Answer:
The sample does not provide sufficient evidence that women today are taller than women in 1990.
The difference in mean height is not significant to arrive at such a conclusion.
Step-by-step explanation:
Mean height of women 20 year of age or older in 1990 = 63.7 inches
Mean height of women 20 years of age or older in 2015 = 63.9 inches
The standard deviation of the mean height in 2015 = 0.5 inch
The difference between the two years' mean height is 0.2 (63.9 - 63.7) inch.
This difference is less than the standard deviation of the mean height in 2015.
Therefore, the difference does not provide sufficient evidence that women today are taller than women in 1990.

A popular game requires the player to select the same five numbers out of a set of allowed numbers that will be drawn at random by the lottery commission. For the next game, if you select the five numbers that won in the most recent prior drawing, your chances of winning will:
Options:
A.) decrease because the same five numbers are not likely to occur again so soon.
B.) Increase because those five numbers must be lucky.
C.) be unaffected because every set of five numbers is equally likely on every attempt.
D.) be unknown because it depends on how many times those five numbers have won in the last several drawings.
Answer:
be unaffected because every set of five numbers is equally likely on every attempt.
Step-by-step explanation:
Number selection in the lottery is randomized with each set of number having equal chances of being selected. This means that each and every selection attempt is independent and the outcome of each attempt does not depend on any prior outcome or event. This means that if the numbers drawn from the most previous prior drawing are selected on the next attempt, the probability of winning on the next attempt Neither increases nor decreases. Hence , the probability of winning on the next attempt with this selection is unaffected.
3. The rectangle below has an area of 297 in. Find the length of the diagonal.
14
27 in.
odhad.
9514 1404 393
Answer:
29.15 in
Step-by-step explanation:
The area of a rectangle is given by the formula ...
A = LW
Filling in the given information, we can find the missing side length.
297 in² = (27 in)h
h = (297 in²)/(27 in) = 11 in
The length of the diagonal can be found from the Pythagorean theorem.
d² = 27² + 11² = 729 +121 = 850
d = √850 = 5√34 ≈ 29.15476
The length of the diagonal is about 29.15 inches.

Find the area of this triangle.
Round to the nearest tenth.
7 in
133
13 in
[ ? ) in2
Answer:
33.3 in²
Step-by-step explanation:
Apply the formula for finding the area of triangle that has an included angle and two given sides, which is, Area = ½*a*b*Sin*C
Where,
a = 7 in
b = 13 in
C = 133°
Plug in the values
Area = ½*7*13*Sin(133)
Area = 33.2765935 ≈ 33.3 in² (nearest tenth)

Answer:
m∠X = 110°
m∠V = 60°
Step-by-step explanation:
1.) Angle Y and W are equal from the markers, which means the angles are equal
35*2 = 70
180 - 70 = 110 ( You know it has to be greater than 90 because it's larger than a corner angle)
2.) This is another isosceles (equal angle and sides)
Some times all sides aren't equal on isosceles but you can see these are

a stone is thrown downward with an intitial velocity of 29.5 m/sec will travel a distance of a meters, where s(t) = 4.9t^2 + 29.4 and t is in seconds. if a stone is thrown downward at 29.4m/sec from a height of 132.3 m, how long will it take the stone to hit the ground?
Answer:
t = 9 s
Step-by-step explanation:
A stone is thrown downward with an intitial velocity of 29.5 m/sec will travel a distance of a meters, where
[tex]s(t) = -4.9t^2 + 29.4+132.3[/tex]
We need to find when the stone will hit the ground. It means when s(t) = 0. So,
[tex]-4.9t^2 + 29.4t+132.3=0\\\\t=-3\ and\ t=9[/tex]
So, the stone will take 9 seconds to hit the ground. Hence, this is the required solution.

Step-by-step explanation:
Please help ASP!!!! A= positive, B=Negative, C=Zero
Answer:
B. Negative
Step-by-step explanation:
So first, we want to locate the variable.
y (x/y) = (y/1) (x/y)
= (xy/y)
= x
The y/y cancels out and now we know we need to find the sign of x. Because x is to the left of 0, it's negative. Anything to the left decreases and anything to the left of 0 is (-).

The simplified expression is y.
To solve the expression [tex](x^2 y^5 / x^3 y^8) \times (x^5 y^6 / x^4 y^2)[/tex], we can simplify and perform the necessary operation
Let's break it down step by step:
Step 1: Simplify the expression inside the parentheses.
[tex](x^2 y^5 / x^3 y^8) \times (x^5 y^6 / x^4 y^2)[/tex]can be simplified as follows:
= [tex](x^{(2-3)} y^{(5-8)}) \times (x^{(5-4) }y^{(6-2)})[/tex]
= [tex](x^{(-1)} y^{(-3)}) \times (x^1 y^4)[/tex]
= [tex](1/x y^{(-3)}) \times (x y^4)[/tex]
=[tex]x^0 \times y^{(-3+4)[/tex]
= [tex]1 \times y^1[/tex]
= y
Therefore, the simplified expression is y.
The explanation is as follows:
We can simplify the given expression by applying the laws of exponents. In this case, when dividing two terms with the same base (x or y), we subtract their exponents. Additionally, any term raised to the power of 0 is equal to 1.
After simplifying the expression, we find that the answer is y. This means that the original expression[tex](x^2 y^5 / x^3 y^8) \times (x^5 y^6 / x^4 y^2)[/tex]simplifies to just y.
