Answer:
we know that
Victoria has $125 to spend
[purchase price skateboard]=$139.99-0.15*$139.99-----> $139.99-$21
[purchase price skateboard]=$118.99
sales tax is 7%----------> 0.07*$118.99----------> $8.33
sales tax is $8.33
Victoria has to pay [$118.99]+[$8.33]=$127.32
$127.32 > $125
therefore
Victoria has not enough money to buy the skateboard
the answer is
Victoria has not enough money to buy the skateboard

The following sequence is an arithmetic sequence. [-9, -2, 5, 12,...]
Find the common difference and the next two terms.
Answer: The common difference is 7, and the next two terms are 19 and 26.
Step-by-step explanation:
Between -9 and -2 there is +7, same with between -2 and 5, as well as 5 and 12. Adding 7 to 12 again gets 19, and adding 7 to 19 gets 26 as well for the next two terms.

A bag contains cards numbered from 10 to 100. Why are the events "choosing an odd number" and "choosing an even number" mutually exclusive?
A) a number is neither even nor odd
B) they are dependent
C) they are independent
D) a number is either even or odd
The reason why the events "choosing an odd number" and "choosing an even number" are mutually exclusive is; Choice D; a number is either even or odd.
What are Mutually exclusive events in probability?It follows from probability theory, that two events are characterized as mutually exclusive if they cannot both occur at the same time. A very good example is the set of outcomes of a single die roll, which can result in any of the 6 outcomes.

To minimize the probability that he incorrectly rejects the null hypothesis, David must change the (d) the significance level of the test
How to determine the true statement?The sample size is given as:
n = 40
From the question, we understand that the sample size cannot be changed
This means that the standard deviation, and the mean cannot be altered too.
Since the value of the significance level is not constant, David can decide to adjust the significance level.

A straw is placed inside a rectangular box that is 3 inches by 5 inches by 1 inches, as
shown. If the straw fits exactly into the box diagonally from the bottom left corner to
the top right back corner, how long is the straw? Leave your answer in simplest
radical form.
The length of the straw will be 5.91607 inches long in radical form.
What is Length of diagonal in cuboid?If a cuboid has length = l units, breadth = b units, and height = h units, then we can evaluate the length of the diagonal of a cuboid using the formula
[tex]X^{2}= l^{2}+b^{2}+h^{2}[/tex]
As per the question the length of the straw is equal to length of the diagonal of Rectangular box.
l= 3 inch , b= 5 inch , h= 1 inch
Let us consider the length of the straw be 'x'.
As, Diagonal of Cuboid is,
[tex]X^{2}= l^{2}+b^{2}+h^{2}[/tex]
[tex]X^{2}= 3^{2}+5^{2}+1^{2}\\X^{2}= 9+25+1\\X^{2}= 35\\X= \sqrt{35}[/tex]
X= 5.91607 (in radical form)
Hence, the length of the straw will be 5.91607 inches.

Given the relation: {(1,2),(2,3),(-1,3),(2,5)}
Determine what two points cause the relation to not be a function? Explain why these points cause the relation to not be a function.
Answer: (2,3) and (2,5) cause the relation to not be a function
Explanation:
The input x = 2 leads to y = 3 and y = 5 at the same time for both points. A function is where any input x leads to exactly one y output only. So we'd need to get rid of one of those mentioned points to be able to have a function.
If you graphed the points on the same xy grid, then you'd see (2,3) and (2,5) vertically aligned. These two points cause the vertical line test to fail. This will give a visual indication we do not have a function.
Put another way, if x repeats itself then we don't have a function. The y value is allowed to repeat. So we could have something like (1,2) and (5,2) be part of a function.

In an experiment, 16 babies were asked to watch a climber attempt to ascend a hill. On two occasions, the baby witnesses the climber fail to make the climb. Then, the baby
witnesses either a helper toy push the climber up the hill, or a hinderer toy preventing the climber from making the ascent. The toys were shown to each baby in a random
fashion. A second part of this experiment showed the climber approach the helper toy, which is not a surprising action, and then the climber approached the hinderer toy,
which is a surprising action. The amount of time the baby watched the event was recorded. The mean difference in time spent watching the climber approach the hinderer
toy versus watching the climber approach the helper toy was 1.22 seconds with a standard deviation of 1.58 seconds. Complete parts a through c.

you need to make 6000g of potato cakes. the ratio of potato, cheese and onion is 9:2:1. per every 175g of cheese = £2.25. how much will all of the cheese cost?
Let
potato be 9x,cheese be 2x and onion be x
9x+2x+x=600012x=6000x=500Cheese
2(500)1000gTotal 175gs
100/1755.714Total cost
5.714(2.25)£12.85Answer:
£12.86 (nearest pence)
Step-by-step explanation:
Given ratio:
potato : cheese : onion = 9 : 2 : 1Sum the ratios:
⇒ 9 + 2 + 1 = 12
Divide the total weight by the sum of the ratios:
⇒ 6000 g ÷ 12 = 500
Multiply each ratio by 500 to find the amount of each ingredient needed to make 6000 g of potato cakes:
⇒ potato = 9 × 500 = 4500 g
⇒ cheese = 2 × 500 = 1000 g
⇒ onion = 1 × 500 = 500 g
If 175 g of cheese costs £2.25, then 1000 g of cheese costs:
⇒ (2.25 / 175) × 1000 = £12.86 (nearest pence)
