Answer:
6.50 + 5.75n
Step-by-step explanation:
6.50 for the first hour only being charged once and the 5.75 being for the number of hours (n) she works after the first hour
Answer:
B
Step-by-step explanation:
n is how many additional hours after the first hour she babysits. She charges $5.75 for each additional hour. So, that would be:
5.75n
But for the first hour, she charges 6.50. So that would be:
6.50+5.75n
The probability that Gerald makes a three-point shot in basketball is 20\%20%20, percent. For practice, Gerald will regularly shoot a series of these shots until he succeeds at one. He's curious how many shots it will typically take him to get his first successful shot.
He simulated 404040 trials of three-point shots where each shot had a 0.20.20, point, 2 probability of being successful, and in each trial, he counted how many shots it took to get the first successful shot. Here are his results:
Use his results to estimate the probability that it takes 101010 or fewer shots to get his first successful shot.
Give your answer as either a fraction or a decimal.
Answer:
[tex]P(x \le 10) = 0.85[/tex]
Step-by-step explanation:
Given
See attachment for properly presented question
Required
[tex]P(x \le 10)[/tex]
From the question, we understand that he takes 40 shots (trials)
So:
[tex]n = 40[/tex]
From the attached plot, the number of attempts up to the 10th is:
[tex]x \le 10 = 9+6+5+4+4+2+2+0+1+1[/tex]
[tex]x \le 10 = 34[/tex]
So, we have:
[tex]P(x \le 10) = \frac{n(x \le 10)}{n}[/tex]
[tex]P(x \le 10) = \frac{34}{40}[/tex]
[tex]P(x \le 10) = 0.85[/tex]

Answer:
Angle A
Step-by-step explanation:
Remember:
SOH CAH TOA
Opposite = Directly across from.
Adjacent = Next to.
Hypotenuse = Longest side.
Tangent = Opposite Side / Adjacent Side.
✓ Tan A = 6 / 8 = 3 / 4 = 3 / 4
× Tan B = 8 / 6 = 4 / 3 ≠ 3 / 4
× Tan C = 10 / 8 = 5 / 4 ≠ 3 / 4

here, we have,
Given:
Luisa Díaz drove her vehicle about 7,200 miles last year.
Total fixed cost = $1,058.40
Total variable cost = $1965.60
Question asked:
How much did it cost per mile ?
Solution:
Total cost of driving 7200 miles = Total fixed cost + Total variable cost
= $1,058.40 + $1965.60
= $3024
By unitary method:
Cost of driving 7200 miles = $3024
Cost of driving 1 mile = $3024 7200
= $0.42
Thus, cost of driving per mile is $0.42

4. Find the value of x in the given parallelogram.
(2x+5)*
1159
Your answer
Answer:
x = 55
Step-by-step explanation:
Use the property of a parallelogram,
" Opposite interior angles of a parallelogram are equal in measure"
By this property, opposite angles given in the figure will be equal.
(2x + 5)° = 115°
2x = 115 - 5
2x = 110
x = [tex]\frac{110}{2}[/tex]
x = 55
Therefore, x = 55 will be the value.

Johann borrows money from his parents to purchase a bike. He makes weekly payments to his parents to repay the money
borrowed. The total amount of money repaid at the end of week n can be represented using the recursive formula a, = 10+ an-1-
At the end of the fourth week, Johann had repaid his parents a total of $55. What is the total amount Johann had repaid his
parents at the end of the first week?
o $10
$20
$25
$35
Answer:
$25
Step-by-step explanation:
An = 10 + An-1
At the end of 4th week ; amount repaid = $55
A4 = 10 +
An = a + (n - 1)d
n = 4
A4 = 10 + (4 - 1)d
55 = 10 + 3d
55 - 10 = 3d
45 = 3d
d = 15
Hence, at the end of first week :
A1 = a + d
$10 + $15
= $25

Answer:
5/16 pounds
Step-by-step explanation:
The problem mentions that Audrey needs to cut a 5-pound block into 16 pieces. This means that each of the 16 pieces of cheese must weigh the same, thus we have to divide 5 pounds by 16 to divide the weight equally. Thus, all you need to do is divide 5 by 16, giving you 5/16. Therefore, your answer is that each block of cheese weighs 5/16 pounds.
Answer:
0.3125 pounds
Step-by-step explanation:
Each wedge of cheese weights 0.1325 pounds

Find the median of the data in the box plot below. Cookies A horizontal boxplot titled Number of cookies eaten by each contestant, is plotted along a horizontal axis marked from 2 to 30, in increments of 1. A left whisker extends from 5 to 6. The box extends from 6 to 22 and is divided into 2 parts by a vertical line segment at 8. The right whisker extends from 22 to 25. All values estimated.
Diagrammatic representation of the summarized box plot is attached below :
Answer:
Range = 20
Median = 8
Step-by-step explanation:
The median value of a box plot is obtained at the point where a vertical line divides the box into two parts. In the boxplot Given the median of the representation is 8. This is the point where the vertical line divides the box.
The range of the distribution is the difference between the maximum and minimum value :
Minimum (starting point of whisker) = 5
Maximum (end point of whisker) = 25
Range = 25 - 5 = 20
A triangular piece of wood is being installed on a front porch. The piece of wood is shown below. Find its area. Round to the nearest tenths place.
Answer:

In tilton school there are 380 students in key stage 3 240 students in key stage 4 110 students in key stage 5 phoebe is carrying out a survey. she needs a sample of 100 students
Answer:
52
Step-by-step explanation:
Total Number of students :
Stage 3 : 380
Stage 4 : 240
Stage 5 : 110
Total = (380 + 240 + 110) = 730
Number of samples required = 100
Number of key stage 3 students required :
(Key stage 3 / total) * number of samples
(380 / 730) * 100
= 0.5205479 * 100
= 52.0547
= 52
Sixty percent of the people surveyed use sunscreen. A random number generator was used to simulate the results of asking the next three people. The numbers 0–5 represent people who use sunscreen, and the numbers 6–9 represent people who do not use sunscreen. What is the probability that two of the next three respondents use sunscreen?
Answer:
[tex]Pr = 0.50[/tex]
Step-by-step explanation:
Given
See attachment for complete question
Required
Probability that 2 of 3 use sunscreen
From the attached data, we have:
[tex]S = \{275, 738, 419, 582, 987, 436, 578, 472, 178, 839\}[/tex]
[tex]n(S) = 10[/tex]
Events where 2 of the 3 uses sunscreen is:
[tex]x = \{275, 419, 582, 436, 472\}[/tex] --- i.e. where 0 -5 represents sunscreen
[tex]n(x) = 5[/tex]
So, the required probability is:
[tex]Pr = \frac{n(x)}{n(S)}[/tex]
[tex]Pr = \frac{5}{10}[/tex]
[tex]Pr = 0.50[/tex]
Write the equation of a line with a slope of 2/3 going through the point (-15, -22)
Answer:
y=(2/3)(x+15)-22
Step-by-step explanation:
You use the slope point equation which is y-y1=m(x-x1) or y=m(x-x1)+y1 where m is the slope and x1 and y1 are the coordinates you plug in.
Therefore, 2/3 is the slope m and (-15, -22) are the coordinates for x1 and y1.
y=(2/3)(x-(-15)) + (-22)
y=(2/3)(x+15)-22
