Calculate an estimate for the mean temperature
Answers
Give it the weight of the middle of the range = 11.5 for 7 times = 80.5
The temperature was in the range of 14-17 on 9 of the days.
Give it the weight of the middle of the range = 15.5 for 9 times = 139.5
The temperature was in the range of 18-21 on 16 of the days.
Give it the weight of the middle of the range = 19.5 for 16 times = 312
The temperature was in the range of 22-25 on 22 of the days.
Give it the weight of the middle of the range = 23.5 for 22 times = 517
The temperature was in the range of 26-29 on 6 of the days.
Give it the weight of the middle of the range = 27.5 for 6 times = 165
Total weight for all ranges = (80.5 + 139.5 + 312 + 517 + 165) = 1,214
Total number of days = 60
Estimated mean temperature = (1,214) / (60) = 20.23°C

23 students. Therefore there were 3 cars with only 1 student riding in each car.
The mean number of students in each car is 2. Because:
mean for 3 cars = 1
mean for 7 cars = 2
mean for 3 cars = 3
Add it all up and divide by 3 means yields 2.

a 1 = 30, a 2 = 70, a 3 = 110, a 4 = 150, a 5 = 190,...
a 2 = a 1 + d
70 = 30 + d
d = 70 - 30 = 40
a n = a 1 + ( n - 1 ) * d
For the 25th month:
a 25 = 30 + 24 * 40 = 30 + 960 = 990
Answer: B ) 990.

B.) 990
Step-by-step explanation:
Here's another way of looking at it.
Make an equation representing the graph.
y = mx + b
to find m (slope) I used points (1,30) and (4,150) to get 40 as the slope.
y = 40x + b
to solve for b (y-intercept) I plugged in any point that I wanted in the corresponding place in the equation.
using (4,150)
150 = 40 (4) + b
using PEMDAS you find that b = -10
Then plug and chug to find the number of stamps for the 25th term.
y = 40(25) + -10 or y = 40(25) - 10
y = 990

The Wilsons have triplets and another child who is 15. Since their ages all add up to 36, we can first start off with subtracting 15 from 36.
36 - 15 = 21
Now we can divide the amount we have from the rest amount of kids, since they are triplets, they are 3:
21 / 3 =

Jack bought two sweaters for $17.99 and a pair slacks for $25.50. Including a 5 1/2% tax, how much was his total purchase?
Question 5 options:
$64.86
$61.48
$52.99
$28.98
Answers
Answer:
(A) $90.23
(B) $64.86
Step-by-step explanation:
(A) Given, The cost of one skirt = $18.27
The cost of one shirt = $15.78, Then cost of two shirt = 2 × $15.78 =$ 31.56
and The cost of pair of shoes = $34.50
Thus, I have done total purchase of $18.27 + $31.56 + $34.50 = $84.33.
And, paying the tax of 7%
The total cost I spend = $84.33 × (100 + 7)% = $90.23
(B) Given, The cost of one sweater = $17.99, Then cost of two sweater = 2 × $18.27 =$ 35.98
The cost of one slack = $25.50
Thus, I have done total purchase of $35.98 + $25.50 = $61.48.
And, paying the tax of 5.5%
The total cost I spend = $61.48 × (100 + 5.5)% = $64.86
1. $90.23
2. $64.86
