A Canadian study examined the pregnancy weight gain of underweight mothers, women who had been underweight before becoming pregnant. A Normal distribution with mean 36.6 lb and standard deviation 11.9 lb is a reasonable model for the distribution of pregnancy weight gains in this population.
a) Perform the appropriate computation and fill in the blank to complete this sentence in context: In this population, the first quartile of pregnancy weight gains is_____.
b) For underweight mothers, health organizations recommend a pregnancy weight gain between 27.5 lb and 39.5 lb. What is the probability that a randomly selected underweight mother in Canada would have a pregnancy weight gain in the recommended range?

Answers

Answer:

The correct answer is:

(a) 44.6 lb

(b) 0.371

Step-by-step explanation:

Given values are:

Mean,

[tex]\mu=36.6[/tex]

Standard deviation,

[tex]\sigma=11.9[/tex]

(a)

The z distance third quartile will be:

⇒ [tex]P(Z<0.674)=0.75[/tex]

                       [tex]z =0.674[/tex]

By using the z-score formula, we get

⇒ [tex]x=z\times \sigma+ \mu[/tex]

       [tex]=0.674\times 11.9+36.6[/tex]

       [tex]=44.62[/tex]

(b)

⇒ [tex]P(27.5<x<39.5) = P[{\frac{(27.5-36.6)}{11.9} <\frac{(x-\mu)}{\sigma} <\frac{(39.5-36.6)}{11.9} }][/tex]

                                  [tex]=P(-0.76<z<0.24)[/tex]

                                  [tex]=P(z<0.24)-P(z<-0.76)[/tex]

By using the z table, we get

                                  [tex]=0.5948-0.2236[/tex]

                                  [tex]=0.371[/tex]

Solve for x: 12x+5=3x+35

Answers

Answer:

The answer would be 3.33.

Step-by-step explanation:

Simplifying 12x + 5 = 3x + 35

Reorder the terms: 5 + 12x = 3x + 35

Reorder the terms: 5 + 12x = 35 + 3x

Solving 5 + 12x = 35 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation. 5 + 12x + -3x = 35 + 3x + -3x

Combine like terms: 12x + -3x = 9x 5 + 9x = 35 + 3x + -3x

Combine like terms: 3x + -3x = 0 5 + 9x = 35 + 0 5 + 9x = 35

Add '-5' to each side of the equation. 5 + -5 + 9x = 35 + -5

Combine like terms: 5 + -5 = 0 0 + 9x = 35 + -5 9x = 35 + -5

Combine like terms: 35 + -5 = 30 9x = 30

Divide each side by '9'. x = 3.333333333

Simplifying x = 3.333333333

now multiply each term by 7 to eliminate fraction:

14 + 7y = 3x

0° < x < 83.76°

Step-by-step explanation:

Assuming a pyramid with a square base, and the height of the pyramid varies from almost zero to almost infinity.

The largest value for the angle x+2 is when the height of the pyramid is almost zero.

Then the face is an isosceles triangle with base 13 and height 14.

The angle opposite the base is then

x+2  = 2*atan(6.5/7) = 2* 42.879 = 85.76°

when the height is almost infinite, the angle is almost zero.

Therefore the range of the value of x

0° < x < 83.76°

b) -2/11
a) 2/11
d) -11/2
c) 11/2

Answers

Answer:

c) 11/2

Step-by-step explanation:

(-4, 7) and (-6, -4)

To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(-4 - 7) / (-6 - (-4))

Simplify the parentheses.

= (-11) / (-6 + 4)

= (-11) / (-2)

Simplify the fraction.

-11/-2

= 11/2

This is your slope.

Answers

Answer:

-11 + 73

62°

Step-by-step explanation:

Morning temperature = - 11

Afternoon temperature = morning temperature + 73°

We obtain the temperature in the afternoon by adding the 73° increase in temperature temperature the morning temperature ;

Hence, temperature in the afternoon will be :

-11° + 73° = 62°

Necesito ayuda con este ejercicio hay que determinar el valor de la a: [tex]a^{20} : a^{2x} = a^{12}[/tex]

Answers

Answer:

x = 10 + log(1/a^12)/(2 log(a)) + (i π n)/log(a) for n element Z

Step-by-step explanation:

Solve for x:

a^(20 - 2 x) = a^12

Take reciprocals of both sides:

a^(2 x - 20) = 1/a^12

Take the logarithm base a of both sides:

2 x - 20 = log(1/a^12)/log(a) + (2 i π n)/log(a) for n element Z

Add 20 to both sides:

2 x = 20 + log(1/a^12)/log(a) + (2 i π n)/log(a) for n element Z

Divide both sides by 2:

Answer: x = 10 + log(1/a^12)/(2 log(a)) + (i π n)/log(a) for n element Z

At the store, Alyssa spent $3.25 on stickers and $6.50 on candy. She paid with a $10 bill. How much change did she get back?

Answers

A quarter or $0.25.

Answer:

$0.25

Step-by-step explanation:

First, find how much the stickers and candy cost in total:

3.25 + 6.50

= 9.75

Subtract this from 10 to find how much change she got back:

10 - 9.75

= 0.25

So, she got back $0.25 in change
