Answer:

a:b = 100:1

Step-by-step explanation:

Given:

a is 100% more than b

Find:

a:b

Computation:

Assume;

Common multiply = p

So,

b = p

a = 100P

a:b = 100p : p

a:b = 100:1

Answer:

0.999 = 99.9% probability that the baby weighs less than 150 Oz.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

The weights of newborn babies are distributed normally, with a mean of approximately 105 Oz and a standard deviation of 15 Oz.

This means that [tex]\mu = 105, \sigma = 15[/tex]

What if the probabability that the baby weighs less than 150 Oz?

This is the pvalue of Z when X = 150. SO

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{150 - 105}{15}[/tex]

[tex]Z = 3[/tex]

[tex]Z = 3[/tex] has a pvalue of 0.999

0.999 = 99.9% probability that the baby weighs less than 150 Oz.

It is the answer..

Answer:

20

Step-by-step explanation:

Answer:

96%

Step-by-step explanation:

assume the whole number is x

the first thing is decreasing by 20 %

x - 20%x = 80% x

then now the 80%x is the whole number  

now It's the turn of increasing

80%x + 20% * (80% x) = 80%x + 16%x = 96% x

I hope this is hlepful to you !!!!

what is the rest of the question like in what form

Answer:

n=3

Step-by-step explanation:

distribute, then add 3 to both sides, then divide both sides by 3

Answer:

n = 3

Step-by-step explanation:

3(n−1)=6

Step 1: Simplify both sides of the equation.

3(n−1)=6

(3)(n)+(3)(−1)=6(Distribute)

3n+−3=6

3n−3=6

Step 2: Add 3 to both sides.

3n−3+3=6+3

3n=9

Step 3: Divide both sides by 3.

3n/3  = 9/3\

n= 3

Hey there!

To find the value of x in an equation, you have to solve for x.

Example

Given: 3x - 9 = 0

First, add 9 to both sides:

3x = 9

Then, divide both sides by 3

x = 3

(-4,-2) is a solution of a given system of equation

Step-by-step explanation:

Explanation:-

Given that the equation

                y = 2 x + 6 ..(i)

Given point (-4,-2)

substitute   x =-4 and y = -2 in equation (i)

             -2 =2(-4) +6

            -2  = -8+6

           -2 =-2

∴ The point satisfies the given equation

Answer:

y = 1/4x - 3/2

Step-by-step explanation:

for slope, use formula (y2-y1)/(x2-x1):

(-1-(-2))/(2-(-2))

=1/4

use formula y=mx+b for equation:

y=1/4x+b (substitute x and y for either (-2, -2) or (2, -1))

-1=1/4(2)+b

-1=1/2+b

-3/2 = b

equation:

y = 1/4x - 3/2

Answer:

[tex]\huge\boxed{x=10}[/tex]

Step-by-step explanation:

Look at the picture.

[tex]\dfrac{3x}{y}=\dfrac{4x+20}{2y}\qquad|\text{cross multiply}\\\\(3x)(2y)=(y)(4x+20)\qquad|\text{divide both sides by}\ y\\\\(3x)(2)=4x+20\\\\6x=4x+20\qquad|\text{subtract}\ 4x\ \text{from both sides}\\\\6x-4x=4x-4x+20\\\\2x=20\qquad|\text{divide both sides by 2}\\\\\dfrac{2x}{2}=\dfrac{20}{2}\\\\x=10[/tex]

Answer:

the slope is 2

Step-by-step explanation:

to find slope all you need to do is look at the places where the line and the graph intersect. you should be able to find atleast 2 places. Once you have done that, count up how ever many spaces it is until you are on the same line with the place where the line intersects with the graph remember that number in your head, then could left or right until you are on top of the other place where it intersects, remember that number. In this case I counted 2 spaces up and 1 space to the left which gave me 2/1 which is 2

hope this helps. have a good day!

[tex]77 {m}^{2} [/tex]

Step-by-step explanation:

Given,

Height of the parallelogram = 7m

Base of the parallelogram = 11 m

Therefore, area of the parallelogram = b × h

Answer:

GCF = x

Step-by-step explanation:

The factor decomposition is:

7 * x   for the first term

2 * 2 * x for the second term.

The ONLY common factor is "x", and the maximum power at which it appears in BOTH terms is "1" (one)

Therefore GCF = x
