Matilda recently took a statistics quiz in her math class. in one question, 45 of 900 visitors at a local craft show were surveyed about the cost of admission to the show. Matilda incorrectly stated that the sample in this situation was represented by 900 visitors at the craft show.
a. what is Matilda's error?

b. what is the actual sample?

Answers

Answer 1

Answer:

A. Her error was that she thought that they were surveying the whole town so 900 would be the sample.

B. The actual sample is 45.  

Step-by-step explanation:

The actual sample is 45 because 45 people out of the 900 visitors (population) were surveyed.

Quadrilateral DEFG has vertices at D(3,4) E(8,6) F(9,9) G(4,7). Prove that DGEF is a parallelogram

Answers

Sorry I’m kinda lazy to graph it but here are the ways you can prove a parallelogram:
Both pairs of opposite sides are parallel.
Both pairs of opposite sides are congruent.
Both pairs of opposite angles are congruent.
Diagonals bisect each other.
One angle is supplementary to both consecutive angles (same-side interior)

Sarah had 8 guests at her birthday party. She cut her round cake into 12 equal slices. 8 of the slices were eaten. What is the angle measure of the cake that was left?​

Answers

Answer:120°

Step-by-step explanation:

Given

cake is cut into 12 equal pieces

We know the top view of cake is similar to circle .

So, if a circle is divided into 12 equal parts then

each part subtend an angle of

∅ = 360/12 = 30%

If 8 slices were eaten , then 4 slices are remaining

These 4 slices measure subtend equal angle at the center therefore

4 slice measure a total of 4 × ∅

➡️ 4 x 30°

➡️ 120°

As a fraction with a denominator of 7, the value 2/5 would have a numerator of ...

  (2/5)(7) = 2.8

Yolanda made $192 for 12 hours of work. At the same rate, how many hours would she have to work to make $272?​

Answers

Answer:

17 hours

take $192 and divide it by 12 so you know how much they make per hour

$192 / 12 = 16

then you're going to take $272 and divide it by what you know now - how much they make per hour (this will get you how many hours they worked)

$272 / 16 = 17

Three of the thirty computers are out of service. What percent of the computers are working​

Answers

Answer: 90%

Step-by-step explanation:

3/30= not working

This means that 27/30 computers are working.

To find the percentage divide each number by a number that both numbers are divisible by.

In this case both numbers can be divided by 3, and your number will now be 9/10. You can then multiply this number by 10, so your number is now 90/100 which equals 90%

The graph of function gis the graph of function f (x) = 2x2 + 5 after a
vertical stretch by a factor of 3. What is the function rule for function g?

Answers

Answer: g(x) = 6*x^2 + 15

Step-by-step explanation:

Suppose that we have a function y = f(x)

A vertical stretch by a factor of K is written as:

g(x) = K*f(x).

In this case, we have f(x) = 2*x^2 + 5.

And we know that g(x) is a f(x) after a stretch by a factor of 3.

Then we get:

g(x) = 3*f(x) = 3*(2*x^2 + 5) =  3*2*x^2 + 3*5 = 6*x^2 + 15

g(x) = 6*x^2 + 15

Factor 3x^2 - 2x - 1 ​

Answers

Answer:

(3x+1) (x-1)

Step-by-step explanation:

.................

The factored form of 3x² - 2x - 1 is (3x + 1)(x - 1).

To factor the quadratic expression 3x² - 2x - 1, we can look for two binomials that multiply together to give the original expression.

We need to find two binomials in the form (ax + b)(cx + d) that, when multiplied, result in 3x² - 2x - 1.

To factor this expression, we need to find two numbers that multiply to give 3 (the coefficient of x² term) and add up to -2 (the coefficient of the x term).

By trial and error or using factoring techniques, we find that the factors are (3x + 1) and (x - 1).

Therefore, the factored form of 3x² - 2x - 1 is:

(3x + 1)(x - 1).

A serving of cereal is 2/3 cup. There are 12 cups in the box. How many
servings of cereal are in the box?​

Answers

Answer:

A serving of a certain kind of cereal is 2/3 cup. There are 12 cups of cereal in the box. How many servings of cereal are in the box? There are 12/(2/3) = 12*(3/2) = 36/2 = 18 total servings.

Step-by-step explanation:

There are 18 servings of cereal in the box.

To find the number of servings of cereal in the box, we can divide the total number of cups in the box by the amount of cereal in each serving.

Given:

Serving size: 2/3 cup

Total cups in the box: 12 cups

To find the number of servings, we divide the total cups by the serving size:

12 cups ÷ (2/3 cup)

= 12 cups × (3/2)

= 36/2

= 18 servings

Therefore, there are 18 servings of cereal in the box.

There are two missing numbers. Twice the first plus the second is equal to 15. Also, three
times the first minus the second equals 20. What are the two numbers?

Answers

Answer:

Write a system of equations

Step-by-step explanation:

2x + y = 15

3x - y = 20

5x = 35

x = 7

2(7) + y =15

y = 1

The two missing numbers are x = 7 and y = 1.Let's denote the first missing number as "x" and the second missing number as "y".

From the given information, we can form the following equations:

Equation 1: 2x + y = 15

Equation 2: 3x - y = 20

We can solve this system of equations by elimination or substitution method.

Let's use the elimination method:

Multiply Equation 1 by 3 and Equation 2 by 2 to eliminate the "y" term:

Equation 1: 6x + 3y = 45

Equation 2: 6x - 2y = 40

Subtract Equation 2 from Equation 1:

(6x + 3y) - (6x - 2y) = 45 - 40

Combine like terms:

6x + 3y - 6x + 2y = 5

Simplify:

5y = 5

Divide both sides by 5:

y = 1

Substitute the value of "y" into Equation 1:

2x + 1 = 15

Subtract 1 from both sides:

2x = 14

Divide both sides by 2:

x = 7

Therefore, the two missing numbers are x = 7 and y = 1.
