A-65.2
B-192
C-39
D-13.2

Answers

Answer: it's c

Step-by-step explanation:The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

56+21+55+30+33/5=39

Answer: i think the answer is 39

Step-by-step explanation: the mean is the average of all the numbers so you would add 56+21+55+30+33 =195 you would then dived the total by the amount of numbers there are in this situation there are 5 so you would do 195diveded by 5 which = 39 I hope this makes since and this helps if this is not what your asking plz clarify :)

The table shows the relationship between the number of drops of food color added to different number of cups of cake frosting:


Cups of
Frosting Drops of
Food Color
2 6
3 9

Which point below shows an equivalent ratio in this situation?

A graph is shown. The title of the graph is Cake Decorating. The horizontal axis label is Frosting in cups. The horizontal axis values are 0, 10, 20, 30, 40, 50, 60. The vertical axis label is Food Color in drops. The vertical axis values are 0, 30, 60, 90, 120, 150, 180. Point C is plotted on the ordered pair 60,20, and Point M is plotted on the ordered pair 50, 150.

A. Point M, because if drops of food coloring are 50, then cups of frosting will be 150

B. Point M, because if cups of frosting are 50, then drops of food coloring will be 150

C. Point C, because if cups of frosting are 60, then drops of food coloring will be 20

D. Point C, because if drops of food coloring are 60, then cups of frosting will be 20

Students in the science lab are measuring the mass of an object on a triple beam balance. The object has a mass of 38 grams. Complete the table below with the absolute and percent error for each students’ measurement. Round your answer to the nearest tenths place.

Answers

Answer:

The answer is 40

Step-by-step explanation:

have a nice day!

The absolute error of Danielle, Iris, and HB is 2,6 and 1 gram respectively. The percentage error of Danielle, Iris, and HB  are 5%,15%, and 2.5%  respectively.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Actual mass = 38

Danielle error = 40 - 38 = 2 grams

% error = 2/40 x 100 = 5%

Iris error = 4 - 34 = 6 grams

% error = 6/40 x 100 = 15%

HB error = 41 - 40 = 1 grams

% error = 1/40 x 100 = 2.5%

Hence "The absolute error of Danielle, Iris, and HB is 2,6 and 1 gram respectively. The percentage error of Danielle, Iris, and HB  are 5%,15%, and 2.5%  respectively".

Gloria wants to make beef stroganoff for 12 people. Her recipe serves 8 people and calls for 4.5 pounds of ground beef. How much ground beef should Gloria purchase?

Answers

Answer:

6.75 pounds

Step-by-step explanation:

This question is of direct variation. We will use x as our answer. 8 is 2/3 of 12, so 4.5 should be 2/3 of x. We can now make an equation.

In order to solve the equation, we multiply both sides by the reciprocal of 2/3, which is 3/2.

* stands for multiplication

From solving our equation, we get 6.75. We can't forget the units, so the answer is 6.75 pounds.

Which of the following is E ∪ F?
D = {x|x is a whole number}
E = {x|x is a perfect square between 1 and 9}
F = {x|x is an even number greater than or equal to 2 and less than 9}

1. {4}
2. {3, 4, 5, 6, 7, 8}
3. {2, 3, 4, 5, 6, 7, 8}
4. {2, 4, 6, 8}

Answers

For E the answer is 2. Because the square of 1 is one and 9 is three. And 2 to the square root of two which would be 2 time 2= 4

Answers

Answer:

1. 2,3; -2, 3

2. Both points share common values, but their absolute values for the x-value vary.

3. 2,3; 2, -3

4. Both points share common values, but their absolute values for the y-value vary.  

Step-by-step explanation:

For 1, the answer is thus:

-On the graph, the original point is 2, 3.

-A reflection over the y-axis changes the x-value, so it would be -2,3.

Similar for the next chart:

-The initial point is 2,3.

-A reflection over the x-axis changes the y-value, so the reflected point would be 2, -3.

The explanation is:

Both points have similar values except with differences in the absolute value.

Hope this helps you.

I will write the steps to find the slope and y-intercept from a graph.

Answers

Y-INTERCEPT: It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.

SLOPE:The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

The Y intercept is where the line crosses the Y axis on a graph. On an equation in the form Y=Mx+B it would be the +B. On an equation the slope is always the Mx
