Answers

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

16
2+3+5+9+17+22+31+39=128
128/8=16

Answer:

x = 10

The shaded angles are each 31 degrees.

Step-by-step explanation:

I don't know if you are being asked to solve for x or the shaded angle, so we'll solve for both.

Those 2 shaded angles are equal to each other. So set them equal to each other & solve for x.

91-6x = 4x-9

91+9 = 4x+6x

100 = 10x

10 = x

Now substitute x=10 to find the measure of the shaded angles (which are equal).

91-6x = 91-6(10) = 91-60=31

The shaded angles are both 31 degrees .

How far did I travel to reach my destination on each day of my three-day Trip? a. On Day 1, after traveling 5/8 of the way to the first day's destination, I still had 15 miles left to go before reaching my first destination. b. On Day 2, after traveling 18 miles, I still had 2/5 of that day's distance left to go before reaching my second destination. c. On Day 3, after traveling 5/11 of that day's distance, I still had 6 more miles to travel than what I had already traveled that day, before reaching my third destination.

Answers

Answer: 81 miles

Step-by-step explanation:

The total distance traveled on the three-day trip is: 81 miles.

How did we get the value?

Denote the total distance of each day's journey by D1, D2, and D3, respectively. Then write equations based on the given identities:

a. (5/8)D1 + 15 = D1

(3/8)D1 = 15

D1 = 40 miles

So, the total distance traveled on Day 1 is 40 miles.

b. 18 + (2/5)D2 = D2

(3/5)D2 = 18

D2 = 30 miles

So, the total distance traveled on Day 2 is 30 miles.

c. (5/11)D3 + 6 = D3

(6/11)D3 = 6

D3 = 11 miles

So, the total distance traveled on Day 3 is 11 miles.

Therefore, the total distance traveled on the three-day trip is:

40 + 30 + 11 = 81 miles.

Answer:

Step-by-step explanation: don't know

M= -1

Explanation:
Step 1: bring -8 to the left since it is less than 10. It would now be 18+8m= -10.

Step 2: you would then move 8 to the right side since you want them to be equal on both sides. it would now be 18= -18m

Step 3: Finally, you divide -18 since you want to find m;you would need to separate them

Answer is m= -1

Answer:

Answer for Number 1: 54 1/2

Answer for Number 4: $2.36

Step-by-step explanation:

Explanation for number 1:

    1.  length x width = area right? So area divided by length = width!

        159 3/8 divided by 18 3/4 = 8 1/2

    2. width + width + length + length = perimeter right? Now you know the

        width,  you can do...

         8 1/2 + 8 1/2 + 18 3/4 + 18 3/4 = 54 1/2

Explanation for number 4:

    1.  You know that 4 cup = 1 quart right?

        9.44 = 1 quart

    2. So you divide it:

        9.44 / 4 = $2.36

Answer:

6(x + 4) = 5

Step-by-step explanation:

We can break this sentence down into individual operations:

"six times" → this means 6 multiplied by some quantity

6 · ()

"the sum of a number and 4" → this is the quantity that we can put inside the parentheses (Note that "a number" is represented as a variable x, and a "sum" is the result of the addition of multiple numbers.)

6 · (x + 4)

"equals 5" → this is self-explanatory; the expression above is equal to 5

6(x + 4) = 5

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

Note that multiplication with a value inside parentheses is implied.

For example,

4(5) = 4 · 5 = 20

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

We can solve for x in this equation to solve for "a number".

6(x + 4) = 5

↓ applying the distributive property ... a(b + c) = (a · b) + (a · c)

6x + (6 · 4) = 5

↓ simplifying

6x + 24 = 5

↓ subtracting 24 from both sides

6x = -19

↓ dividing both sides by 6

x = -19/6

6(x+4)=5, the 6 multiplies a number which will be X and four which equals five

The organized list shows all the possible outcomes of an experiment in which three fair coins are flipped. The possible outcomes of each flip are heads​ (H) and tails​ (T).

Sample Space: HHH HHT HTH HTT THH THT TTH TTT

What is the probability that exactly 3 fair coins land heads up when 3 are flipped?

The probability is?

Type an integer or a fraction.

Answers

To find the probability of getting exactly 3 heads when 3 fair coins are flipped, we need to determine the number of favorable outcomes (outcomes with 3 heads) and divide it by the total number of possible outcomes.

From the sample space given, we can see that there is only one outcome with 3 heads: HHH.

The total number of possible outcomes is 2^3 = 8, as each coin can land in either heads or tails, and there are 3 coins.

Therefore, the probability of getting exactly 3 heads when 3 fair coins are flipped is 1/8.

Answer:To write the number 0.0000149 in scientific notation, we need to express it as a number between 1 and 10 multiplied by a power of 10.

First, we move the decimal point to the right until there is only one non-zero digit to the left of the decimal point, which gives us:

1.49 × 10^-5

Since we moved the decimal point 5 places to the right, the exponent of 10 is negative 5.

Therefore, the scientific notation of 0.0000149 is 1.49 × 10^-5.

Step-by-step explanation:

Answer:

1.49×10^-5

Step-by-step explanation: Isolate S by timesing it by 2, which means you have to times A and 3 by two and take S to the other side of the equation which makes the minus into a plus.

Answer:

[tex]S=\frac{A+3}{2}[/tex]

Step-by-step explanation:

The original equation is:

A=2S-3

But, we are now solving for S, so we have to isolate S.

To do this, we first must add 3 to both sides:

A+3=2S

Next, divide both sides by 2:

[tex]\frac{A+3}{2}=S[/tex]
