Nick climbed a hill with an elevation of feet. Later that day, he returned home descending 700 feet. Jacob deposited his paycheck of $ . Later that week, he withdrew the same amount of $225 to buy a new TV. Janine was scuba diving and dove 25 feet to look at the fish on the coral reef. She then swam feet to the surface. The temperature started at -25 degrees. During the day, the temperature rose 5 degrees and then dropped 5 degrees. At the end of the day, the temperature was degrees.
Answer:
700, 225, 25, -25
Step-by-step explanation:
In the question given, we have to fill the blanks in the situations to describe an opposite quantities which combines to make zero.
1. Nick returned home descending 700 feet later at the day because he climbed a hill that was 700 feet high.
2. Jack deposited an amount of $225 in his account but later that week, he bought a new TV by withdrawing the amount of $225 from his account.
3. Janine dove into the sea to look at the coral reefs to a depth of 25 feet, and then she swam back to the sea surface by swimming 25 feet upwards.
4. The final temperature at the end of the day was -25 degrees, as the morning temperature was -25 degrees and then at daytime, it rose for 5 degrees and then again dropped by 5 degrees.

The burning time of a very large candle is normally distributed with mean of 2500 hours and standard deviation of 20 hours. Find the z-score thay correspondes to a lifespan of 2470 hours. A. 2.5 B.1.5 C.-1.5 D-2.4
Answer: C.-1.5
Step-by-step explanation:
Given: The burning time of a very large candle is normally distributed with mean[tex](\mu)[/tex] of 2500 hours and standard deviation[tex](\sigma)[/tex] of 20 hours.
Let X be a random variable that represent the burning time of a very large candle.
Formula: [tex]Z=\dfrac{X-\mu}{\sigma}[/tex]
For X = 2470
[tex]Z=\dfrac{2470-2500}{20}\\\\\Rightarrow\ Z=\dfrac{-30}{20}\\\\\Rightarrow\ Z=\dfrac{-3}{2}\\\\\Rightarrow\ Z=-1.5[/tex]
So, the z-score they corresponds to a lifespan of 2470 hours. =-1.5
Hence, the correct option is C.-1.5.

Eli wants to purchase some new school supplies. He wants to buy a calculator that costs $24 and some notebooks for school. Each notebook costs $2. Eli only has $37 to spend.
Let n represent the number of notebooks that Eli buys.
Which inequality describes this scenario?
37 Greater than or equal to 2n+24
37 < 2n+24
37 > 2n+24
37 Less than or equal to 2n+24
The inequality that models the scenario is the first one:
$24 + $2*n ≤ $37
Solving that we conclude that Eli can buy at most 6 notebooks.
Which inequality describes this scenario?
We know that Eli wants to buy a calculator that costs $24 and some notebooks, such that each notebook costs $2.
Then If Eli buys the calculator and n notebooks the total cost will be:
$24 + $2*n
We know that Eli has a total of $37 to spend, so that is the maximum amount he can spend. Thus, we can write the inequality:
$24 + $2*n ≤ $37
So the correct option is the first one.
Now also let's solve the inequality for n.
$24 + $2*n ≤ $37
$2*n ≤ $37 - $24
$2*n ≤ $13.
n ≤ $13/$2
n ≤ 6.5
So Eli can buy at most 6 notebooks.

2 feet per year
Step-by-step explanation:
I think you meant 38 1/2
and 5 1/2

18. what is the midpoint of PQ P(-2, 2.5), Q(1.4, 4)
Mid point of the points PQ is (₋0.3 , 3.25)
Given points are:
P(₋2 , 2.5)
Q(1.4 , 4)
midpoint of PQ = ?
A location in the middle of a line connecting two points is referred to as the midpoint. The midpoint of a line is located between the two reference points, which are its endpoints. The line that connects these two places is split in half equally at the halfway.
The midpoint calculation is the same as averaging two numbers. As a result, by adding any two integers together and dividing by two, you may find the midpoint between them.
Midpoint formula (x,y) = (x₁ ₊ x₂/2 , y₁ ₊ y₂/2)
we have two points:
P(₋2,2.5) = (x₁,y₁)
Q(1.4,4) = (x₂,y₂)
Midpoint = (₋2 ₊ 1.4/2 , 2.5₊4/2)
= (₋0.6/2 , 6.5/2)
= (₋0.3 , 3.25)
Hence we determined the midpoint of PQ as (₋0.3 , 3.25)

Stratified random sample would be the sampling design for the best information.
• In statistics, stratified sampling is an method of sampling from a population which can be divided into subpopulations. In surveys based on statistics, when subpopulation within an overall population var, it could be advantageous to sample each population separately.
• For example one may divide a sample of children into subgroups by age like 1-5,6-10,11-15 and above.
• The benefits of stratified sampling is that you can obtain reasonably precise estimate for subgroups related to the research.
• One disadvantage of stratified sampling is that the selection of appropriate strata for a sample of your research may be difficult.

Find the 64th term of the arithmetic sequence -4, -21, -38, ...−4,−21,−38,...
Answer:
-1075
Step-by-step explanation:
The 64th term of the arithmetic sequence -4, -21, -38, .... is -1075.
What is Arithmetic Sequence?Arithmetic sequences are a set of numbers written in an order where the difference of any two consecutive term will be a constant. This constant difference between the consecutive terms is called the common difference commonly denoted by 'd'. In other words, arithmetic sequences are formed by adding or subtracting a constant number to each term.
Arithmetic sequences are also known as arithmetic progression.
Here, the given sequence is -4, -21, -38, ...
Common difference, d = (-21) - (-4) = -21 + 4 = -17
First term, a = -4
We have to find the 64th term of this sequence.
nth term of an arithmetic progression is given by the formula,
aₙ = a + (n - 1)d
a₆₄ = -4 + [(64 - 1) × (-17)]
= -4 + [63 × (-17)]
= -4 + (-1071)
= -1075
Hence the 64th term of the arithmetic sequence -4, -21, -38, .... is got as -1075.

a) y= 7/4x+3
b) y= -7/4x+1
c) y=4/7x+7
d) y= -4/7x+4
From the option given, we can see that the equation that represents a line that is parallel to the line 7y - 4x = -49 is y=4/7x+7. Option D
The standard equation of a line is expressed as y = mx + b where
m is the slopeGiven the equation of a line expressed as 7y - 4x = -49
Make y the subject of the formula:
[tex]7y - 4x = -49\\7y=4x-49\\y=\frac{4}{7}x-\frac{49}{7}\\y= \frac{4}{7}x-7[/tex]
Hence the slope of the given line is 4/7
The equation parallel to this line will also have a slope of 4/6. Hence the correct option will be the equation with a slope of 4/7
From the option given, we can see that the equation that represents a line that is parallel to the line 7y - 4x = -49 is y=4/7x+7
