Use the graph to find the value of f(x) when x = 9 for the function f (x) =
1
3
x − 3.

Answers

Answer 1

Step-by-step explanation:

this looks totally like

f(x) = 1/3 x - 3

to me.

because

f(0) = -3

f(3) = -2

f(6) = -1

so, f(9) = 1/3 × 9 - 3 = 3 - 3 = 0

f(9) = 0

you did not list that as answer option, but that is the correct answer.

David’s mom recorded the amount of time David spent on homework.

Which measure of central tendency should David’s mom use if she wanted to argue that David did not spend enough time on homework?

Answers

The measure of central tendency that David's mum can use to argue is the mean.

What is the Mean of a Data?

The mean of a data is the average of the data points in the data distribution. The mean is a measure of central tendency.

If David really spent enough time on homework, the average of the time he uses will give David's mum the mean time spent by David, which she can use for her argument.

Thus, David's mum can use the mean as a measure of central tendency.

If using the method of completing the square to solve the quadratic equation x^2-11x-14=0, which number would have to be added to "complete the square"?

Answers

Answer:

±√177/2+11/2

Step-by-step explanation:

Use the formula (b/2)^2 in order to create a new term. Solve for x by using this term to complete the square. Exact Form:x=±√177/2+11/2

x=12.15206734…,−1.15206734…

Answer:

30.25

Explanation:

Quadratic Equation: x² - 11x - 14 = 0

Number added = (b/2)² = (-11/2)² = 30.25

Solving Steps:

x² - 11x = 14

[add both sides by 30.25]

x² - 11x + 30.25 = 14 + 30.25

[complete square]

(x - 5.5)² = 44.25

[exchange sides]

(x - 5.5)² - 44.25 = 0

The mean weight of 8 girls in a group is 35 kg. The individual weights of seven of then
are 35kg, 28kg, 43kg, 25kg, 33kg, 51kg, and 22kg. Find the weight of the 8th girl.

Answers

The weight of the 8th girl in the class is 43 kg

How to determine the weight of the 8th girl?

The given parameters are:

Mean weight = 35 kg

Weight of 7 girls = 35kg, 28kg, 43kg, 25kg, 33kg, 51kg, and 22kg

Let the weight of the 8th girl be x.

Mean is calculated using:

Mean = Sum/Count

So, we have:

(35+ 28+43+25+33+51+22 + x)/8 = 35

Evaluate the sum

(237 + x)/8 = 35

Multiply both sides by 8

237 + x = 280

Subtract 237 from both sides

x = 43

Hence, the weight of the 8th girl is 43 kg

What is the probability you spin something larger than 10

Answers

The probability you spin something larger than 10 will be 1 / 2.

What is probability?

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

The given data is:-

There are 8 numbers in the spinner.We need to find the probability of a number greater than 10.

The probability will be calculated as:-

Total numbers = 8

Numbers greater then 10 are = 13 , 16 , 22 , 42 = 4

Probability = 4 / 8 = 1 / 2

Therefore the probability you spin something larger than 10 will be 1 / 2.
