94,86,95,99,88,90

A. mean is 92

B. mean absolute deviation is 4

C. values differ from the mean by an average of 4

A.

94+86+95+99+88+90=552

552 divided by 6 = 92

mean = 92

C.

94-92=2

92-86=6

95-92=3

99-92=7

92-88=4

92-90=2

2+6+3+7+4+2=24

24 divided by 6 = 4

Answer:

The ratio of copper, nickel and zinc required in the alloy = 12 : 5 : 3

12 → copper

5x → nickel

3 → zinc

The weight of the alloy = 5 kg

*12x + 5x + 3x = 512x+5x+3x=5*

Copper is 12*1/4 which equals 3kg

Nickel is 5*1/4 which equals 1.25kg

Zinc is 3*1/4 which equals .75kg

Have a great day! Hope this helps!

Answer:

10/32 or 0.3125

Step-by-step explanation:

1) 3(3) + 1 / 4x4x2

2) 9+1 / 32

3) 10/32

4) Decimal form is 0.3125

Answer:

option B

Step-by-step explanation:

we first subtract 4 by both sides to get:

3x < -15

now we just divide by 3 on both sides to get

x < -5

the answer is B

Answer:

see below

Step-by-step explanation:

3x+4 less than or equal to -11

Subtract 4 to get 3x isolated

3x < -15

Because x still has something attached to it, you divide by 3

x is less than or equal to -5

Answer:

(4, 8) also known as option B. is the correct answer.

remember

x comes first

y comes second

and

x goes across

y goes up and down

Answer: the answer is ( 4, 8) which is the second choice .

Step-by-step explanation: the 4 is on the x axis line and the 8 is on the y axis line . So coordinates 4,8 represent E on the coordinateplane . HOPE IT HELPS YOU .PLEASE GIVE BRAINLIEST .THANKS .

Answer: 25%

Explanation: A fourth equals 1/4. If you divide 1 by 4, you get 0.25. Move the decimal points 2 points to the right, and you get 25% :Wicked:

Answer: 25% of the dozen are cracked

Step-by-step explanation: 1/4 is also 25%

Divide 1 by 4 which gives you 0.25, or 25%

Answer:

mark brainliest please!!! <33

Step-by-step explanation:

Since the slope is a positive slope, hence the term that best describes the graph of y = x – 1 is increasing

The standard equation of a line in slope-intercept form is expressed as:

y = mx + b

where:

The nature of the graph is determined by the slope value.

If the slope is positive, the graph is increasing while if the slope is negative, the graph is decreasing.

Given the function y = x - 1, compared with the general equation;

mx = 1x

m = 1

Since the slope is a positive slope, hence the term that best describes the graph of y = x – 1 is increasing

Answer:

The total change in the water level is [tex]-\frac{33}{28}[/tex]

Step-by-step explanation:

In order to get the total change in something is to add all the numbers together. So, over that three month period, you add -1 3/4-1/28-15/28. SInce you are adding fractions, it helps to have all the denominators the same. Change -1 3/4 into -49/28. (all I did was turn the fraction into an improper fraction then did  [tex]\frac{7*7}{7*4}=\frac{49}{28}[/tex] )

Now that we have all the same denominators, just add them/combine them.

[tex]-\frac{49}{28} -\frac{1}{28} -\frac{15}{28}[/tex] = [tex]-\frac{33}{28}[/tex]

Answer:

8 bags and 19.25$

Step-by-step explanation:

4/5÷1/10=8

1bags costs:5.50/2=2,75$=>7 bags cost: 2.75×7=19.25$

Answer:

-22

Step-by-step explanation:

it seems each point is increasing by 3. since the needed point is two behind -16 the result would be -22

(hopefully that'sright)

Answer: 4/50 equals 2/25

Step-by-step explanation:4/50 and 2/25 equal.08. To get it I did 2×2=4 and 25×2=50 to get 4/50 which equals 2/25 or .08

Answer:

.08 or 8/100

Step-by-step explanation:

First I'd change the fraction to an equivalent fraction with 100 as the denominator since we want the number in hundredths.

If you multiply 25 by 4 you get 100, so that would be the denominator.

Since you multiplied the denominator by 4 you'd also have to multiply the numerator, 2. 2 times 4 is 8.

Now your fraction is 8/100, and if you change this into decimal form, you get .08

Answer:

24

Step-by-step explanation:

There are 3 dimensions 3, 4, and 2. multiply all of these the get the volume. 3 x 4 = 12. 12 x 2 = 24

Answer:

Step-by-step explanation:

In order to solve this, you must use the volume of the cube.

[tex]\underline{\textbf{VOLUME OF THE CUBE FORMULA:}}[/tex]

[tex]\Longrightarrow: \sf{V=L*W*H}[/tex]

Multiply.

Use the order of operations.

PEMDAS stands for:

[tex]\Longrightarrow: \sf{3*2*4}[/tex]

First, do multiply.

[tex]\Rightarrow: \sf{3*2=6}\\\\\\\Rightarrow: \sf{6*4=\boxed{\sf{24}}[/tex]

I hope this helps. Let me know if you have any questions.

Answer:

[tex]\sf D.\;\;x=2[/tex]

Step-by-step explanation:

[tex]\sf 3x + 2 = 7x - 6[/tex]

Subtract 2 from both sides:-

[tex]\sf 3x+2-2=7x-6-2[/tex]

Simplify:-

[tex]\sf 3x=7x-8[/tex]

Subtract 7x from both sides:-

[tex]\sf 3x-7x=7x-8-7x[/tex]

Simplify:-

[tex]\sf -4x=-8[/tex]

Divide both sides by -4:-

[tex]\sf \dfrac{-4x}{-4}=\dfrac{-8}{-4}[/tex]

Simplify:-

Answer:

2.4h+2.2

Step-by-step explanation:

4.5h-7.7+9.9-2.1h

To solve this problem, we need to combine like terms.

Because 2.1h is negative, we can subtract it from 4.5h and get 2.4h.

2.4h-7.7+9.9.

We can do the same thing with -7.7 and 9.9. 9.9-7.7=2.2. We have to stop there because constants, numbers without variables, can't be added or subtracted to coefficients, numbers with variables.

Therefore, the simplified equation is 2.4h+2.2.

Answer:

Step-by-step explanation:

There are two ways to go about solving this problem, depending on your available time and fluency with the topic:

Solve it “properly”, by graphing the inequalities yourself, then comparing your graph to the available options.

Use the test-taking strategies of “ruling out answers that are clearly wrong”, followed by “use enough of what you know about the problem to select the correct answer.

Let’s walk through both, since you should be able to do both, as this problem looks very much like a practice problem for a standardized Algebra 1 test.

So! To graph a linear inequality, the steps include graphing the line, determining what type of line, and determining how it’s shaded, though the order of these steps is only important if you’re doing math in pen, which is a terrible idea.

The first inequality:

Step-by-step explanation:

Step 1: Recognizing that we have an isosceles triangle

This is an isosceles triangle because it has two congruent sides(two sides with a length of 7). The angles across from the congruent sides are also congruent, so the angle without a label measures x∘

x, degrees:

Hint #22 / 4

Step 2: Writing an equation

The three angles in a triangle add up to 180 180  ∘

180, degrees. We can write this as an equation:

x + x + 80 = 180∘

+x  ∘

+80  ∘

=180  ∘

x, degrees, plus, x, degrees, plus, 80, degrees, equals, 180, degrees

Hint #33 / 4

Step 3: Solving for x

x+x+80

2x+80

2x+80−80

Answer:

$86.60

Step-by-step explanation:

Method 1: 12.99 ÷ 15 × 100 = 86.6

Method 2: 12.99 ÷ 15% = 86.6

Using (15 × 100) or 15% because 100% - 85% = 15%

Answer:

39 - 35 = $4

Step-by-step explanation:

mean: 19+42+35+40+39 = 175

            175/5 = 35

add up all the cost then divide by how many numbers there are.

Median:

list the numbers from lowest to largest

19, 35, 39, 40, 42

then find the number in middle

39

last: 39-35=$4
