Answer:
S=H+2
Step-by-step explanation:
OK, so hailey is the variable H. And she is 2 years younger than her sister.
What is the age of her sister?
So we know it has to be, hailey's age + something? = age of her sister.
what is that +something? it's the number "2 years younger" so hailey's age; which is h, plus 2 is equal to her sister's age.
H+2=S
OK, why do we need to add 2? instead of minus two? Because hailey is 2 years younger than her sister, so you want hailey's age. If you were to minus 2, you'd be thinking that hailey is OLDER than her sister. Because if you want to her sister's age, you would have to SUBTRACT 2 because you are OLDER than her. So if you are younger than the sister, you would add to get your sister's age.
Answer:
S=H+2

Answer:
The answer is x= 50 and y=50.
Step-by-step explanation:
So a straight line is always equal to 180 degrees. So, to find the length of the inner angle, subtract 100 from 180= 80. Now that you've gotten the value of that angle, you'll have to find x and y. All angles of a triangle add up to 180 degrees. 180-80= 100. The small dash on both of those lines means they are equal. Do 100/2 = 50. Hope this helps!

In a 2^4 factorial design, the number of degrees of freedom for the model, assuming the complete factorial model, is:_____
a. 7
b. 5
c. 6
d. 11
e. 12
f. none of the above.
Answer:
None of the above
Step-by-step explanation:
Given
[tex]Design = 2^4[/tex]
Required
Determine the degree of freedom (df)
df is calculated as follows;
[tex]df = N- 1[/tex]
In this case:
N = Number of designs,
[tex]N = 2^4[/tex]
[tex]N = 16[/tex]
Substitute 16 for N in [tex]df = N- 1[/tex]
[tex]df = 16 -1[/tex]
[tex]df = 15[/tex]
Hence, none of the options answer te question

Step-by-step explanation:
A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 420.0 gram setting. It is believed that the machine is underfilling the bags. A 33 bag sample had a mean of 417.0 grams. A level of significance of 0.01 will be used. Determine the decision rule. Assume the variance is known to be 576.00.
Answer
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to conclude that the machine is underfilling the bags
Step-by-step-explanation:
From the question we are told that
The population mean is [tex]\mu = 420.0 \ g[/tex]
The sample size is n = 33 bags
The sample mean is [tex]\= x = 417.0 \ g[/tex]
The level of significance is [tex]\alpha = 0.01[/tex]
The variance is [tex]\sigma^2 = 576.0[/tex]
The null hypothesis is [tex]H_o : \mu = 420[/tex]
The alternative hypothesis is [tex]H_a : \mu < 420[/tex]
Generally the standard deviation is mathematically represented as
[tex]\sigma = \sqrt{\sigma^2}[/tex]
=> [tex]\sigma = \sqrt{576 }[/tex]
=> [tex]\sigma = 24[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{ \= x - \sigma }{ \frac{\sigma}{\sqrt{n} } }[/tex]
=> [tex]z = \frac{417 - 420 }{ \frac{24}{ \sqrt{ 33} } }[/tex]
=> [tex]z = -0.71807[/tex]
From the z table the area under the normal curve to the left corresponding to -0.71807 is
[tex]p-value = P(Z < -0.71807 ) = 0.23636[/tex]
Generally looking at the values we see that
[tex]p-value > \alpha[/tex] , hence
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to conclude that the machine is underfilling the bags

ON A COMPUTER SCREEN ANSWER ASAP
Point M is drawn as the midpoint of BC.
Which of the following could be used as part of the proof that B2C? Select three that apply.
AB AC because of the definition of an isosceles triangle
BAC because corresponding parts of congruent triangles are congruent.
AABM 4 AACM because of the SAS triangle congruence criterion
BMCM because of the definition of a midpoint
AM A AM because of the Symmetric Property
Answer:
A. AB = AC because of the definition of an isosceles triangle
B. ∠B = ∠C because corresponding parts of congruent triangles are congruent.
D. BM = CM because of the definition of a midpoint
Step-by-step explanation:
A. An isosceles triangle is a triangle with two equal sides, hence:
AB = AC because of the definition of an isosceles triangle. option A is correct.
D. Since Point M is drawn as the midpoint of BC, hence:
BM = CM because of the definition of a midpoint. Option D is correct.
E. Reflexive property of congruence states that an angle, line segment, or shape is always congruent to itself. hence AM ≈ AM because of reflexive property.
AM ≈ AM because of the Symmetric Property is wrong. Option E is wrong.
C) The side - side - side (SSS) triangle congruence theorem states that if all the sides of two triangles are equal, then they are congruent triangles.
Since BM = CM, AM = AM and AB = AC, hence ΔABM = ΔACM because of the SSS triangle congruence criterion
ΔABM = ΔACM because of the SAS triangle congruence criterion is wrong. Option C is wrong.
D. Corresponding parts of congruent triangles are congruent. hence:
∠B = ∠C because corresponding parts of congruent triangles are congruent. Option B is correct

Step-by-step explanation:
A 42-inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece is 3 times as long as the first piece. If x represents the length of the first piece, find the lengths of all three pieces.
Answer:
The first piece has a length of 7 inches, the second has a length of 14 inches and the third has a length of 21 inches.
Step-by-step explanation:
x represents the length of the first piece.
Hence, the second piece has a length of 2x and the third piece has a length of 3x.
Hence, x + 2x + 3x = 42 inches.
x + 2x + 3x = 42 inches
6x = 42 inches
x = 7 inches
Hence, the first piece has a length of 7 inches, the second has a length of 14 inches and the third has a length of 21 inches.

Solve the rational equation x over 4 equals x squared over quantity 3 times x plus 3 and check for extraneous solutions.
x = 1; x = 0 is an extraneous solution
x = 0; x = −1 is an extraneous solution
x = 0 and x = 1
x = 0 and x = −1
Answer:
x is -9 is an extraneous solution
Step-by-step explanation:
Given the expression
x/4 = x²/3(x+3)
We are to find the value of x
Cross multiply
3x(x+3) = 4x²
3x²+9x = 4x²
3x²-4x² = 9x
-x² = 9x
-x = 9
x = -9
Hence the value of x is -9 is an extraneous solution
Emma wants to build a fence around the perimeter of her lawn. Each foot of fence costs $2. The rectangular lawn has an area of 364 square feet and a width of 14 feet. How much will the entire fence cost?
Answer:
[tex]\$160[/tex]
Step-by-step explanation:
To find the cost of the entire fence, we need to first determine the lawn's length before calculating its perimeter.
Area of rectangular lawn = [tex]lw[/tex] (formula for the area of a rectangle)
[tex]364=14l[/tex]
[tex]l=26[/tex] feet
Now that we have the lawn's length and width, we can calculate the perimeter:
Perimeter [tex]= 2l+2w[/tex] (formula for the perimeter of a rectangle)
[tex]=2(26)+2(14)[/tex]
[tex]=80[/tex] feet
Since each foot of lawn costs $2, then the cost of the entire fence will be:
[tex]80\times2 = \$160[/tex]
∴ The entire fence costs [tex]\$160[/tex].
