4. A punch bowl holds 80 oz of punch, that is enough for exactly 16 servings.
Hillary says that there are 20oz of punch for every 5 servings. Is Hillary correct?
Answer:
No, Hillary is incorrect. There's 20oz of punch for every 4 servings.
Step-by-step explanation:
80oz / 20oz = 4
16 servings / 4 = 4 servings
So, instead of there being 20oz of punch for every 5 servings, there would be 20oz of punch for every 4 servings.
what is 9+10 -129×5÷232²32×400÷23
Answer: 9 + 10 = 19
-129 x 5 = -645
232 exponent of 2 = 53,824
32 x 400 = 12,800
400 / 23 = 17
53,824 + 12,800 + -645 + 19 + 17 = 66015

Step-by-step explanation:
x(86.90) = 96.90
86.90x = 96.90
86.90x/86.90 = 96.90/86.90
x = 1.120

There are 135 people in a sport centre.
73 people use the gym.
59 people use the swimming pool.
31 people use the track.
19 people use the gym and the pool.
9 people use the pool and the track.
16 people use the gym and the track.
4 people use all three facilities.
Given that a randomly selected person uses at least two facilities, what is the probability they
use all the facilities?
Answer:
1/9
Step-by-step explanation:
4 people use all three facilities, then
16 - 4 = 12 people use the gym and the track and do not use the pool;
9 - 4 = 5 people use the pool and the track and do not use the gym;
19 - 4 = 15 people use the gym and the pool and do not use the track.
At least two facilities use 4 + 12 + 5 + 15 = 36 people, 4 of them use all three facilities. Thus, the probability that a randomly selected person which uses at least two facilities, uses all the facilities is 4/36 which is equivalent to 1/9

Answer: 17 degrees
Step-by-step explanation: Because you have angle A= 163, you can tell that angle B is 17 degrees (sum of angles on one side of a straight line add up to 180). Line M and line N are parallel, so they have corresponding angles, making angle B and angle X are the same. See picture attached for my diagram :). hope this helped!

Determine the five-number summary for the data set. 20, 26, 18, 31, 22, 28, 30
Answer:
min = 18Q1 = 20median = 26Q3 = 30max = 31====================================================
Explanation:
The first task is to sort the items given.
The sorted set is {18, 20, 22, 26, 28, 30, 31}
There are 7 values in that set. The median is going to be in slot 4 because n/2 = 7/2 = 3.5 rounds to 4.
The value in slot 4 is 26, meaning the median is 26.
There are 3 values below the median, and 3 values above it.
L = lower set = items below the median
L = {18,20,22}
U = upper set = items above the median
U = {28,30,31}
The median of set L is 20, showing that Q1 = 20 is the first quartile.
The median of set U is 30, meaning Q3 = 30 is the third quartile.
The min and max are exactly what they sound like: they are the smallest and largest items. In this case, we have min = 18 and max = 31.

Matthew bought 16 gallons of gas for $4.25 per gallon. How much did he spend? Show your work.
Answer:
$68.00
Step-by-step explanation:
16 x 425 = 6800
Just move the decimal 2 places to the left to get 68
Matthew spends $68 on gas as the rate of gas is $4.25 per gallon.
What is per unit?Per unit is a technique of expressing a quantity's value in terms of a base or reference quantity. Each system variable or quantity in a per-unit system is normalized in relation to its own base value.
Given Matthew bought 16 gallons of gas for $4.25 per gallon.
Since the price per gallon = 4.25
The price of the gas for 16 gallons = 4.25 * 16
The price of the gas for 16 gallons = 68.00
Therefore, Due to the $4.25 per gallon price, Matthew spends $68 on gas.

He doesn't want the margin of error to exceed 333 years. Preliminary data suggests that the standard deviation for the ages of trees in this population is \sigma=16σ=16sigma, equals, 16 years. Which of these is the smallest approximate sample size required to obtain the desired margin of error?
Using the z-distribution, as we have the standard deviation for the population, it is found that the smallest sample size required to obtain the desired margin of error is of 77.
What is a z-distribution confidence interval?The confidence interval is:
[tex]\overline{x} \pm z\frac{\sigma}{\sqrt{n}}[/tex]
In which:
[tex]\overline{x}[/tex] is the sample mean.z is the critical value.n is the sample size.[tex]\sigma[/tex] is the standard deviation for the population.The margin of error is given by:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In this problem, we have that the parameters are given as follows:
[tex]M = 3, z = 1.645, \sigma = 16[/tex].
Hence, solving for n, we find the sample size.
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]3 = 1.645\frac{16}{\sqrt{n}}[/tex]
[tex]3\sqrt{n} = 1.645 \times 16[/tex]
[tex]\sqrt{n} = \frac{1.645 \times 16}{3}[/tex]
[tex](\sqrt{n})^2 = \left(\frac{1.645 \times 16}{3}\right)^2[/tex]

Rounding up, the smallest sample size required to obtain the desired margin of error is of 77.

Let g(x) = 3(x - 6)^2 + 1. Find the range of $g$.
Answer:
[1,∞)
Step-by-step explanation:
Let's try to plug in some numbers.
When solving a problem fo range, the best place to start is where you can let the (x - b) part = 0.
This is what I mean
3(x-6)² + 1
Let x = 6
3(0)² + 1 = 1
Look how we have a 0 inside the parentheses.
That's what I mean.
Now let's try using terms smaller than 6.
Now, let's try plugging in 5
3(-1)² + 1 = 4
Now try plugging in 4
3(-2)² + 1 = 13
Looks like we will just keep going up.
Now let's try using terms bigger than 6.
Plugging in 7
3(1)² + 1 = 4
Plugging in 8
3(2)² + 1 = 13
We just go up both ways because of the x squared term.
So our smallest value is at x = 6 where we have y = 1.
If we go either direction forever to the right or left the terms to get bigger, where it approaches infinity.
So, 1 will have parentheses as it can be reached and infinity will have parentheses as it is unreachable and goes on forever.

Answer:

Step-by-step explanation:(if treasure of change is "rate of change")
Equation of a line: mx + b
m=-1/3: slope
b: y-intercept
^Whenever working with an equation of slope/rate of change the above variables have specific meanings.
Slope is another term for rate of change so the rate of change would be -1/3.
m=-1/3=slope/rate of change

Step-by-step explanation:
Multiply: (3x - 5)(-x + 4)
By applying the distributive property,
(3x - 5)(-x + 4)
