Answer:

n = 96

Step-by-step explanation:

[tex]66\frac{2}{3}[/tex] % = [tex]\frac{200}{3}[/tex] %

[tex]\frac{64}{n}[/tex] = [tex]\frac{\frac{200}{3} }{100}[/tex]

[tex]\frac{\frac{200}{3} }{100}[/tex] = [tex]\frac{2}{3}[/tex]

[tex]\frac{64}{n}[/tex] = [tex]\frac{2}{3}[/tex]

2n = 192 ⇒ n = 96

Answer:

The probability is;

0.076

Step-by-step explanation:

The count of numbers from 1 to 100 is 100

Let’s find the number of odd numbers

We can use;

a + (n-1)d = T

a is 1, d is 2 and T is 99

Thus;

1 + 2(n-1) = 99

n-1 = (99-1)/2

n-1 = 59

n = 50

So there are 50 odd numbers

Probability of selecting an odd number is 50/100 = 1/2

If all 4 are odd, we have 1/2^4 = 1/16

Let’s get the multiples of 3

we can use

a + (n-1)d = T

a = 3, n = ? , d = 3 and T = 99

So;

3 + 3(n-1) = 99

n-1 = 34

n = 33

So the probability is 33/100

All 4 are divisible will give 33/100^4

Multiples of 5

a + (n-1)d = T

a = 5, n = ? , d = 5 T = 100

5 + (n-1)5 = 100

5(n-1) = 95

n-1 = 19

n = 20

Probability is 20/100 = 1/5

All

four are multiples of 5

1/5^4 = 1/625

So the probability is;

1/16 + 1/625 + 0.01185921

= 0.0625 + 0.0016 + 0.01185921 = 0.07595921

Answer:

Assuming you want me to simplify your answer, the answer to your question is x/8-15.

Step-by-step explanation:

Simplify each term by combining 1/4 and x, and then combine x and 1/8 to get -9+x/4-6-x/8. Subtract 6 from -9 for x/4-15-x/8. Write x/4 as a fraction with a CD (Common Denominator) by multiplying by 2/2. Write each expression with a CD of 8. Combine the numerators, subract x from x*2 by reordering x and 2 to get 2*x-x/8-15. Then subract x from x to get x/8-15.

Answer:

10

Step-by-step explanation:

Strategy Keep change flip

Only use this strategy when dividing fraction not adding subtracting or multiplication

5/6 ÷1/12 would change to 5/ times 12/1

5/6 times 12/1 =60/6.

That an improper fraction so you see how many times 6 goes into 60 which is 10 times so the answer is 10

Step-by-step explanation:

it should be reflection over the y-axis then reflection over the x-axis

Answer:

A. 7,348

Step-by-step explanation:

P = le^kt

intitial population = 500

time = 4 hrs

end population = 3,000

So we have all these variables and we need to solve for what the end population will be if we change the time to 6 hours. First, we need to find the rate of the growth(k) so we can plug it back in. The given formula shows a exponencial growth formula. (A = Pe^rt) A is end amount, P is start amount, e is a constant that you can probably find on your graphing calculator, r is the rate, and t is time.

A = Pe^rt

3,000 = 500e^r4

now we can solve for r

divide both sides by 500

6 = e^r4

now because the variable is in the exponent, we have to use a log

[tex]log_{e}(6) = 4r[/tex]

ln(6) = 4r

we can plug the log into a calculator to get

1.79 = 4r

divide both sides by 4

r = .448

now lets plug it back in

A = 500e^(.448)(6 hrs)

A = 7351.12

This is closest to answer A. 7,348

Graph 2 has opposite expressions

Start by calculating the equations of the functions.

From the graphs, we have the following equations

An opposite function is defined by y = f(x) and y = f(-x)

Graph 1 is an absolute value graph.

Check if y = f(x) and y = f(-x) is true for function 2.

We have:

[tex]f(x) = 2x - 2[/tex]

[tex]f(-x) = 2(-x) - 2[/tex]

[tex]f(-x) = -2(x) - 2[/tex]

For graph 2, f(x) and f(-x) are true.

Hence, graph 2 has opposite expressions

3(22)−(2)(2)(−3)−4(−3)2

Answer:

x = -11

Step-by-step explanation:

Equations

The image shows a right triangle with angles 70°, 90°, and x+31.

The sum of the internal angles of a triangle is 180°, thus:

70 + 90 + x + 31 = 180

Simplifying:

191 + x = 180

Subtracting 191:

x = 180 - 191

x = -11
