Answer:
H0: ρ= 0 against Ha : ρ≠0
Step-by-step explanation:
The null hypothesis would be the weight gains of a sample of lambs on regular feed is equal to the weight gains of the sample that receives an additional niacin supplement against the claim that the weight gains are not equal .
H0: ρ= 0 against Ha : ρ≠0
Type 1 Error would be when the H0 is true and there's no difference but H0is rejected or Ha is accepted that there is difference in the weight gains.
Type 2 Error would be when the Ha is true and there is difference but Ha is rejected or H0 is accepted that there's no difference in the weight gains.
The appropriate conclusion would be Ha is accepted and H0 is rejected fail to reject.
A confounding variable is the one which effects the results . It is the biased variable which should be identified and ignored.
For example in this experiment the independent variable would be the amount of the supplement the dependent would the weight gain but the gender of the sheep is the confounding variable. It is not directly related to amount of supplement .
1) gender of sheep
2) the breed of sheep
3) the number of sheep
4) the height of sheep
Use the distributive property to write two equivalent expressions for 6 x 53
Answer:
a. (6 * 50) + (6 * 3)
b. (6 * 40) + (6 * 13)
Step-by-step explanation:
Here, we want to use the distributive property to write equivalent expression .
We can have the given expression as follows;
6 * ( 50 + 3) = (6 * 50) + (6 * 3)
Furthermore, we can write the expression as;
6 * (40 + 13) = (6 * 40) + (6 * 13)
plz hlep ememmeememeemem me its a math ? need to do it
Answer:
Step-by-step explanation:
slope = M
M= rise / run
rise = Y2-Y1
run = X2 -X1
P1=(X1,Y1) = (3,-3)
P2=(X2,Y2) = (6,9)
M= 9-(-3) / 6-3
M=12 /3
M=4
the slope is 4
a parallel line will have the same slope
a perpendicular line will have an inverse slope or 1/4

What is an equation of the line that passes through the points (-3, -1)(and (-4, -4)? Put your answer in fully reduced form.
Answer:
y=3x+8
Step-by-step explanation:
m=3
y-(-1)=3(x-(-3))
y+1=3x+9
y=3x+8
The equation of the line passes through the point (-3, -1)(and (-4, -4) is y=3x+8.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that line passes through the points (-3, -1)(and (-4, -4)
The slope will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( -4 + 1 ) / ( -4 + 3 )
Slope = 3
The y-intercept is calculated as,
y = 3x + c
-1 = 3 x -3 + c
c = 8
The equation of the line will be,
y=3x+8

Step-by-step explanation:
According to Teo's bread recipe, he should bake the bread at ° for 30 minutes. His oven measures temperature in °F. To what temperature, in °, should he set his oven? Rewrite the formula C= 59 F-32 to find the Fahrenheit temperature that is equal to °C.
Answer:
[tex]F = \frac{9}{5}(C + 32)[/tex]
Step-by-step explanation:
Given
[tex]C = \frac{5}{9}F - 32[/tex]
First, we need to solve for F
[tex]C = \frac{5}{9}F - 32[/tex]
Add 32 to both sides
[tex]C + 32 = \frac{5}{9}F - 32 + 32[/tex]
[tex]C + 32 = \frac{5}{9}F[/tex]
Multiply both sides by [tex]\frac{9}{5}[/tex]
[tex]\frac{9}{5} * (C + 32) = \frac{5}{9}F * \frac{9}{5}[/tex]
[tex]\frac{9}{5} * (C + 32) = F[/tex]
[tex]F = \frac{9}{5} * (C + 32)[/tex]
[tex]F = \frac{9}{5}(C + 32)[/tex]
Next, is to determine the temperature in degrees Fahrenheit
However, this is not stated the degree Celsius equivalent is not stated in your question.
So, I'll assume a value for it.
Assume that C = 23
Substitute 23 for C in [tex]F = \frac{9}{5}(C + 32)[/tex]
[tex]F = \frac{9}{5}(23+ 32)[/tex]
[tex]F = \frac{9}{5}(55}[/tex]
[tex]F = 9 * 11[/tex]
[tex]F = 99[/tex]

Is 80/10 equal to -8
Answer: No
Step-by-step explanation: Two positives divided never make a negative
Answer:
No, 80/10 turned into a whole number is 8, not -8.
Step-by-step explanation:
To get a whole (1), you need to have 10/10. Since we have 10/10 8 times (80/10) this means we get a whole number of 8, not -8. Therefore, its false. 80/10 is NOT equal to -8

Answer:
x = 10
x = 27
Step-by-step explanation:
53 and 5x + 3 are vertical angles.
vertical angles are equal.
using that, you can make this equation:
53 = 5x + 3
subtract 3 from both sides of the equation
53 - 3 = 5x + 3 - 3
50 = 5x
divide both sides of the equation by 5
50/5 = 5x/5
10 = x
82 and 3x + 1 are vertical angles.
vertical angles are equal.
using that, you can make this equation:
82 = 3x + 1
subtract 1 from both sides of the equation
82 - 1 = 3x
81 = 3x
divide both sides of the equation by 3
81/3 = 3x/3
27 = x

Nick has two pieces of twine.One 20 feet long and the other one 12 feet long.If he wants cut them up to produce many pieces of twine that are all of the same length with no twine left over what is the greatest length in feet that he can make them?
Answer:
The greatest length in feet the twines can be cut into with no twine left over is 4 feet
Step-by-step explanation:
To determine the greatest length a 20 feet long twine and a 12 feet long twine can be cut into such that the pieces are of the same length and no twine is left over, we will find the highest number that can be used to divide 20 and 12 with no remainder. Hence, we will find the Highest common factor (HCF) of 20 and 12.
Factors of 20 are: 1,2,4,5,10, and 20
and the factors of 12 are: 1,2,3,4,6, and 12
The highest common factors of 20 and 12 is 4.
Hence, the greatest length in feet the twines can be cut into with no twine left over is 4 feet.

Which is the factor of 15xy-45x-6y+18?
Answer:
3 (5 x - 2) (y - 3)
Step-by-step explanation:
Factor the following:
15 x y - 6 y - 45 x + 18
Hint: | Factor out the greatest common divisor of the coefficients of 15 x y - 6 y - 45 x + 18.
Factor 3 out of 15 x y - 6 y - 45 x + 18:
3 (5 x y - 2 y - 15 x + 6)
Hint: | Factor pairs of terms in 5 x y - 2 y - 15 x + 6 by grouping.
Factor terms by grouping. 5 x y - 2 y - 15 x + 6 = (5 x y - 2 y) + (6 - 15 x) = y (5 x - 2) - 3 (5 x - 2):
3 y (5 x - 2) - 3 (5 x - 2)
Hint: | Factor common terms from y (5 x - 2) - 3 (5 x - 2).
Factor 5 x - 2 from y (5 x - 2) - 3 (5 x - 2):
Answer: 3 (5 x - 2) (y - 3)
Clarissa wants to see Luke Bryan in concert. Tickets cost $54.50 each. She has already saved $25 and is going to save $5 per week from her allowance. The inequality 25 + 5w ≥ 54.50 can be used to determine the number of weeks, w, Clarissa will need to save in order to be able to have at least enough money buy a ticket to the concert. Which statement about the number of weeks that Clarissa has saved is true?
Answer:
The minimum number of weeks Clarissa needs to save is 6 weeks.
Step-by-step explanation:
Clarisaa wants to go to the concert with the luke bryan
Ticket cost=$54.50
Inequality= 25+5w[tex]\geq[/tex] 54.50
upon solving the inequality we get
5w [tex]\geq[/tex] 54.50-25
5w [tex]\geq[/tex] 29.5
w [tex]\geq[/tex] 5.9 = 6weeks approximately
so The minimum number of weeks clarissa needs to save is 6 weeks

A scale drawing of an office space uses a scale of 2 in. : 3 yd. The scale drawing has an area of 12 square inches. What is the area of the actual office space?
Answer: The area of the actual office space = 18 sq. yards
Step-by-step explanation:
Formula : Image length = Scale factor x original length
Given: A scale drawing of an office space uses a scale of 2 in. : 3 yd.
i.e. scale factor = [tex]\dfrac23[/tex]
The scale drawing has an area of 12 square inches.
i.e. [tex]\text{12 sq. inches}=\dfrac23\times\text{area of the actual office space }[/tex]
[tex]\Rightarrow\ \text{Area of actual office space}=\dfrac{3}{2}\times12=18\text{ sq. yards}[/tex]
Hence, the area of the actual office space = 18 sq. yards
