Answer: the answer is 2/5 :)

The experimental probability is the probability that an event will occur based on something you found, in an experiment, etc. In this problem, you found that out of 50 times, you got tails 20 times. Therefore, the experimental probability would be 20/50, or 2/5 = 0.40 simplified.

Step-by-step explanation: I got it right on edge

Answer:

Sari did not use the greatest common factor in the equation.

Step-by-step explanation:

We have been given that the distance from Pensacola, Florida to Tallahassee, Florida on a map is 8 inches, which represents 200 miles. We are asked to find the actual distance from Pensacola to Miami if the distance on the map measures 27 inches.

We will use proportions to solve our given problem as proportion states that ratio between two proportional quantities is similar.

[tex]\frac{\text{Actual distance}}{\text{Map distance}}=\frac{200\text{ miles}}{\text{8 inches}}[/tex]

[tex]\frac{\text{Actual distance}}{\text{27 inches}}=\frac{200\text{ miles}}{\text{8 inches}}[/tex]

[tex]\frac{\text{Actual distance}}{\text{27 inches}}\times \text{27 inches}=\frac{200\text{ miles}}{\text{8 inches}}\times \text{27 inches}[/tex]

[tex]\text{Actual distance}=\frac{25\text{ miles}}{1}\times 27[/tex]

[tex]\text{Actual distance}=675\text{ miles}[/tex]

Therefore, the actual distance from Pensacola to Miami is 675 miles.

Answer:

x= 110

Step-by-step explanation:

Supplementary angles add to 180

Let x be the other angle

x +70 =180

Subtract 70 from each side

x+70-70=180-70

x = 110

Answer:

110 degrees

Step-by-step explanation:

Supplementary angles add to 180 degrees.

We have two angles: one is unknown and the other is 70 degrees.

These 2 angles added together must equal 180.

x+70=180

Since we are trying to find x, the unknown angle, we have to get x by itself. Since 70 is being added to x, subtract 70 from both sides.

x+70-70=180-70

x=110

So, the other angle is 110 degrees

Answer:

for the first question-

Answer:

98

Step-by-step explanation:

This is an arithmetic sequence

The common difference is 10-2 =8

a1 = 2

an = a1+d(n-1)

an = 2+8(n-1)

we want the 13th term

a13 = 2 +8(13-1)

      =2+ 8*12

     = 2+96

     = 98

Answer: The answer is -1/8 :)

Answer:

Your answer would be B. [tex]30[/tex]%

Step-by-step explanation:

To figure out the decrease, you would first subtract the two numbers.

[tex]1053 - 737.1 = 315.9[/tex]

Next, you would multiply the number by [tex]1053[/tex].

[tex]\frac{315.9}{1053} = .3[/tex]

Then, you would multiply that by [tex]100[/tex].

[tex].3 * 100 = 30[/tex]

The answer would be [tex]30[/tex]%.

[tex]1053 * .3 = 315.9[/tex]

[tex]1053-315.9 = 737.1[/tex]

Answer:

x (40-10) -12000≥980

The factory must sell 433 backpacks to meet its weekly goal.

Hi, to answer this question we have to write an inequality.

So, since the backpacks (x) are sold by $40 and the cost of making one is $10, the revenue per bag is equal to 40x and the cost is 10x.

12,000 of operating expenses are also expenses.

So, for the profit:

Profit = revenue- cost

P = 40x-10x-12,000

P = x (40-10)-12000

The factory goal is to make a profit of at least $980 each week, so, the profit must be greater or equal than 980.

x (40-10) -12000≥980

Solving for x

30x-12000≥980

30x≥980+12000

30x ≥12980

x≥12980/30

x≥432.6

x≥433 (rounded, because if the sell 432 they will not meet the goal)

The factory must sell 433 backpacks to meet its weekly goal.

Answer:

(A)

Step-by-step explanation:

To be honest, since all of them are different, as long as you get the first one right, you will get the others right. A is your answer, for the following reasons:

Reflexive Property: The Reflexive property states that the mirrored version of itself will always be congruent with itself. Generally, to make it easier, they will write it opposite (as they did in the given proof):

line AC ≅ line CA

~

Answer:

A

Step-by-step explanation:

AC and CA represent the same segment, therefore have the same length and hence are congruent

Last step should be CPCTC because that's what is to be proven

Answer:

First one

Step-by-step explanation:

Variable b is 7 more than variable c:

b = c + 7

Variable b is also 1 less than variable c:

b = c - 1

Answer:

B:

b = c + 7

b = c - 1

Step-by-step explanation:

"Variable b is 7 more than variable c" can be expressed mathematically as

b = c + 7

"Variable b is 1 less than variable c" can be expressed mathematically as

b = c - 1

So the second pair,

b = c + 7

b = c - 1

best models the relationship between b and c

Answer:

42%

Step-by-step explanation:

1) so out of the 50 girls surveyed, only 21 students played in the league. We can write this as 21/50

to convert this into percentage multiply by 2 on both sides:

21*2=42

50*2=100

42/100=42%

42% of girls played in the league

Step-by-step explanation:

Answer:

Step-by-step explanation:

the probability that the player will not win on Monday or Tuesday, but will win on Wednesday is the same as the probability of winning on the third trial.

This is an example of a geometric probability distribution because trials are repeated until the first success is gotten. Since chance of winning a prize on a given ticket is about 17%, it means that the probability of success, p = 17/100 = 0.17.

Let x represent the number of days before the person wins. The probability that it takes three days before the player wins is expressed as

P(x = 3)

By using the geometric distribution calculator,

P(x = 3) = 0.12
