Answer:

.

Step-by-step explanation:

The correct answer is 15.40

A decimal is a number that consists of a whole and a fractional part. Decimal numbers lie between integers.

Given that, a decimal number, 15.403

As we know, rounding a decimal number to two decimal places is the same as rounding it to the hundredths place, which is the second place to the right of the decimal point.

Therefore, Rounding to 2 decimal place, we get

Answer:

60 quarts of the 6% butterfat milk and 20 quarts of the 5% butterfat milk

Step-by-step explanation:

Set up an equation where x is the number of quarts of 6% butterfat milk:

(0.06)(x) + (0.02)(80 - x) = 80(0.05)

Simplify and solve for x:

0.06x - 0.02x + 1.6 = 4

0.04x + 1.6 = 4

0.04x = 2.4

x = 60

So, there needs to be 60 quarts of the 6% butterfat milk.

Since the total amount will be 80 quarts, this means there needs to be 20 quarts of the 5% butterfat milk.

So, the mixture should contain 60 quarts of the 6% butterfat milk and 20 quarts of the 5% butterfat milk.

Answer:

Step-by-step explanation:

[tex]7c - 5c + 4 = 4c - 10 [/tex]

Simplify the expression on the left side of the equation

That's

[tex]2c + 4 = 4c - 10[/tex]

Subtract 4 from both sides of the equation

[tex]2c + 4 - 4 = 4c - 10 - 4 \\ 2c = 4c - 14[/tex]

Subtract 4c from both sides of the equation

[tex]2c - 4c = 4c - 4c - 14 \\ - 2c = - 14[/tex]

Divide both sides by - 2

[tex] \frac{ - 2c}{ - 2} = \frac{ - 14}{ - 2} \\ [/tex]

We have the final answer as

Answer:

1) what percent of men are between 64.5 and 73.5 inches tall?

= 95.45%

2) what percent of men are taller than 71.25 inches?

= 15.866%

3) what is your z score? for ladies N(64,2)

= 2.5

4) what is the height that 90% of men in the us are taller than?

66.12 inches

Step-by-step explanation:

We solve using the z score formula

The formula for calculating a z-score is is z = (x-μ)/σ,

where x is the raw score

μ is the population mean

σ is the population standard deviation.

a) what percent of men are between 64.5 and 73.5 inches tall?

mean 69 inches and standard deviation 2.25.

For x = 64.5

z = (x-μ)/σ

= 64.5 - 69/2.25

= -2

Probability value from Z-Table:

P(x= 64.5) = 0.02275

For x = 73.5

z = (x-μ)/σ

= 73.5 - 69/2.25

= 2

Probability value from Z-Table:

P(x = 73.5) = 0.97725

Hence, percent of men are between 64.5 and 73.5 inches tall

= 64.5<x < 74.5

P(x = 73.5) - P(x = 64.5)

= 0.97725 - 0.02275

= 0.9545

Converting to percentage = 0.9545

× 100

= 95.45%

b) what percent of men are taller than 71.25 inches?

mean 69 inches and standard deviation 2.25.

For x = 64.5

z = (x-μ)/σ

= 71.25 - 69/2.25

= 1

Probability value from Z-Table:

P(x<71.25) = 0.84134

P(x>71.25) = 1 - P(x<71.25)

= 0.15866

Converting to percentage

= 0.15866 × 100

= 15.866%

The percent of men are taller than 71.25 inches is 15.866%

3) what is your z score? for ladies N(64,2)

z = (x-μ)/σ

Mean = 64, standard deviation = 2

x = 69

z = 69 - 64/2

z = 5/2

z = 2.5

4) what is the height that 90% of men in the us are taller than?

10th percentile confidence interval = 90% of men = -1.282

z = (x-μ)/σ

-1.282 = x - 69/2.25

-1.282 × 2.25 = x - 69

2.8845 = x - 69

x = 69 - 2.8845

x = 66.1155

Approximately = 66.12 inches

Exact Form: Root 5

Decimal Form: 2.23606797...

Step-by-step explanation:

Multiply the numerator and denominator by the conjugate.

The simplified evaluation of the given expression would be √5 in exact form or 2.23606797... in decimal form.

A rational number is defined as a numerical representation of a part of a whole that represents a fraction number.

It can be a/b of two integers, a numerator a, and a non-zero denominator b.

We have been the given expression as :

⇒ 5 √7/√35

∵ √35 = √7 ×√5

⇒ 5 √7/√(7×5)

Reduce the identical terms, and we get

⇒ 5 √7/(√7)×(√5)

⇒ 5 /√5

⇒ (√5 ×√5)/√5

∵ 5 = √5 ×√5

⇒ √5

Exact Form: √5

Decimal Form: 2.23606797...

Therefore, the simplified evaluation of the given expression would be √5 in exact form or 2.23606797... in decimal form.

Step-by-step explanation:

That look true but if it has number in between you will have to recheck the mid point

The statement is true.

The midpoint formula is applied when one is required to find the exact center point between two defined points.

Given statement:

M is the midpoint of AB.

As we can see from the figure we can say that the point M is seems to be equidistant from from point A and point B.

If there were measurement then this will be more clear,

But from figure it can be seen that M is midpoint of AB.

Answer:

SLOPE=7 Y-INTERCEPT=0

Step-by-step explanation:

First you find the rise over run. In this case it is 14/2 (it is hard to see, but that is what it looks like.)

Then divide 14/2 which equals 7.

Therefore the slope is 7.

The line intersects the y-intercept at the point 0.

So therefore the answer is 0.

The equation for this line would be y=7x+0 or just y=7x

This would mean that the graph is proportionate.

Convert fraction (ratio) 200 / 500 Answer: 40%

The solution is 150 %

The percentage change from 200 to 500 is 150 %

What is Percentage Error?

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage error is the difference between the measured value and the true value , as a percentage of the true value

Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100

Given data ,

Let the percentage change be represented as A

Now , the value of A is

Let the first number be P = 200

Let the second number be Q = 500

Percentage change = [ ( |first number- second number | ) / True Value]x 100

Substituting the values in the equation , we get

Percentage change A = ( | 200 - 500 | / 200 ) x 100

Percentage change A = ( 300 / 200 ) x 100

Percentage change A = 1.5 x 100

Percentage change A = 150 %

Therefore , the value of A is 150 %

Hence , the percentage change is 150 %

Answer:

[tex]b = 25.66m[/tex]

Step-by-step explanation:

The perimeter of this rectangle equals

[tex]2l + 2b = 154m[/tex]

First, convert the 2 centimeters to meters.

[tex]1m = 100cm \: \: \: or \: \: \: 0.01m = 1cm[/tex]

[tex]2cm = 0.02m[/tex]

Then write an equation for the length in terms of the breadth.

[tex]l = 2b + 0.02m[/tex]

Next, plug in the equation for L into the equation for the rectangle...

[tex]2(2b + 0.02m) + 2b = 154m[/tex]

now, solve for b...

multiply 2 through the parentheses...

[tex]4b + 0.04m + 2b = 154m[/tex]

subtract 0.04m from both sides and add the b terms together...

[tex]6b =153.96m[/tex]

then divide both sides by 6

[tex]b = 25.66m[/tex]
