Answer:
p = 10.5b
Step-by-step explanation:
The equation has this form:
y = ax+c
a = [tex]\frac{21-0}{2-0}[/tex] a = 21/2 a= 10.5so the slope is 10.5
c is the y-intercept wich is given by the output of 0
here it's 0
0⇒0so the equation is y = 10.5x ⇒ p=10.5b
Answer:
P=10.5b

Answer:
90
Step-by-step explanation:
-((-7) + 4 × (-12) + (-3) × 11 + (-2))
-(-7 + 4 × (-12) + (-3) × 11 + (-2))
-(-7 - 48 - 33 - 2)
-(-90) → 90
Final Answer - 90
Hope this helped! :)
Answer:
90
Step-by-step explanation:
Recall Order of Operations rules that require that computations inside parentheses must be done first. Next, multiplication be done before addition or subtraction.
-((-7) +(4)(-12)+(-3)(11)+(-2)) can be re-written as
- ((-7) +(4)(-12)+(-3)(11)+(-2)), which in turn becomes:
-( -7 - 48 - 33 - 2 ), or
-( -55 - 35), or
- (-90), or 90
With 98% confidence interval and n = 25. Find left critical value for Zinterval.
0 -2.492

Answer:
[tex]\alpha=1-0.98 =0.02[/tex]
And [tex]\alpha/2 0.01[/tex], the degrees of freedom are given by:
[tex] df= n-1= 25-1=14[/tex]
Then the critical value using the t distribution with 24 degrees of freedom is:
[tex] t_{\alpha/2}= \pm 2.492[/tex]
And the best solution would be:
0 -2.492
Step-by-step explanation:
For this problem we know that the sample size is n = 25. The confidence level is 98% or 0.98 then the significance would be:
[tex]\alpha=1-0.98 =0.02[/tex]
And [tex]\alpha/2 0.01[/tex], the degrees of freedom are given by:
[tex] df= n-1= 25-1=14[/tex]
Then the critical value using the t distribution with 24 degrees of freedom is:
[tex] t_{\alpha/2}= \pm 2.492[/tex]
And the best solution would be:
0 -2.492

The expression 14s(s - 1) can be used to find
the total number of cards created by the ninth
grade students. Based on the given information,
which of the following statements must be true?
Select all that apply.
Answer:
B. The variable s represents the number of students in each class.
C. The coefficient 14 represents the number of classes in the 9th grade.
Step-by-step explanation:
The total number can be found by multiplying the number of the things with the number of people producing it. For example if 5 boys make 5 colored ropes the total number of ropes will be 5*5= 25.
In this question the combinations rule is used for variuos number of classes which are 14. Now we have to find the number of students which are s (s-1). Suppose s= 6 so the number of students would be 6(6-1) = 6(5) = 30
We will multiply the number of classes 14 with the number of students s(s-1) to get the total number of cards produced.

Answer:
4
Step-by-step explanation:
An integer is a number that is not a decimal or a fraction.
The integers that lie between -1.25 and 2.6 are -1, 0, 1, and 2. They are all numbers with no decimal or fraction.
So, there would be 4 numbers that lie between -1.25 and 2.6.

Answer:
X = 1, 2.

Which distribution is positively skewed?
Answer:
D
Step-by-step explanation:
not positive but i think it would be D
Option C is the distributions are positively skewed.
Since, A distribution that is positively skewed would have the following highlights:
More points on the left, if represented on a dot plot
Tall bars on the left, if represented on a histogram
Whisker on the left, if represented on a box plot
The above means that none of the distributions are positively skewed.
This is so because:
A is negatively skewed because the whisker is at the right
B and C are symmetrical because there are tall bars at the middle
D is positively skewed because the whisker is at the left.
Hence, Option D is the distributions are positively skewed.

17. We need to understand what an indirect proof is. In an indirect proof, you prove a statement by showing that the negation of the statement is false.
The "then" part of the conditional is the "to prove" statement.
In an indirect proof, we assume the opposite of what we want to prove, this is also called proof by contradiction.
So if we need to prove angle A is not an obtuse angle, we will assume it is and then use the proof format to show that angle A cannot be obtuse.
The answer is B: Assume angle A is an obtuse angle18. This question is asking us to use an indirect proof again. The "then" part of the statement is "KL > JK" and is the "to prove" statement.
We need the opposite of this, which would be assuming that KL < JK.

Answer:
2.35 m²
Step-by-step explanation:
Divide the shape into shapes you can calculate the area of: a rectangle with a semi-circle on top, minus a square.
1. Calculate the area of the rectangle. Formula for area of a rectangle is length · width
1 m · 2 m = 2 m²
2. Calculate the area of the semi-circle. Formula for a semi-circle is [tex]\frac{\pi r^{2} }{2}[/tex] (use 3.14 for π) (radius is equal to half the diameter)
3.14(0.5)² = 0.785
0.785 ÷ 2 = 0.3925 m²
3. Combine the total area
2 + 0.3925 = 2.3925
4. Calculate the area of the square that will not be painted. Formula for area of a square is s² (side · side)
0.2² = 0.04 m²
5. Subtract the area of the square from the total area
2.3925 - 0.04 = 2.3525
2.3525 rounds to 2.35 m²

Lewis Hamilton completed the first lap at the Monaco Grand-Prix with an average speed of 125 mi/h. His goal is to complete the first two laps with an average speed of 250 mi/h. How fast (in terms of average speed) should his second lap be?
Answer:
infinitely fast
Step-by-step explanation:
To have double the average speed, he must complete the two laps in the same amount of time that he spent completing the first lap. That is, he must complete the second lap in zero time.
Hamilton's average speed for the second lap should be infinite. (He needs to finish it in zero time.)

Consider the graph of the linear function h(x) = –6 + h(x) equals negative 6 plus StartFraction 2 Over 3 EndFraction x. x. Which quadrant will the graph not go through and why?
Answer:
2nd quadrant.
Step-by-step explanation:
The given function is
[tex]h(x)=-6+\dfrac{2}{3}x[/tex]
We need to find the quadrant from which the graph of function is not passing.
At x=0,
[tex]h(0)=-6+\dfrac{2}{3}(0)=-6[/tex]
So, y-intercept is (0,-6).
At h(x)=0,
[tex]0=-6+\dfrac{2}{3}x[/tex]
[tex]6=\dfrac{2}{3}x[/tex]
[tex]18=2x[/tex]
[tex]9=x[/tex]
So, x-intercept is (9,0).
It means the graph intersect negative side of y-axis and positive side of x-axis. When we join these two points, we get the graph is not passing through the 2nd quadrant.
Therefore, the required quadrant is 2nd quadrant.

Answer:
B) 122 degrees.
Step-by-step explanation:
Consider the kite :- the 2 angles at the tangents are 90 degrees so we have:
9x - 5 + 14x + 24 + 90 + 90 = 360
9x - 5 + 14x + 24 = 180
23x + 19 = 180
23x = 161
x = 7
So the obtuse angle = 14(7) + 24
= 98 + 24
= 122 degrees.
How did the temperature change if: at first it decreased by 10 % and then decreased by 30% ?
Answer:
We decreased by 37%
Step-by-step explanation:
Let x be the starting temperature
We decrease by 10 percent which means we are left with 100-10 =90 percent
.90 x
Then we decrease by 30 percent, 100 - 30 = 70
( .90x) * .70
.63x
We have .63 of the original left or 63%
100 -63 = 37
We decreased by 37%

Determine the slope of the lines parallel and perpendicular to -4x+3y=11
Answer:
parallel = 4/3
perpendicular =-3/4
Step-by-step explanation:
Solve for y
-4x+3y=11
Add 4x to each side
3y = 4x+11
Divide by 3
y = 4/3 x +11/3
This is in the form y = mx+b where m is the slope
m =4/3
The parallel line has the same slope
parallel slope is 4/3
The perpendicular line has a negative reciprocal slope
m = -(1 /4/3) = - 3/4
Answer:
[tex]\frac{4}{3}[/tex] and - [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
- 4x + 3y = 11 ( add 4x to both sides )
3y = 4x + 11 ( divide all terms by 3 )
y = [tex]\frac{4}{3}[/tex] x + [tex]\frac{11}{3}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{4}{3}[/tex]
Parallel lines have equal slopes, thus
slope of parallel line = [tex]\frac{4}{3}[/tex]
Give a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{4}{3} }[/tex] = - [tex]\frac{3}{4}[/tex]
