The null and alternative hypotheses are [tex]H_o[/tex] μ= 64.2 and [tex]H_a[/tex]: μ ≠ 64.2 respectively.
What is the hypothesis?In statistics, hypothesis testing is the process by which an analyst tests an assumption about a population's parameter. Using sample data, hypothesis testing is performed to examine the plausibility of a theory.
The average height of an 18-year-old American woman is 64.2 inches
Hypotheses state claims about a population parameter.
p: population proportion: population mean
σ: population standard deviation
The null hypothesis asserts that the sample size equals the claim value:
[tex]H_o[/tex] :μ= 64.2
The alternate hypothesis expresses the inverse of the null hypothesis (As per the claim):
[tex]H_a[/tex] : μ ≠ 64.2
μ = The average height of 18-year-old American women in the population.
[tex]H_o[/tex] :μ= 64.2
[tex]H_a[/tex] : μ ≠ 64.2
Thus, the null and alternative hypotheses are [tex]H_o[/tex] μ= 64.2 and [tex]H_a[/tex]: μ ≠ 64.2 respectively.

solve system of equations algebraically
Answers
Answer:
y=-2 x=-2
Step-by-step explanation:
y=-x-4
y=x
you can plug y in for x in the first equation by using substitution
y=-y-4
and then you solve for y
2y=-4
y=-2
so y equals -2. Since y=x, x also equals -2. Therefore
y=-2 x=-2

Katherine uses $\frac{7}{10}$ of a gallon of red paint to paint $\frac{3}{5}$ of her wall. How many gallons of red paint will she use to paint her whole wall? There is no 5/5
Answers
Answer:
1.167 gallons
Step-by-step explanation:
Given that:
Fraction of red paint used = 7/10 of a gallon
Fraction of wall painted = 3/5
Gallon of paint required to paint the entire wall:
Fraction of entire wall = 1/1
7/10 paint = 3/5 wall
x paint = 1 wall
Cross multiply
(3/5)x = 7/10
Divide both sides by 3/5
3/5x ÷ 3/5 = 7/10 ÷ 3/5
(3/5)x * 5/3 = 7/10 * 5/3
x = 35 / 30
x = 7/6 = 1.167 gallons of red paint

The angles of a triangle add to 180, add the angles and solve for x
Answer:
x = 14
Step-by-step explanation:
3x + 9 + 5x - 1 + 4x + 4 = 180 because triangles have 180 degrees
12x + 12 = 180
180 - 12 = 168
12x = 168
168/12 = 14
x = 14
The angle measures of a triangle are 2y + 3 degrees, 9y – 7 degrees, and 7y + 4 degrees. Which of the following is not one of the angle measures of the triangle?
Answers
Answer:
55
Step-by-step explanation:
The measures of the angles are 23, 83, and 74 degrees. 97 degrees is not the measure one of the angle measures of the triangle option (B) is correct.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called a "Angle."
It is given that:
The angle measures of a triangle are 2y + 3 degrees, 9y – 7 degrees, and 7y + 4 degrees.
As we know,
The sum of the interior angle of the triangle is 180 degrees
2y + 3 + 9y - 7 + 7y + 4 = 180
18y = 180
y = 10
2y + 3 = 2(10) + 3 = 23 degres
9y - 7 = 9(10) - 7 = 83 degrees
7y + 4 = 7(10) + 4 = 74 degrees
Thus, the measures of the angles are 23, 83, and 74 degrees. 97 degrees is not the measure one of the angle measures of the triangle option (B) is correct.

Jason has a lemonade stand but he already made $26 he charges his customers one dollar per lemonade Kaylee has a lemonade stand where she made $16 and she charges the customers two dollars per lemonade which equation shows the number of lemonade, eggs, Kaylee needs to sell to make a higher profit than Jason. A. 26-x<16-2x. B. X+26<2x+16 C. 26+2x>16+x D. 16x+2>26x+1
Answers
Answer: B. X+26<2x+16
Step-by-step explanation:
Let x be the number of lemonade Kaylee needs to sell to make a higher profit than Jason.
Given: Jason has made $26. he charge $1 per lemonade.
Total earnings after x lemonades = $26+($1) x
= $(26+x)
Kaylee has made $16. he charge $2 per lemonade.
Total earnings after x lemonades = $16+($2) x
= $(16+2x)
Required inequality : (16+2x)> (26+x)
