Answer:

1) f⁻1(x)= x+2/123

2) f(0.02235)=0.75

3) x= 0.02235

Step-by-step explanation:

part 1)

given that

f(x)=123x-2

to find F⁻1(x) we put X = f⁻1(x) in the given function to obtain

f(f⁻1(x))=123xf⁻1(x)

-> x+123x f⁻1(x)-2(f(f^-1(f⁻1(x)-x+2/123

part 2 and 3

for f(x)=0.75 we put f(x)=0.75and then solve for "x"

0.75=123 times x-2

x+0.75+2/123=0.02235

Answer: D. 0.860

Step-by-step explanation:

In the table we can see that he rolled the cube 1000 times, and he recorded that 140 of those times he rolled a 5.

Then, the probability of rolling a 5 will be equal to:

P1 = 140/1000 = 0.14

Now, the probabilty of NOT rolling a 5, is equal to the rest of the probabilities, this is:

P2 = 1 - 0.14 = 0.86

then the correct option is D

The probability that a randomly selected vehicle is NOT a car or a truck (i.e., it's an SUV) given that it's silver or black is approximately -18.6167.

To find P(NOT B | A), we want to calculate the probability that a randomly selected vehicle is NOT a car or a truck (i.e., it's an SUV) given that it's silver or black.

First, let's find the probabilities of events A and B:

Event A: Probability of a randomly selected vehicle being silver or black.

Event B: Probability of a randomly selected vehicle being a car or a truck.

From the table, we can find the probabilities of A and B:

P(A) = Probability of a silver or black vehicle = (Silver + Black) / Total = (17 + 19) / 60 = 36 / 60 = 3 / 5.

P(B) = Probability of a car or a truck = (Car + Truck) / Total = (819 + 358) / 60 = 1177 / 60.

Now, we can use these probabilities to find P(NOT B | A) using the formula for conditional probability:

P(NOT B | A) = P(A AND NOT B) / P(A)

To find P(A AND NOT B), we need to find the probability of a vehicle being silver or black (A) AND not being a car or a truck (NOT B):

P(A AND NOT B) = P(A) - P(A AND B)

Now, we already have P(A) and P(B), so we can calculate P(A AND B):

P(A AND B) = P(A) * P(B) = (3/5) * (1177/60)

Now, subtract P(A AND B) from P(A) to get P(A AND NOT B):

P(A AND NOT B) = P(A) - P(A AND B)

Finally, we can calculate P(NOT B | A):

P(NOT B | A) = P(A AND NOT B) / P(A)

Plug in the values:

P(NOT B | A) = (P(A) - P(A AND B)) / P(A)

Calculate the values:

P(NOT B | A) = ((3/5) - ((3/5) * (1177/60))) / (3/5)

Simplify the expression:

P(NOT B | A) = (3/5) * (1 - (1177/60)) / (3/5)

Now, perform the calculations:

P(NOT B | A) = (3/5) * (1 - (1177/60)) / (3/5)

P(NOT B | A) = (3/5) * (1 - 19.6167) / (3/5)

P(NOT B | A) ≈ (3/5) * (-18.6167) / (3/5)

P(NOT B | A) ≈ -18.6167

In this question figure of pyramid is attached below the question .

Surface area of the rectangular pyramid :

Area of the Base = Length × Width

                            = 10 × 2 = 20 cm²

Area of Lateral #1 = [tex]\frac{1}{2}(P)(L)[/tex]

                             = [tex]\frac{1}{2}(10\times6.3)[/tex]

                             = 31.5 cm²

Area of Lateral #2 = [tex]\frac{1}{2}(8\times 2)[/tex]

                               = [tex]\frac{16}{2}[/tex]

                               = 8 cm²

Surface area of the pyramid = 20 + 2(31.5) + 2(8)

Step-by-step explanation:

6x9=54=(6*5)+(6*4)

6x9=54

54 is the number you are trying to get

6*5= 30

so now you need something to add up to 54

6*4=24

24+30=54

I'm assuming the function given is y = 9300(0.991)^x

If so, then the base of the exponent 0.991 is in the form 1+r

1+r = 0.991

r = 0.991-1

r = -0.009

The negative r value indicates a percent decrease.

Specifically it is a 0.9% decrease since 0.009 = 0.9/100 = 0.9%

Any time you have a percent decrease like this, the exponential function is undergoing decay.

Answer:

A

Step-by-step explanation:

Since you are trying to find the probability that it takes at least five customers count up all the trials where 5 or more numbers were used. Put that number over the total number of trials (15). The correct answer is  4/15

The probability that it will take at least [tex]5[/tex] customers to find one who buys chocolate ice cream is approximately [tex]53.33\%[/tex]

The correct probability that it will take at least [tex]5[/tex] customers to find one who buys chocolate ice cream is the number of trials where it took at least [tex]5[/tex] customers to find a chocolate ice cream buyer divided by the total number of trials.

Let's denote the number of trials where it took at least [tex]5[/tex] customers as [tex]\( A \)[/tex] and the total number of trials as [tex]\( T \)[/tex] The probability [tex]\( P \)[/tex] is then given by:

[tex]\[ P = \frac{A}{T} \][/tex]

From the given data, we have:

[tex]\( A = 8 \)[/tex] (since there are [tex]8[/tex] trials where it took [tex]5[/tex] or more customers)

[tex]\( T = 15 \)[/tex] (since there are [tex]15[/tex] trials in total)

Now, we can calculate the probability:

[tex]\[ P = \frac{8}{15} \][/tex]

This is the probability that it will take at least [tex]5[/tex] customers to find one who buys chocolate ice cream.

To express this probability as a percentage, we multiply by [tex]100[/tex]

[tex]\[ P(\%) = \frac{8}{15} \times 100 = \frac{800}{15} = 53.33\% \][/tex]

one pair of glasses = 2

42 - 20 - 2 = 20

gloves = 20

shoe + (weird person + glasses + pair of shoes) x glasses = ?

10 + (5 + 2 + 20 + 20) x 2 = 20

10 + 47 x 2 = 104

10 + 94 = 104

If you have 14 people that will each eat 2 muffins, a total of 28 muffins are needed. Since the batches make 12, 2 batches wouldn't be enough. It's always better to round up for these questions. Hope this helps! :)

The equivalent of the expression | - 12 + 3 | is 9 because after simplifying the expression inside the absolute value parentheses, -12 + 3 is -9 and the absolute value of -9 is 9.

The student is asking for the equivalent of the absolute value expression | − 12 + 3 |. To solve this, we have to simplify the expression inside the absolute value parentheses first, which means performing the operation −12 + 3. This results in −9, because when you add a positive number to a negative one, you effectively subtract the smaller number from the larger one, but keep the sign of the larger number.

The absolute value of a number is the distance of that number from zero on a number line, regardless of the direction, so the absolute value of −9 is 9. Therefore, the expression | − 12 + 3 | is equivalent to 9.
