.03

From the normal distribution table for probability;

P(z< -1.03 ) = 0.1515

B.

Step-by-step explanation:

Since 21 is divided by 3 you might think that it is equivalent but remeber you have to divide by both sides, so if you divide 21 by 7 it works but 28 by seven does not! Hope this helps!

PLEASE HELP QUICK!!!!! Find the value of x
dangina [55]

Answer:

x = 22

Step-by-step explanation:

158 + x + 148 + 32 must sum up to 360 as this is a quadrilateral.  Thus:

x + 338 = 360.

Subtracting 338 from both sides, we get x = 22
