Answer:

62

Step-by-step explanation:

Turn the percentage into a decimal.

50% = 0.5

Divide.

31 / 0.5 = 62

Best of Luck!

Answer:

62

Step-by-step explanation:

50% is technically 1/2 right?

So, if 31 is half of this mysterious number then we just need to times 31 by 2.

Therefore, 31 * 2 = 62.

We can check this by multiplying 62 by .50 (remember that when using percents in an operation we move the decimal over twice)

62 * .50 = 31

I hope this helps!!

Answer:

11 and 12

Step-by-step explanation:

Let the consecutive integers be x and x+1

The lesser integer = x

The greater integer = x+1

Two times the greater of two consecutive integers is expressed as;

2(x+1) = 2x+2.

9 less than three times the lesser integer is expressed as;

3x - 9

Equate both expression

2x+2 = 3x - 9

2x-3x = -9-2

-x = -11.

x = 11

The greater integer = x+1 = 11+1 = 12

Hence the integers are 11 and 12

Answer:

The fraction of its drop height after the fourth bounce is

[tex]\displaystyle \frac{16}{625}[/tex]

Step-by-step explanation:

Let's suppose the rubber ball is dropped from a height H0. Every time the ball bounces back it reaches 8/10 of the initial drop height.

The ball's height H(x) after bounce number x is:

[tex]\displaystyle H(x)=H_o\left(\frac{8}{20}\right)^x[/tex]

Simplifying:

[tex]\displaystyle H(x)=H_o\left(\frac{2}{5}\right)^x[/tex]

After the fourth bounce, the height is:

[tex]\displaystyle H(4)=H_o\left(\frac{2}{5}\right)^4[/tex]

[tex]\displaystyle H(4)=H_o\frac{2^4}{5^4}[/tex]

[tex]\displaystyle H(4)=H_o\frac{16}{625}[/tex]

The fraction of its drop height after the fourth bounce is

[tex]\mathbf{\displaystyle \frac{16}{625}}[/tex]

Answer:

This population, the population is 45 fish.

Step-by-step explanation:

This problem can be solved by a rule of three.

Last year there were 60 fish in the lake. That was 100, that is, decimal 1.

This year it decreased 25%. So there 100%-25% = 75%, that is decimal 0.75. So

60 fish - 1

x fish - 0.75

x= 60*0.75

x=45

This population, the population is 45 fish. Please make the brainliest.

60-25% of 60 =number of fish this year

60-25/100 x 60

60-15

45 fish are present in the lake

Answer:

The mean and standard devaition of W are 6 and 31 respectively.

Step-by-step explanation:

Given that:

W = 7 + 2X

Variance (W) = Variance(7 + 2X)

For a term constant term, the variance is zero.

So;

[tex]W = Var (2X)[/tex]

W = 4 × Var(X)

W = 4 × (SD (X))²

W = 4 × (3)²

W = 4 × 9

W = 36

Thus, Variance (W) = 36

The standard deviation of W = [tex]\sqrt{variance}[/tex]

W = [tex]\sqrt{36}[/tex]

W = 6

Also;

E(W) = E(7 +2 X)

E(W) = 7 + 2 × E(X)

where;

mean X = 12

E(W) = 7 + 2(12)

E(W) = 31

Thus, the mean and standard devaition of W are 6 and 31 respectively.

The mean and the standard deviation of W are 31 and 6 respectively.

The given parameters are:

[tex]\mathbf{\bar x_x = 12}[/tex]

[tex]\mathbf{\sigma_x = 3}[/tex]

The definition of W is given as:

[tex]\mathbf{W = 7 + 2X}[/tex]

This means that:

[tex]\mathbf{Var(W) = Var(7) + Var(2X)}[/tex]

So, we have:

[tex]\mathbf{Var(W) = 0 + Var(2X)}[/tex] --- the variance of a constant term is 0

[tex]\mathbf{Var(W) = Var(2X)}[/tex]

This gives

[tex]\mathbf{Var(W) = 2^2 \times Var(X)}[/tex]

We have:

[tex]\mathbf{Var(X) = \sigma^2_x}[/tex]

So, the equation becomes

[tex]\mathbf{Var(W) = 2^2 \times \sigma^2_x}[/tex]

[tex]\mathbf{Var(W) = 2^2 \times 3^2}[/tex]

[tex]\mathbf{Var(W) = 36}[/tex]

The standard deviation is then calculated as:

[tex]\mathbf{\sigma_W = \sqrt{Var(W)}}[/tex]

[tex]\mathbf{\sigma_W = \sqrt{36}}[/tex]

[tex]\mathbf{\sigma_W = 6}[/tex]

The mean is then calculated as:

[tex]\mathbf{E(W) = E(7 + 2X)}[/tex]

This gives

[tex]\mathbf{E(W) = 7 + 2E(X)}[/tex]

So, we have:

[tex]\mathbf{E(W) = 7 + 2 \times 12}[/tex]

[tex]\mathbf{E(W) = 31}[/tex]

Hence, the mean and the standard deviation of W are 31 and 6 respectively.

Answer:

The arithmetic between 42 and 86 is 44

Step-by-step explanation:

Answer: y => 12

y is greater than or equal to 12

Step-by-step explanation:

So they give you the function of y = 2x + 4 and the domain of all real numbers is greater than or equal to 4.

In simple term, the domain is x => 4, x is greater than or equal to 4.

Using that we can substitute the x in the function by 4.

y = 2(4) + 4

y = 8 + 4

Which gave us the answer of 12.

Since the domain can be anything greater than 4 or 4. We can expect the

same for the range.

Then the range will be 12 or greater than 12. For example, 13, 14, 15, 16...

Ex. y = 2(5) + 4

y = 10 + 4

y = 14

Ex. y = 2(4.5) + 4

y = 9 + 4

y = 13

Answer:

put one number in front of the other

Answer:

24.04%

Step-by-step explanation:

Given that:

Mortgage = $238,000

Number of years = 30

Monthly payment without extra payment= $1220.09

Monthly payment with extra payment = $1420.09

Total amount paid :

Number of months * monthly payment

12 months = 1year

30 years = (30 * 12) = 360 months (without extra payment)

22 years 5 months = (22 * 12) + 5 = 269 months (with extra payment)

Amount paid without extra payment :

$1220.09 * 360 = $439232.4

Percentage of total loan paid as interest :

((439232.4 - 238000) / 238000) * 100%

= 0.8455142 = 84.55%

Amount paid with extra payment :

$1420.09 * 269 = 382004.21

Percentage of total loan paid as interest :

((382004.21 - 238000) / 238000) * 100%

= 0.6050597 = 60.51%

Difference between percentages:

84.55% - 60.51% = 24.04%

Answer:

9 cm

Step-by-step explanation:

The perimeter of a polygon is the sum of the lengths of all the sides of the polygon.

If a polygon is a triangle, and its 3 sides have length a, b, and c, then the perimeter is the sum of a, b,, and c.

perimeter = a + b + c

Here, the perimeter = 29 cm

The lengths of the sides are a = 8 cm, b = 12 cm, c = x.

8 + 12 + x = 29

x + 20 = 29

x = 9

Answer:

-∞ < y < ∞

Step-by-step explanation:

Range corresponds to the values on the y-axis and Domain corresponds to values on the x-axis. Here if see the graph the range depends on values on y-axis and we can see that the the graph goes to -∞(-negative infinity) to +∞(positive infinity)  so the answer is

-∞ < y < ∞

Answer:

The range is  -∞< y < ∞, below is the explanation of how to get range.

Step-by-step explanation:

Given:

      Graph of a function h(x).

To find:

      The range of the function in inequality notation.

The range is all possible y-values of the function. Let's find all possible y values from the graph.

If we see the graph, it has a vertical asymptote at x=1 and a slant asymptote.

But it tool all y values from -infinity to infinity.

So, we can write range as -∞< y < ∞ because both sides of the function go and so on below the x-axis and go and so on above the x-axis.

The range is  -∞< y < ∞ .

She added incorrectly

Step-by-step explanation:

Answer should be (22, -26) but Kelcy got wrong because she has taken -1 in third step instead of taking 1 because -4 +5 is 1.

A vector is a quantity or phenomenon that has two independent properties: magnitude and direction.

Let  u = ⟨9, –2⟩, v = ⟨–4, 3⟩, and w = ⟨5, 1⟩

3u – 5(v + w)

3(9, -2)-5(⟨–4, 3⟩+⟨5, 1⟩)

Multiply 3 to (9, -2) and add v and w

(27,-6)-5(1,4)

(27, -6)-(5, 20)

Subtract the vectors

(27-5, -6-20)

(22, -26)

The answer should be (22, -26) but Kelcy got wrong because she has taken -1 in third step instead f taking 1 because -4 +5 is 1.
