Evaluate the expression when m=7 and n=5.

8n+m

what is the answer?

Answer:

A, B, and C

not D or E

Step-by-step explanation:

A: the mean is 1.6 for group A compared to 2.5 of group B

B: the median is 1.5 for group A compared to 2.5 of group B

C: the mode is 3 for A and the mode is 5 for B

therefor, abc :)

The three statements that are true about the measures of the centre are:

The median for Group A is 2.

The median for Group B is 3.

The mode for Group A is less than the mode for Group B.

We must tally up every dollar spent and divide it by the number of pupils in each group to determine the mean for each group.

The dot plots show that Group A is expected to have a mean that is lower than Group B because Group A has more values that are less than $2, which will lower the average.

Yet, based just on the dot plots, we cannot be certain of the precise values of the means. The claim "The mean for Group A is less than the mean for Group B" is therefore not always accurate.

When the data are organized in order, the median is the middle value. The dot plots show that Group A's median is 2 and Group B's median is 3, respectively. It follows that the claim "The median for Group A is less than the median for Group B" is untrue.

The value that appears the most frequently is the mode. The dot plots demonstrate that Group A has a mode of 1, while Group B has a mode of 3. The adage "The mode for Group A is less than the mode for Group B" is therefore accurate.

=======================================================

Explanation:

I recommend drawing it out to see what's going on. See the drawing below.

In the diagram, both angles are in the northeast corner of their four-corner configurations. They are both congruent corresponding angles. So that's why the second angle is also 95 degrees.

Side note: we could replace "northeast" with any of the other directions on the compass (such as southwest). All that matters is that they are in the same configuration.

Answer:

100,000

Step-by-step explanation:

Given :

Initial deposit = 40000

Amount of money = Initial deposit / Reserve rate

When reserve rate = 10% = 0.1

Amount of money = 40000 / 0.1 = 400,000

When reserve rate = 8% = 0.08

Amount of money = 40000 / 0.08 = 500,000

Difference = 500,000 - 400,000 = 100,000

Amount of money will increase by 100,000

Answer:

20 hours later.

Step-by-step explanation:

If all three buses leave at the same time, they will arrive back in the park in 20 hours. If we want them to arrive at the exact same time, we need to find the least common multiple of all the numbers because the time it takes to get back into the park are different and without using least common multiple they would all arrive at different times. So, the least common multiple is 20 becuase they all have 20 as a multiple. In 20 hours all of the buses will arive back in the park at the same time.

Answer:

0

Step-by-step explanation:

We can use the slope formula since we have two points

m = ( y2-y1)/(x2-x1)

   = ( -2- -2)/(3-14)

   = ( -2+2)/(3-14)

    = 0/-11

   = 0

Answer:

0 is the slope of the line that contains the points (14,-2) and (3,-2)

Step-by-step explanation:

To find , the slope is the slope of the line that contains the points (14 , -2)and (3, -2)

we using slope formula which is

Where,

m , is the slope

( y ² - y ¹ ) = ( 14 , - 2)

( x ² - x ¹) = (3, -2 )

Substitute the values into the formula

m = (( -2 )- ( -2 ) ) / (3 - 14 )

m= ( -2 + 2 ) / ( 11)

m = 0 / 11

m = 0

Therefore , 0 is the slope of the line that contains the points (14,-2) and (3,-2)

Answer:

a. 4 marks b. 9 questions

Step-by-step explanation:

a) Anu gets 8 correct answer and 12 incorrect answers what is her score?

Since Anu got 8 correct answer and 12 incorrect answers, and + 5 marks is given for every correct answer and (-3) marks are given for every incorrect answer, the total score for correct answers is number of correct answer × marks for correct answer = 8 × (+ 5) = 40.

Also,  the total score for incorrect answers is number of incorrect answer × marks for incorrect answer = 12 × (- 3) = -36.

Anu's total score = total score for correct answers + total score for incorrect answers = 40 + (-36) = 40 - 36 = 4 marks.

So, Anu scored 4 marks.

b) Sam answered all the questions and scored 28 marks though he got 11 correct answers.  How many incorrect answers had he attempted?

Let x be the number of incorrect answers. Since the marks for incorrect answers is -3, then his total score for incorrect answers is -3x.

Since Sam got 11 correct answers and is given + 5 marks for each correct answer, then his total score for correct answers is 11 × (+5) = +55.

Since he gets a total of 28 marks, we have that total score for incorrect answer + total score for correct answer = 28.

So, -3x + 55 = 28

Solving for x, we have

-3x = 28 - 55

-3x = -27

x = -27/-3

x = 9

Since x = 9, Sam attempted 9 incorrect questions.

.

Answer:

He or she attempted 9 incorrect answers

h = (p/0.7 - b) ÷ r

Step-by-step explanation:

Anastasia uses the equation p = 0.7(rh + b) to estimate the amount of take-home pay, p, for h hours worked at a rate of r dollars per hour and any bonus received, b. What is an equivalent equation solved for h?

Given:

p = 0.7(rh + b)

Divide both sides by 0.7

p / 0.7 = rh + b

p/0.7 - b = rh

p/0.7 - b ÷ r = h

h = (p/0.7 - b) ÷ r
