Answer:
-1 = s
Step-by-step explanation:
7 = -10s - 3
Add 3 to each side
7+3 = -10s - 3+3
10 = -10s
Divide each side by -10
10/-10 = -10s/-10
-1 = s
Silas was curious if sample minimum was an unbiased estimator of population minimum. He started with a large
normally distributed population of test scores whose minimum was 51 points.
He then took a random sample of 6 tests and calculated the minimum of the sample. He replaced those tests
and repeated this process for a total of 40 trials. His results are summarized in the dotplot below, where each
dot represents the minimum score from a sample of 6 tests.

Sample minimum
Answer:
Sample minimum appears to be a biased estimator since it consistently overestimated the population minimum.

The angles shown are supplementary.
What is the value of x?
Answer:
x = 35
Step-by-step explanation:
Answer:
x = 35
Step-by-step explanation:
Remember: The measures of supplementary angles add up to 180
In your case
3x + 15 + 60 = 180
3x + 75 = 180
3x = 105
x = 35

[tex](x + y) ^{2} [/tex]
Answer:
Step-by-step explanation:
(x + y) 2
x2 + 2xy + y2
Answer:
Step-by-step explanation:
This is an example of "the square of a binomial." There is a formula for such cases;
(a + b)^2 = a^2 + 2ab + b^2 (worth memorizing)
Thus, our (x + y)^2 = x^2 + 2xy + y^2

The Becks buy a plastic tarp to cover their firewood. A rectangle that is eight and one-third yards long and six and three-fourths yards wide. Part A Which equation models the best estimate for the area of the tarp?
Answer:
56 1/4 yards
Step-by-step explanation:
Area of the tarp = length × width
Length = 8 1/3 yards
Width = 6 3/4 yards
Area of the tarp = length × width
= 8 1/3 yards × 6 3/4 yards
= 25/3 × 27/4
= (25 * 27) / (3 * 4)
= 675 / 12
= 56 1/4 yards
Area of the tarp = 56 1/4 yards

Write the standard form of the equation of the line through the given point with the given slope. point (-1.0); slope -2/3
Answer:
Step-by-step explanation:
When given a point and a slope, the best equation to use is the point-slope formula, y - k = m(x - h)
which here becomes:
y - 0 = m(x + 1), or y = (-2/3)(x + 1), or y = (-2/3)x - 2/3
If you want this in standard form, first clear the fractions by multiplying all terms by 3: 3y = -2x - 2
Now add 2x to both sides, obtaining: 2x + 3y = -2 (in "standard form."

Find missing side lengths
Answer:
Y=75 x=75
Step-by-step explanation:
This is a scalene triangle and the total of the degrees will always be 180. So 180-30=150
since there are two sides split 150 in 2. 150 divided by 2 = 75

The graph shown here is the graph of which of the following rational
functions
O A FO) = 2-3x+3
OB. AB) = x= 1962–31x-3
x-2
O C. FX) =
Given:
The graph of rational function.
To find:
The rational function.
Solution:
If the graph of a rational function has a vertical asymptote at [tex]x=a[/tex], then [tex](x-a)[/tex] must be a factor of the denominator of that rational function.
From the given graph it is clear that the graph has two vertical asymptotes. One is at [tex]x=-1[/tex] and another one is at [tex]x=3[/tex].
It means, [tex](x-3)[/tex] and [tex](x+1)[/tex] are the only two factors of the denominator of the rational function.
In option A, the factors of the denominator are different from [tex](x-3)[/tex] and [tex](x+1)[/tex] .
In option B, the denominator has an extra factor [tex]x-2[/tex].
In option C, the denominator has only two factors [tex](x-3)[/tex] and [tex](x+1)[/tex].
Therefore, the correct option is C.
Alejandro and Noya were told to draw a net for an octagonal prism. Which statement about the students' nets is true?
Complete question is;
Alejandro and Noya were told to draw a net for an octagonal prism. Which statement about the students’ nets is true? Both nets do not form octagonal prisms.
A) Only Alejandro’s net is correct.
B) Only Noya’s net is correct.
C) Neither net is correct.
D) Both nets are correct.
Answer:
C) Neither net is correct.
Step-by-step explanation:
From the second attached image, we can see what an octagonal prism looks like when it is opened to show all the faces.
However, looking at the first attached image showing the net drawings of boya and Alejandro, it is very clear that none of them got the required shape for the octagonal prism. Therefore, we can conclude that neither of the nets are correct.

McKenna was asked to write the following expression in standard form.
3−5(3a+6)
When writing the expression in standard from, McKenna made a mistake.
3−5(3a+6)
3+(−5)(3a+6) Step 1
−2(3a+6) Step 2
−6a+(−12) Step 3
−6a−12 Step 4
a. McKenna made her first mistake in ____________
Question 2
b. The correct expression in standard form is ______
basically pls fill in the blanks :]
Answer: -15a - 27
Step-by-step explanation:
McKenna made her first mistake in Step 2. You would need to multiply -5 by 3a and 6, not add it to 3 first.
The correct steps would be:
3−5(3a+6)
3+(−5)(3a+6) Step 1
3 - 15a - 30 Step 2
-15a - 27 Step 3
