Answer: 0.7506

Step-by-step explanation:

Given :Mean : $\mu=\text{ 7.8 grams}$

Standard deviation : $\sigma =\text{ 0.2 grams}$

The formula for z -score :

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

For x= 7.65 ,

$z=\dfrac{7.65-7.8}{0.2}=-0.75$

For x= 8.2 ,

$z=\dfrac{8.2-7.8}{0.2}=2$

The p-value = $P(-0.75$

$=0.9772498-0.2266274=0.750622\approx0.7506$

Hence, the probability that the amount of protein is between 7.65 and 8.2 grams=0.7506.

XY = 4x, YZ = 3x, and XZ = 42

grin007 [14]

Answer:

x=6

XY=24 units

YZ=18 units

Step-by-step explanation:

we have that

Y is between X and Z

$XZ=XY+YZ$

substitute the given values and solve for x

$42=4x+3x\\42=7x\\x=6$

therefore

$XY=4x=4(6)=24\ units\\YZ=3x=3(6)=18\ units$
