Answer: 150
Step-by-step explanation:
30% = 0.3
100-30=70
70% = 0.7
0.7 X 500 = 350
500-350 = 150
For every 500 Americans, the number of people fall asleep before the New Year is, 150
What is the percentage?The percentage is a mathematical term, which means a number or a ratio which is represented in fractions of 100. We use the '%' symbol to represent the percentage.
Formula for percentage;
Percentage = (present quantity/whole quantity)×100
Given that,
30% of Americans will fall asleep before midnight
For every 500 Americans, about how many will be sleeping before the New Year?
Percentage = num. of people fall asleep in sample/Total people in sample ×100
30 = N/500×100
N = 150
Hence, the number of people fall asleep is 150

Suppose that out of 10 trees planted in a yard, only five survived. What kind of hypothesis could you make about this observation or event
Answer: The condition to which the trees were exposed played a part in their inability to survive.
Step-by-step explanation:
From the report given in the question, we can hypothesize on a number of grounds as to why only 5 of the 10 trees survived. Hypothesis is very common in statistical parlance as it could be referred to as a claim about a particular event which is only inferred and has not been proved either wrong or right. This hypothesis or claim are further scrutinized or tested in other to establish a fact or validity of the claim. Hence, we could infer that the reason why only 5 of the trees planted survived is due to harsh weather condition. However, this claim will be subjected to further test before establishing the truth or significance of the hypothesis.

Answer: Angle 1 = 150 - corresponding angles
Angle 2 = 150 - alternate exterior angles
Step-by-step explanation:
To find the measure of angles ∠1 and ∠2, we are using vertical angle theorem and corresponding angles concept.
From the given figure measure of one of the angle is 150°.
What are angles of parallel lines?Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.
Corresponding angles are angles that occur on the same side of the transversal line and are equal in size. They are either both obtuse or both acute.
Here, ∠1 = 150° (Corresponding angles)
∠1 =∠2 = 150° (Vertically opposite angles are congruent)
To find the measure of angles ∠1 and ∠2, we are using vertical angle theorem and corresponding angles concept.

Evaluate the function g(x) = -2x2 + 3x - 5 for the input values -2, 0, and 3.
9(-2) = -2(-2)2 + 3(-2) – 5
9(-2) = -2(4) - 6 - 5
g(-2) =-19
g(0) =-5
g(3) =-14
Answer:
g(-2) = -19, g(0) = -5 and g(3) = -14
Step-by-step explanation:
The given function is :
[tex]g(x) = -2x^2 + 3x - 5[/tex] ...(1)
We need to find the function when x = -2,0 and 3.
Put x = -2 in equation (1).
[tex]g(-2) = -2(-2)^2 + 3(-2) - 5\\\\=-19[/tex]
Put x = 0 in equation (1).
[tex]g(0) = -2(0)^2 + 3(0) - 5\\\\=-5[/tex]
Put x = 3 in equation (1).
[tex]g(3) = -2(3)^2 + 3(3) - 5\\\\=-14[/tex]
Hence, g(-2) = -19, g(0) = -5 and g(3) = -14

how dose north america achieve 480VAC with 3 pole 120VAC
Answer:
There are a variety of factors driving the
adoption of 415/240VAC distribution. First,
distributing at these increased voltages
enables overall efficiency to be enhanced
by eliminating the need for a voltage
transformation along the power path. For
example, in a 415V system, the L-N voltage
is 240V, which is compatible with most all IT
loads. By shifting the UPS output distribution
voltage to 415/240 V three-phase (L-L/
L-N), most of the existing servers today can
be powered with 240V single-phase (L-N)
without any intermediate transformation.
Removing the need for a transformer
streamlines the power path and can increase
efficiency approximately 1.5 percent.
The adoption of a 415/240VAC distribution
model also can yield additional savings at
the device-level in the form of increased
efficiency for server power supplies. As
previously mentioned, today’s power
supplies can handle a wide range of incoming
voltages. Based on the actual voltage being
fed into the power supply, efficiencies can
range from as low as 80 percent (at 100V
nominal) to as much as 94 percent (at 240V
nominal) across all manufacturers.
Furthermore, while the typical efficiency
differential between 240V and 208V gained
at the server power supply today is a relatively
minimal, only 0.3 percent across most of
the load range, the efficiency differential
between 240V and 120V servers can be as
much as 2 percent for a given power supply.
It is this value that often gets overstated by
some manufacturers when comparing 415V
distribution to “traditional methods,” as
there are relatively few servers or peripherals
installed today that are operating at 120V.

A recent report indicated that 22 percent of the households in a certain community speak a
language other than English at home. A reporter will randomly select a household from the
community until the first houehold that speaks a language other than English at home is
selected. Let random variable Q represent the number of attempts needed until the first
household that speaks a language other than English at home is selected. The random variable
Q has a geometric distribution with p = 0.22. Which of the following is closest to the variance
of the random variable?
Answer:
16.1157
Step-by-step explanation:
The random variable Q has a geometric distribution with p = 0.22. The variance of the random variable will be 16.1157.
What is the variance of the random variable?A spread measure for a random variable distribution quantifies how much the values of a random variable deviate from the value that is predicted.
For a discrete random variable, the variance is determined by adding the square of the difference between the value of the random variable and the anticipated value, together with the chance that the value of the random variable will occur, across all of the values of the random variable.
It is given that 22 percent of people in the community speak a language other than English at home.
The required number of tries should be represented by the random variable Q.
The geometric distribution of the random variable Q has a p-value of 0.22.
The variance of a random variable is
V(Q) = (1-p)/p²
V(Q) = (1-0.22)/(0.22)²
V(Q) =0.78/0.484
V(Q) =16.1157
Thus, the random variable Q has a geometric distribution with p = 0.22. The variance of the random variable will be 16.1157.

The stock market dropped 220 points on Monday. It lost another 48 points on Tuesday, and on Wednesday, it gained 96 points. What was the amount of change over those three days.
Request you to finish this please
48 points gained in those 3 days.
Subtract 220 with 48, then add 96. Last step would be subtracting 220 with the amount they have now in those 3 days to find how much points the stock market gained in those 3 days.
Subtract 220-48.It‘ll be 172.
Add 172 with 96. 172+96=268.
Subtract 268 with how much points the stock market had 3 days ago. 268-220.
Sot eh stock market gained 48 points in 3 days.
