-gallon jug of milk every 3 days. At what rate do they drink milk?
Simplify your answer and write it as a proper fraction, mixed number, or whole number
Answer:
4 gallons/1 day
Step-by-step explanation:
What is a rate? A rate is writing a ratio in fraction form. A ratio is the proportion of two things. (ex: for every 1 dog, there are two cats.)
Creating the ratio: For the ratio, there is no given amount of which one needs to come first, but because it is about the milk, I put that first. In the problem it says 12 gallons for 3 days so: 12/3
Simplifying: To simplify, think of the largest factor between the two numbers. If you can't immediately, think of one factor in common and keep simplifying. In this case, 4 is the greatest common factor between these. To simplify, divide both sides by four, and that is your answer: 4: 1

You need the sample mean, sample proportion , and the standard error which depend on z or t, sigma or s, and n
A baseball is thrown in the air from center field to home plate. The path of the baseball is represented by the equation p(x)=−7x2+52x+99. How long will it take for the ball to get to home plate?
Tell me what steps went wrong as I solved this problem. Explain how to fix it.
Problem:
P(x) = -7x2 +52x+99
Step 1: -7x2 +52x+99 = 0
Step 2: a = -7 b = 52 c = 99
Step 3: −52±(52)2−4(−7)(99)√2(−7)
Step 4: −52±5476√14
Step 5:−52±7414
Step 6: x = 117 x = - 9
Answer: 117 seconds
Answer:
steps 3 went wrong
Step-by-step explanation:
the quadratic is
(-b +/- √ ( b^2 - 4ac) )/2a
-52 + √( 2704 +2772) /-14
-52 +74) / -14 = -22/14 = -11/7
-52 -74 / -14 = -126/-14 = 9
How are theoretical probability and experimental probability related
Answer:
Experimental probability is the result of an experiment. Theoretical probability is what is expected to happen. Three students tossed a coin 50 times individually.
Step-by-step explanation:
Experimental probability is found through experiments while theoretical probability are not.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
Theoretical probability is the probability that we use normally which describes the percent or probability that an event is likely to happen. This is found using logic.
Experimental probability is the probability that we calculate through the actual experiments that describes the frequency of an event happening. This is found using experiments which are repeated.
They can be same, both of which describes the probability of happening an event.
Hence the experimental probability is found through experiments while theoretical probability are not.

XYZ is transformed on a coordinate plane to obtain its congruent image X'Y'Z. Which of the following statements could be true?
Answer:
The answer is D: only I and II
Step-by-step explanation:
I know for sure this is the correct answer. Hope this helped! Mark me Brainliest!
The true statements are X'Y'Z' becomes the translated image of the triangle XYZ. X'Y'Z' becomes the reflected image of the triangle XYZ.
What is the congruent triangle?Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
When XYZ is transformed on a coordinate plane to obtain its congruent image X'Y'Z.
X'Y'Z' becomes the translated image of the triangle XYZ.
X'Y'Z' becomes the reflected image of the triangle XYZ.
X'Y'Z' doesn't become the rotated image of the triangle XYZ.
Thus, Option I and II are true statements. so D is the correct answer.

There are only seven days left until we launch of our new product and we only have $668 left in our promotion budget we need to spend $85 on the last day can you please calculate how many dollars a day we can spin on the remaining days
Answer:
$97.17
Step-by-step explanation:
First, subtract 85 from 668:
668 - 85
= 583
This means that our budget for all of the days excluding the last day is $583
To find how much can be spent on the remaining days, divide 583 by 6:
583/6
= 97.17
So, approximately $97.17 can be spent on the remaining days

Answer:
x² + 4x
Step-by-step explanation:
Area of the rectangle = length × width
length = x + 4
width = x
Therefore,
Area = x(x + 4)
Area = x*x + x*4
x² + 4x

Weight Loss Program Suppose that a weight loss company advertises that people using its program lose an average of 8 pounds the first month, and that the Federal Trade Commission (the main government agency responsible for truth in advertising) is gathering evidence to see if this advertising claim is accurate. If the FTC finds evidence that the average is less than 8 pounds, the agency will file a lawsuit against the company for false advertising. What are the null and alternative hypotheses the FTC should use
Answer:
The null hypothesis is [tex]H_{0}: \mu = 8[/tex], and the alternative hypothesis is [tex]H_{a}: \mu < 8[/tex]
Step-by-step explanation:
At the null hypothesis, we test if the mean is equal to a certain value.
At the alternate hypothesis, we test if the mean is less than, more than, or different of the value tested at the null hypothesis.
Claims to lose an average of 8 pounds the first month
This means that the null hypothesis is [tex]H_{0}: \mu = 8[/tex]
If the FTC finds evidence that the average is less than 8 pounds, the agency will file a lawsuit against the company for false advertising.
FTC tests if the mean is less than 8, so the alternate hypothesis is [tex]H_{a}: \mu < 8[/tex]

Answer:
a) radius: 6 (m); mass: 22 (kg)
b) volume: 19 (m³)
c) d ≈ 2.8×10^3 kg/m³
Step-by-step explanation:
The order of magnitude is the exponent of 10 when the number is written in scientific notation.
a) radius: 1.6×10^6 m, so the order of magnitude is 6 when the units are meters.
mass: 4.8×10^22 kg, so the order of magnitude is 22 when the units are kg.
__
b) The volume is ...
V = (4/3)πr^3 ≈ 1.716×10^19 m^3, so the order of magnitude of the volume is 19 when the units are m^3.
__
c) The ratio of mass to volume is ...
d = (4.8×10^22)/(1.716×10^19) ≈ 2.8×10^(22-19) = 2.8×10^3 kg/m^3, so the order of magnitude is 3 when the units are kg/m^3.
