100 POINTS AND BRAINLIEST. PLEASE HELP!!!!!! Ava’s watering can holds 2 liters of water. She uses 200 milliliters to water each of her plants. How many plants can she water if she fills the watering can two times?
Answers
Answer:
She can water 20 plants
Step-by-step explanation:
She has a total of 2 liters in each can, and if she uses 2 full cans, she has a total of 4 liters. 4 liters=4000 milliliters.
To find the amount of plants she can water, we need to divide the amount of water she has by how much it takes to water each plant. So,
[tex]\frac{4000}{200}[/tex]
[tex]=\frac{20}{1}[/tex]
[tex]=20[/tex]
So, she can water 20 plants with two full water cans.

A triangle has an area that is 125 m2. The measure of the base is 20 m so, h = ? m.
Answers
Answer:
12.5
Step-by-step explanation:
12.5 multiplied by 20 is 250 which you divide by 2 to get the area. it plugs in to the triangle area formula which is 1/2 base times height.
Answer:
Hello! answer: h = 12.5
Step-by-step explanation:
H = 12.5 because 12.5 x 20 = 250 then we divide by 2 and get our area 125. so h = 12.5

The amount that households pay service providers for access to the Internet varies quite a bit, but the mean monthly fee is $50 and the standard deviation is $20. The distribution is not Normal: many house- holds pay a low rate as part of a bundle with phone or television service, but some pay much more for Inter- net only or for faster connections.
A sample survey asks an SRS of 50 households with Internet access how much they pay. Let x be the mean amount paid.
(a) Explain why you can't determine the probability that the amount a randomly selected household pays for access to the Internet exceeds $55.
(b) What are the mean and standard deviation of the sampling distribution of ?
(c) What is the shape of the sampling distribution of x? Justify your answer.
(d) Find the probability that the average fee paid by the sample of households exceeds $55. television service, but some pay much more for Inter- net only or for faster connections.
Answers
Answer:
(a) See Explanation
(b) [tex]\bar x =50[/tex] and [tex]\sigma_x = 0.8944[/tex]
(c) The shape is normal
(d) [tex]P(\bar x > 55) = 0[/tex]
Step-by-step explanation:
Given
[tex]\mu = \$50[/tex] -- mean
[tex]\sigma = \$20[/tex] --- standard deviation
[tex]n=500[/tex] --- sample size
Solving (a): The reason we can't determine the probability that an amount to access internet by a household will exceed $55.
The question says that a lot of households pay low rates, but the percentage of the households in this category is not given. This means that it is impossible to determine the shape of the distribution.
Hence, the probability cannot be calculated.
Solving (b): Sample mean and Sample standard deviation
The sample mean estimates the population mean
So:
[tex]\bar x =\mu[/tex]
[tex]\bar x =50[/tex]
The sample standard deviation is calculated as thus:
[tex]\sigma_x = \frac{\sigma}{\sqrt n}[/tex]
[tex]\sigma_x = \frac{20}{\sqrt{500}}[/tex]
[tex]\sigma_x = \frac{20}{22.36}[/tex]
[tex]\sigma_x = 0.8944[/tex]
Solving (c): The shape of the distribution.
We have:
[tex]n = 500[/tex] --- The sample size
According to Central limit theorem, When the sample size is greater than 30, then the shape of the distribution is normal.
Hence, the shape is normal
Solving (d): [tex]P(\bar x \ge 55)[/tex]
Calculate the test statistic (t)
[tex]t = \frac{\bar x - \mu}{\sigma}[/tex]
[tex]t = \frac{55 - 50}{0.8945}[/tex]
[tex]t = \frac{5}{0.8945}[/tex]
[tex]t = 5.590[/tex]
So:
[tex]P(\bar x > 55) = P(t > 5.590)[/tex]
Referencing the z table, we have:
[tex]P(t > 5.590) = 0[/tex]
Hence:
[tex]P(\bar x > 55) = 0[/tex]

A consumer advocate conducted a test of a popular gasoline additive that was claimed to increase gasoline mileage in cars. For
a sample of 15 cars they used the additive and determined how many more miles the car could drive when the additive was added to the gas tank.
For example, a positive 10 would mean that the car drove 10 more miles with the additive whereas a-3 would mean that the car drove 3 fewer miles with the additive.
The table shows a few data values (of how many more miles a car could drive with the additve) along with some summary statistics.

Answer:

Step-by-step explanation:
log3(x+2)-log3(x)=1
Subtraction sign means you can divide the values inside the parintheses
log3(x+2/x)=1
split up the fraction into x/x and 2/x; x/x = 1
log3(1+(2/x))=1
Change of base - three to the first power = value in parintheses
3to1st=1+(2/x)
subtract 1 from both sides
2=2/x
divide both sides by 2
x=1

Answer:
A. g(x) = √(x -5), x ≥ 5
Step-by-step explanation:
You can use the definition of an inverse function to solve for g(x).
x = f(g(x))
x = (g(x))^2 +5
x -5 = (g(x))^2 . . . . . subtract 5
√(x -5) = g(x) . . . . . take the square root
The radical contents cannot be negative, so this is only defined for x-5 ≥ 0, or x ≥ 5.
g(x) = √(x -5), x ≥ 5
