Answer:
4/5
Step-by-step explanation:
To find the rate of change, you are finding the slope of the chart.
Using the equation, △y/△x can be rewritten as [tex]\frac{y2-y1}{x2-x1}[/tex].
Plug in 2 coordinate points in the chart to find the rate of change.
[tex]\frac{8-4}{10-5} =\frac{4}{5}[/tex]
The rate of change is 4/5.

Answers
Answer:
expanded for everything
Step-by-step explanation:
Expanded Form of 531.029:
531.029 = (5 * 102) + (3 * 101) + (1 * 100) + (2 * 1/102) + (9 * 1/103)
531.029 = (5 * 100) + (3 * 10) + (1 * 1) + (2 * 1/100) + (9 * 1/1,000)
531.029 = 500 + 30 + 1 + 2/100 + 9/1,000
531.029 = 500 + 30 + 1 + 0.02 + 0.009

To solve this we need to use order of operations, also known as pemdas
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
You do that in order.
So first solve what in the parentheses,
8 divided by 2 is 4
So now we have
24 - 4 + 6
I know addition is written first in PEMDAS but you’re supposed do go left to right when that’s all you have left.
So
24 - 4 = 20
And
20 + 6 = 26

Tom is applying for a visa.
He has to pay £2,400 for the visa as well as a 8% charge on the visa price for an on-the-day service.
If Tom has 1 year to save, how much money should he save per month to be able to cover his costs?
Round your answer to the nearest £10.
Answers
Answer:
100
Step-by-step explanation:
The total amount Tom saved per month is equal to [tex]\£ 220[/tex] (nearest [tex]\£10[/tex]).
What is the amount?" Amount is defined as the total of all the given quantities as per given conditions."
According to the question,
The amount required to pay for a visa [tex]= \£ 2,400[/tex]
Percentage charges on the visa price as day service[tex]= 8\%[/tex]
Amount as day charge [tex]= 8\%[/tex] of [tex]2400[/tex]
[tex]= \frac{8}{100} \times 2400\\\\= \£192[/tex]
The total amount required for a visa [tex]= \£ (2400 + 192)[/tex]
[tex]= \£ 2592[/tex]
Tom has one year to save,
Therefore,
Amount Tom save in one month [tex]= \frac{2592}{12}[/tex]
[tex]=\£ 216[/tex]
≈[tex]\£ 220[/tex] ( round to nearest [tex]\£ 10[/tex])
Hence, the total amount Tom saved per month is equal to [tex]\£ 220[/tex] (nearest [tex]\£10[/tex]).

The Balina can travel at a rate of ______________ miles per hour (mph).
Answers
Answer:
The Balina is faster than the Delfino.
Step-by-step explanation:
Divide the amount of miles covered by the amount of hours it took for each one.
For the Delfino:
57.5 / 5 = 11.5
For the Balina:
54 / 4.5 = 12

a) The null hypothesis is: p = 0.8 and the alternative hypothesis is p ≠ 0.8.
b) p-value is 0.0838
c) We accept the null hypothesis
What are null and alternative hypothesis?The null hypothesis of a test always predicts no effect or no relationship between variables, while the alternative hypothesis states your research prediction of an effect or relationship.
What is p-value?A p-value is a statistical measurement used to validate a hypothesis against observed data.
a. Let p be the proportion of 8 out of 10 dentists.
The null hypothesis is
[tex]H_0 : p=\frac{8}{10}=0.8[/tex]
The alternative hypothesis is
[tex]H_1:p\neq 0.8[/tex]
b. The sample proportion [tex]\hat p=\frac{73}{85}\approx 0.86\\[/tex]
Z-score, the test statistic is
[tex]Z=\frac{\hat p-p}{\frac{\sqrt{p(1-p)}}{n} } \\\\Z=\frac{0.86-0.8}{\frac{\sqrt{0.8(1-0.8)}}{85} }\\ \\Z=\frac{0.06}{0.043386}\\ \\Z=1.3829\\\\Z\approx 1.38[/tex]
P(Z > 1.38) = 1 - P(Z < 1.38)
∴ P(Z > 1.38) = 1 - 0.9162 = 0.0838
p-value is 0.0838
c. Since the p-value is greater than the level of significance α=0.05, we reject the alternative hypothesis and accept the null hypothesis

One month Chris rented 7 movies and 9 video games for a total of $71. The next month he rented 5 movies and 3 video games for a total of $31. Find the rental cost for each movie and each video game.
Answers
7m+9v=$71
5m+3v=$31
multiply the whole of the second equation by three to get:
7m+9v=$71
15m+9v=$31
now subtract the second equation from the first to get: 8m=$40 so a movie costs $5
now substitute the movie back into:
7(5)+9v=$71
35+9v=$71
9v=$36
so a video game costs $4
