Answer:
79 degrees.
Step-by-step explanation:
There are 7 total temperatures, 68, 82, 81, 82, 74, 75, and 91 degrees. To find the mean, we add all of the temperatures together and divide it by the number of tempuratures-- 7.
68+82+81+82+74+75+91 = 553.
553 / 7 = 79.
Hope this helps!

The first term of an arithmetic sequence is -140 and the 90th term is 483. What is the value of the 55th term?
Answers
Answer: 238
Step-by-step explanation:
The formula to calculate the nth term of an arithmetic progression = a + (n-1)d
Based on the question,
a = -140
90th term = a + 89d = 483
We need to get the value of the common difference
a + 89d = 483
-140 + 89d = 483
89d = 483 + 140
89d = 623
d = 623/89
d = 7
Therefore 55term will be:
= a + (n - 1)d
= a + (55 - 1)d
= a + 54d
= -140 + 54(7)
= -140 + 378
= 238

Option 3
Step-by-step explanation:
The sentence provides the reasoning for a possible explanation.
Now, let's look at all the possible answers:
1. This doesn't show us that scientists cannot agree. A sentence like that could be that many scientists have analyzed the region, but they did not find anything.
2. This does not tell us that this region is interesting. A sentence like that would be saying that the cause of the lightning is unknown.
3. This is correct- it provides evidence for a main theory.
4. This does not explain why people name the lightning a certain way. A sentence like that could be a local fable.
One study, based on responses from 1,017 randomly selected teenagers, concluded that 39% of teenagers cite grades as their greatest source of pressure. use a 0.05 significance level to test the claim that fewer than half of all teenagers in the population feel grades are their greatest source of pressure
Answers
Answer:
The hypothesis formulae will be
H0 : p = 0.5
Ha : p < 0.5
we will reject H0.
Step-by-step explanation:
Number of responses ( n ) = 1017
percentage( p ) = 39% = 0.39
significance level ( ∝ ) = 0.05
P0 = 50% = 0.5
Test the claim that fewer than half of all teenagers feel the pressure
The hypothesis formulae will be
H0 : p = 0.5
Ha : p < 0.5
Perform the test statistic
Test statistic ( Z ) = -6.957
P-value < 0.05 we will reject H0.
Eunice wanted to save up for a mountain bike that costs £250. She baby-sits each week for 6 hours for £2.75 an hour, and does a Saturday job that pays £27.50. She saves 3/4 of her weekly earnings. How many weeks will it take her to save enough to buy the bike?
Answers
Answer:
Approximately 2 weeks
Step-by-step explanation:
Given data
Cost of bike= £250
Assuming she works for 6 days
1.Babysitting
6*2.75=£16.5 per day
for 6 days
=16.5*6
=£99
2. Saturday Job
=£27.50
Total earnings for the week
=£27.50+£99
=£126.5 weekly
Hence it will take her
=250/126.5
=1.97 week
Approximately 2 weeks to save up the amount

Benjamin rode tghe train for 45 minutes. Then it took him another 30 minutes to walk to his friend's house. How many hours did he spend riding and walking to his friend's house?
Answers
Answer:
1.25 hours
Step-by-step explanation:
Benjamin rode tghe train for 45 minutes. Then it took him another 30 minutes to walk to his friend's house. How many hours did he spend riding and walking to his friend's house?
The number of hours he spent riding and walking to his friends house is calculated as:
45 minutes + 30 minutes
= 75 minutes
Converting this to hours
60 minutes = 1 hour
75 minutes = x
Cross Multiply
60 × x = 75 × 1
x = 75/60
x = 1.25 hours

The angle measurements in the diagram are represented by the following expressions.
Answers
Answer:
x = 20 , ∠ A = 125°
Step-by-step explanation:
∠ A and ∠ B are alternate angles and are congruent, then
6x + 5 = 4x + 45 ( subtract 4x from both sides )
2x + 5 = 45 ( subtract 5 from both sides )
2x = 40 ( divide both sides by 2 )
x = 20
Then
∠ A = 6x + 5 = 6(20) + 5 = 120 + 5 = 125°

(1, 4), because the point does not lie on any axis
(1, 4), because one of the lines passes through this point
(1, 4), because both lines pass through this point
(1, 4), because the point lies between the two axes
Answers
Answer:
The answer is (1,4) because both lines pass through this point.
Step-by-step explanation:
To find a solution to a system of equations, both lines have to pass through the same point. If both lines intercept at the same point, that means that point is the solution to the system of equations.
Evaluate the algebraic expression 4v-3 if v= -5.explain
Answers
Answer:
-23
Step-by-step explanation:
Given 4v-3
evaluate when v = -5
So basically we want to find the value of the expression when the variable (v) equals -5
so
* plug in -5 for v*
4(-5)-3
4*-5=-20
-20-3=-23
So we can conclude that when v = -5 the value of the expression is -23
Answer:
4v-3 = -23Explanation:
given the expression: 4v-3
if v = -5
4v-3 (let's subsitute v)
4v-3 = 4×(-5)-3
4v-3 = -20 - 3
4v-3 = -23
