What weight would give a newborn a z-score of −0. 75? grams.

Mariana [72]

The weight would give a newborn a z-score of −0. 75 with mean 3500 g and standard deviation 500 g is 3125 grams.

<h3>What is the normally distributed data?</h3>

Normally distributed data is the distribution of probability which is symmetric about the mean.

The mean of the data is the average value of the given data. The standard deviation of the data is the half of the difference of the highest value and mean of the data set.

A newborn who weighs 2,500 g or less has a low birth weight. use the information on he right to find the z score of a 2,500 g baby.

From the given parameters, the mean of the data is,

$\mu=3500$

The standard deviation of the data is,

$\sigma=500$

Thus, the z score can be given as,

$z=\dfrac{x-\mu}{\sigma}\\-0.75=\dfrac{x-3500}{500}\\x=3125$

Hence, the weight would give a newborn a z-score of −0.75 with mean 3500 g and standard deviation 500 g is 3125 grams.

The perimeter of parallelogram ABCD is 96 cm. AD is 3 cm more than twice AB. Find the lengths of all four sides of ABCD.

Elan Coil [88]

Step-by-step explanation:

perimeter of parallelogram=2(AD+AB)

Also, AD=2AB+3

So,

96=2(2AB+3+AB)

48=3AB+3

45=3AB

therefore,AB=15cm=CD

Also,AD=BC=2AB+3

=2×15+3

=33

the perimeter of a rectangle if 24 inches. the rectangle is enlarged so that each side is twice as long as the original. what ef

patriot [66]

The perimeter becomes double when each side is twice as long as the original.

According to the statement

we have given that the perimeter of a rectangle is 24 inches. and we have to find that the what effect does this enlargement have on the perimeter.

So, For this purpose, we know that the

A rectangle is a parallelogram all of whose angles are right angles especially : one with adjacent sides of unequal length.

The formula to find the perimeter of rectangle is 2(L + B)

And we the length is goes to increased by double then the perimeter will also goes to double.

Because perimeter is directly proportional to the length and breadth of rectangle.

So, The perimeter becomes double when each side is twice as long as the original.

80g + 30h = 10(g + h)

vladimir2022 [97]

Assignment: $\bold{Simplify \ Expression: \ 80g+30h=10\left(g+h\right)}$

<><><><><><><>

Answer: $\boxed{\bold{g=-\frac{2h}{7}}}$

<><><><><><><>

Explanation: $\downarrow\downarrow\downarrow$

<><><><><><><>

[ Step One ] Expand $\bold{10\left(g+h\right): \ 10g+10h}$

$\bold{80g+30h=10g+10h}$

[ Step Two ] Subtract 30h From Both Sides

$\bold{80g+30h-30h=10g+10h-30h}$

[ Step Three ] Simplify

$\bold{80g=10g-20h}$

[ Step Four ] Subtract 10g From Both Sides

$\bold{80g-10g=10g-20h-10g}$

[ Step Five ] Simplify

$\bold{70g=-20h}$

[ Step Six ] Divide Both Sides By 70

$\bold{\frac{70g}{70}=\frac{-20h}{70}}$

[ Step Seven ] Simplify

$\bold{g=-\frac{2h}{7}}$
