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.

Part of the population of 6,750 elk at a wildlife preserve is infected with a parasite. A random sample of 50 elk shows that 9 of them are infected. How many elk are likely to be infected?
When the sample is given, the number of elk are likely to be infected is to be considered as the 1,215.
Calculation of the number of elk:Since the population is 6,750.

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.

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.

Explanation:
Given a right angle triangle, In order to find the third side: Use Pythagoras Theorem: a² + b² = c²
Insert values:
x² + 8.9² = 11.5²
x² + 79.21 = 132.25
x² = 132.25 - 79.21 (subtract)
x² = 53.04
x = √53.04 (square root)
x = 7.28285 ≈ 7.3 (rounded to 1 decimal place)
11.5 cm
8.9 cm
to find:the unknown value "x"
solution:we'll have to use pythagoras theorem.
unknown value is x

To solve 1/4÷8, Jordan thinks of dividing a pancake into 4 equal parts, dividing one of those parts into 8 equal pieces, and then eating one of those pieces.
What fraction of the pancake is Jordan thinking about eating?
Enter your answer as a fraction in simplest form by filling in the boxes
Answer: 1/32
Step-by-step explanation:
1st step: 1/4 divided by 8, which is 1/4 divided by 8/1
Then for the 2nd step, you have to find the reciprocal of the 2nd fraction, so you just reverse it
2nd step: 1/4 X 1/8
3rd step. 1X1/4X8 = 1/32
You can also think of it like this. He started with 4 pieces. Each piece was then divided into 8 parts. So 8X4=32 is the total number of pieces. He's only eating 1 of those, so he's only eating 1/32.
Answer:
1/32
Step-by-step explanation:
[tex]\displaystyle \frac{\frac{1}{4}}{8}=\frac{1}{4*8}=\frac{1}{32}[/tex]

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.
