Y = 1/2x - 4 Slope: X-intercept: Y-intercept:

ValentinkaMS [17]

Answer:

Slope = $\frac{1}{2}$ , X-intercept = 8 , Y-intercept = -4

Step-by-step explanation:

the following equation is given in slope intercept form which is y = mx + b where m is the slope and b is the y intercept

since m = $\frac{1}{2}$ and b = -4, we can say our slope is $\frac{1}{2}$ and y intercept is -4.

Recall that x intercept occurs when y = 0 so plug y = 0 in the equation then solve for x

0 = $\frac{1}{2}$ x - 4

add 4 to both sides,

4 = $\frac{1}{2}$ x

multiply by 2 on both sides,

4*2 = x

8 = x

x = 8

so our x-intercept is 8

Convert 48°36'12" to the nearest thousandth of a degree

uranmaximum [27]

48 degrees remains

divide minutes by 60

36/60 = 0.6

then divide seconds by 3600

12/3600=0.003 ( to nearest thousandth)

now add them all up

48 +0.6 + 0.003 = 48.603 degrees

Doing research for insurance rates, it is found that those aged 30 to 49 drive an average of 38.7 miles per day with a standard

Alja [10]

Answer: 0.4302

Step-by-step explanation:

Given : Mean : $\mu=\text{38.7 miles }$

Standard deviation : $\sigma=\text{6.7 miles }$

Sample size : $n=60$

Also, these distances are normally distributed.

Then , the formula to calculate the z-score is given by :-

$z=\dfrac{x-\mu}{\sigma}$

For x=32.5

$\\\\ z=\dfrac{32.5-38.7}{6.7}=-0.925373134\approx-0.93$

For x=40.5

$\\\\ z=\dfrac{40.5-38.7}{6.7}=0.268656\approx0.27$

The p-value = $P(-0.93$

$=P(0.27)-P(-0.93)=0.6064198- 0.1761855=0.4302343\approx0.4302$

Hence, the required probability :-0.4302
