Which value of x is a solution of the inequality?
​3x−3≥9

Step-by-step explanation:

the probabilty for exactly 48 people surviving is

(64 over 48) × 0.8⁴⁸ × 0.2¹⁶

the possible combinations of 48 people out of 64 associated with the probability of 48 survivors and 16 deaths.

"at least" is then sum of the probabilities of exactly 48, 49, 50, 51, ... 64 people surviving.

that is a longer calculation of these 17 possibilities.

they go

(64 over 48) × 0.8⁴⁸ × 0.2¹⁶ = 0.0714...

(64 over 49) × 0.8⁴⁹ × 0.2¹⁵ = 0.0933...

(64 over 50) × 0.8⁵⁰ × 0.2¹⁴ = 0.1119...

...

(64 over 63) × 0.8⁶³ × 0.2¹ = 0.00001004...

(64 over 64) × 0.8⁶⁴ × 0.2⁰ = 0.0000006277...

the sum is the probabilty (that at least 48 out of the 64 are alive at 64) of 0.8746...

the maximum single probability (for an exact number of survivors) is as expected at exactly 51 and exactly 52 survivors with a probability of 0.1229... for each case.

of course, this is around the expectation value of

64×0.8 = 51.2 (out of the 64 it is expected that per average 51.2 people survive and reach age 64).

Answer: 13 3/4

Step-by-step explanation:

The gopher’s new elevation relative to the surface of the ground will be

[tex]13 \frac{1}{4}[/tex] inches.

What is Addition?

A process of combining two or more numbers is called addition.

Given that;

A gopher is in a hole that is [tex]6 \frac{1}{4}[/tex] in. below the surface of the ground.

And, Then digs [tex]7 \frac{1}{2}[/tex]  in. deeper.

Now,

The gopher’s new elevation relative to the surface of the ground will be calculated as;

⇒ [tex]6 \frac{1}{4} + 7 \frac{1}{2}[/tex]

⇒ 25/4 + 15/2

Make denominators same as;

⇒ 25/4 + 30/4

⇒ (25 + 30) / 4

⇒ 55 / 4

⇒ [tex]13 \frac{1}{4}[/tex] inches.

Thus, The gopher’s new elevation relative to the surface of the ground will be [tex]13 \frac{1}{4}[/tex] inches.

Answer:

Hope this helps

Step-by-step explanation:

Since 16 ounces equal 1 pound, we’ll add 16 + 16, which is 32 ounces. For one half of a pound, simply divide the amount of ounces in a pound (16) by half. 16 divided by 2 is 8, so in total your answer would be 40 ounces in 2 1/2 pounds.

Answer:

$4????

Step-by-step explanation:

I searched 40% of 80 and got 32, then 1/4 of 32, which was 8, then that in half was 4. I am not sure if it is right or if 8 was the final answer.

Answer: [tex]\frac{7}{10}[/tex]

Step-by-step explanation:

2[tex]\frac{1}{10}[/tex] barrels of almonds to make 3 batches of granola bar.

We need to turn fraction 2[tex]\frac{1}{10}[/tex] into a mixed number

2[tex]\frac{1}{10}[/tex] → [tex]\frac{21}{10}[/tex]

Now we set up an equation.

[tex]\frac{\frac{21}{10} }{3} =\frac{x}{1}[/tex]

Solve for x by cross multiplying and dividing.

[tex]\frac{21}{10}[/tex] ÷ 3 (KCF)

[tex]\frac{21}{10}[/tex] × [tex]\frac{1}{3}[/tex] = [tex]\frac{21}{30}[/tex]

Now we simplify the fraction.

[tex]\frac{21}{30}[/tex] → [tex]\frac{7}{10}[/tex]

[tex]\frac{7}{10}[/tex] barrels of almonds were used in each batch.

75 is what percent of 150

Percentage Calculator:75 is what percent of 150=50

50

Answer:

75 is 50 percent of 150.

Step-by-step explanation:

This is a pretty simple concept. First of all for this question, you should have noticed that 75 is half of 150. 50% is equal to 1/2.

There are a couple of methods you could use to solve this problem, if you are using a calculator, a simple way to solve percentage problems is to do 75 divided by 150 (in this case) which gives you 0.50.

If you do not have a calculator and you have to do this on paper, you need to do the classic proportion method. Make two fractions, 75 over 150, and x over 100. (x is what is used to represent an unkown amount.)

We are using over 100 because that is what a percent represents: an amount that is a fraction of 100. now you need to cross multiply. That would be 75 x 100. That equals 7,500. Now cross multiply the other way. That is 150x or represent 150 times x. Now solve the equation 150x = 7,500. To solve this you need to isolate the variable, x by dividing the 150 multiplying the x. That is the coefficient. the attached number next to it. After you do that, you need to divided the other side of the equation by 150. 7,500 divided by 150 equals 50.

After that you will find that the equation shows the value x = 50. You have now found the value of x.

Answer:

Copies cost for the first case = $ 12

Copies cost for the second case =$16

Number of Copies = 4

Step-by-step explanation:

Let the number of copies = N

. for the first case: total cost (T1) = 38 + 3N

. for the second case: total cost (T2) = 34 + 4N

Determine the ‘N’ when the cost is equivalent

So, 38 + 3N = 34 + 4N

38 – 34 = 4N – 3N

N = 4

Therefore, number of copies = 4

Copies cost for the first case = 3 × 4 = $12

Copies cost for the second case = 4 × 4 = $16

#1.

Expression

[tex]\sf\longmapsto 38+3x[/tex]

#2

Expression

[tex]\sf\longmapsto 34+4x[/tex]

Now

[tex]\sf\longmapsto 4x+34=3x+38[/tex]

Step-by-step explanation:

Marcus uses a rule of (x+8, y-3). What will be the output if the input is (-2,1) and (0,-5).

If it is going off of the math functions then the outputs would be simple math -

(6, -2) -2+8 and -3+1; (8, -8) 0+8 and -5-3 [if im doing the correct functions].

The X and Y is what gets me when trying to answer if it is a function or not, I would say it is because the x and y values are given and they are their values are substituted, the actual function is adding the 8 to the X and subtracting the 3 from the Y.

Answer:

Part A: f(x) = 1.50x/g(x) = 0.01(3)^x-1

Part B: Option A:  $9 

Part C: Option B:  $1,771.47

Part D: The eighth bushel picked is when the exponential function exceeds the linear function.

Step-by-step explanation:

Part A: Write a function to model each option.

Option A:  f(x) = 1.50x, where x is the number of bushels of apples picked

Option B: g(x) = 0.01(3)^x-1, where x is the number of bushels of apples picked.

--------------------------------------------------------------------------------------------------------------

Part B: If Rachel picks six bushels of apples, which option should she choose?  

Option A:  $9    Option B:  $2.43   

Option A is better since what the number is would be higher.

1.50x6 = 9. If I were to do the same for option b, option a would end up higher.

--------------------------------------------------------------------------------------------------------------

Part C: If Rachel picks twelve bushels of apples, which option should she choose?  

Option A:  $18 Option B:  $1,771.47

After calculating both of them by multiplying by 12 for each, option B ends up to be much better.

--------------------------------------------------------------------------------------------------------------

Part D: How many bushels of apples does Lucy pick to make option B better for her than option A?

The eighth bushel picked is when the exponential function exceeds the linear function.

The relationship between the number of balls Lucia lost at the golf

courses can be expressed as an equation.

Reasons:

The given parameters are;

The number of balls Lucia loses at the Rolling Hills, r = 12 balls

The number of balls Lucia loses at the Meandering Meadows, m = 8 balls

The total number of balls Lucia lost after playin at Rolling Hills and Meandering Meadows = 100 balls

The relationship between r and m is therefore;

Number of balls lost at Rolling Hills + Number of balls lost at Meandering Meadows = 100

12 × r + 8 × m = 100

12·r + 8·m = 100

The equation that best represents the relationship between r and m is therefore; 12·r + 8·m = 100
