Jodi's car used 12 gallons of gas to travel
456 miles. How many miles did her car travel per
gallon of gas?
It cost Jodi $44.88 to buy 12 gallons of gas. What
was the cost per gallon of gas?
Answer:
38 miles per Gallon of Gas and she paid $3.74 per gallon of Gas
Step-by-step explanation:
Answer 1 is =
miles ÷ gallons
= 456÷ 12
= 38 Miles
Answer 2 is =
total money spent ÷ number of gallons
= $44.88 ÷ 12
= $3.74

416 ÷ 652
Show your work and I'll give brianliest
Answer: 0.63803681
Step-by-step explanation:
652/416 simplified= 163/10
then just divide bc its easier.
hope it helped :))
Answer:
0.63803680981
Step-by-step explanation:
First, you can see there is no way to divide 652 into 416. So, you need to add a decimal to 416. Then, you would multiply 652 by 6 and get 3912. You subtract 3912 by 4160 and get 248. Then, you add a 0 to that number. And then, you would keep repeating the steps. Decimal, multiply, subtract.

g According to the 2010 census, 30% of American adults were worried about global warming. A Gallup poll (assumed to be a random sample) was conducted between March 6 and March 9, 2014 on a random sample of 1048 adults. (a) Describe the sampling distribution of the sample proportion of American adults worried about global warming for a random sample of 1048 American adults. (b) (3 points) Compute the probability that the sample proportion from a random sample of 1048 adults who are worried about global warming is above 35%. (c) (2 points) Based on your answers above, do you think it would be unusual to get 40% of 1048 randomly selected American adults being worried about global warming
Answer:
a) By the Central Limit, the sampling distribution of the sample proportion of American adults worried about global warming is approximately normal with mean 0.3 and standard deviation 0.0142.
b) 0.0002 = 0.02% probability that the sample proportion from a random sample of 1048 adults who are worried about global warming is above 35%.
c) Yes, as 35% already has a z-score above 2, which means that any value above 35%, including 40%, would be unusual.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
If the z-score is lower than -2 or greater than 2, the measure X is considered unusual.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
30% of American adults were worried about global warming.
This means that [tex]p = 0.3[/tex]
(a) Describe the sampling distribution of the sample proportion of American adults worried about global warming for a random sample of 1048 American adults.
Sample of 1048 means that [tex]n = 1048[/tex]
The mean is [tex]\mu = p = 0.3[/tex]
The standard deviation is [tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.3*0.7}{1048}} = 0.0142[/tex]
By the Central Limit, the sampling distribution of the sample proportion of American adults worried about global warming is approximately normal with mean 0.3 and standard deviation 0.0142.
(b) (3 points) Compute the probability that the sample proportion from a random sample of 1048 adults who are worried about global warming is above 35%.
This is 1 subtracted by the pvalue of Z when X = 0.35. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.35 - 0.3}{0.0142}[/tex]
[tex]Z = 3.53[/tex]
[tex]Z = 3.53[/tex] has a pvalue of 0.9998
1 - 0.9998 = 0.0002
0.0002 = 0.02% probability that the sample proportion from a random sample of 1048 adults who are worried about global warming is above 35%.
(c) (2 points) Based on your answers above, do you think it would be unusual to get 40% of 1048 randomly selected American adults being worried about global warming
Yes, as 35% already has a z-score above 2, which means that any value above 35%, including 40%, would be unusual.

Answer:
31 square inches
Step-by-step explanation:
You can divide the shape into pieces several ways. The total area will be the sum of the areas of the pieces.
If we draw a horizontal line across the figure 2 inches up from the bottom, the figure is divided into a triangle and two rectangles.
The triangle has a base of 8 -3-2 = 3 inches, and a height of 4 -2 = 2 inches. Its area is ...
A = (1/2)(3 in)(2 in) = 3 in²
The rectangle below the line has a base of 8 inches and a height of 2 inches. Its area is ...
A = bh = (8 in)(2 in) = 16 in²
The rectangle above the line has a base of 3 inches and a height of 4 inches. Its area is ...
A = bh = (3 in)(4 in) = 12 in²
Then the total area of the figure is ...
(3 + 16 + 12) in² = 31 in² . . . . the area of the figure

Help me with this question please!,! (3/3)
Answer:
The first one = add three matches to the right side(on horizontal, two that or on top and bottom vertically.)
Second: Start with 5, and keep adding 3 until 26. 5 + 3+3+3+3+3+3+3
Or (26-5)/3 = 21/3 = 7
7 additions are needed so 7+1 = 8

Step-by-step explanation:
2x - 5)18x⁴- 45x³ - 10x² + 39x - 35(9x³- 5x²+ 7
18x⁴- 45x³
-10x² + 39x

The budget for salaries for three employees at the Sunshine Food Truck is $1500. If the assistant manager makes twice as much as the cook and the server makes $100 less than the cook, how much do each of the employees make for the month?
Answer:
Assistant manager sal= $800
cook sal = $400
server sal = 300
Step-by-step explanation:
lets say 3 people salaries are x, y and z respectively
let x be the cook salary
cook salary = x
assistant manager sal = y = 2x
server sal = z = x - 100
putting in the equation total salary three together make = 1500
x+y+z = 1500
x+2x+(x-100) = 1500
4x -100 = 1500
4x = 1600
x = 400
y = 2x = 2x400 = 800
z = x - 100 = 400 - 100 = 300

Muriel says she has written a system of two linear
equations that has an infinite number of solutions. One
of the equations of the system is 3y = 2x - 9. Which
could be the other equation?
Answer:
The other equation could be: 6y = 4x - 18
Step-by-step explanation:
System with infinite number of solutions:
A linear system has an infinite number of solutions when one equation is a multiple of another.
One of the equations of the system is 3y = 2x - 9. Which could be the other equation?
A multiple of 3y = 2x - 9
Multiplying by 2, the other equation could be: 6y = 4x - 18

Answer:
Exact form: 5/2
Decimal form: 2.5
Mixed number form: 2 and 1/2
Step-by-step explanation:
when you divide a fraction you keep, change, flip
Equation: 5/8 ÷ 1/4
keep 5/8 the same
change the divide symbol into a multipulcation symbol
flip 1/4 the other way, so it's 4/1 (it's a whole number now)
then just multiply across
Equation now: 5/8 × 4/1
