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:

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

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

Answer:

4a (n-1) + 5

Step-by-step explanation:

1th=6

2nd=29

nth

if n=2

a2 = 4a(2-1) + 5 = 4 a(1) + 5 = 4 (6) + 5= 29

a3 =4a(3-1) + 5 = 4 a(2) + 5 = 4 (29) + 5= 121

try finding a4, check wether the answer is 489

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:

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:

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

Answer:

D. Obtuse

Step-by-step explanation:

Answer:

Obtuse

Step-by-step explanation:

An obtuse angle is anything that is greater than 90 degrees but less than 180. If it was 180 the angle would be flat but if it was 90 it would be right. Because this is in the middle it is obtuse.

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
