Answer:4.8
Step-by-step explanation:
if 6 is added to a quarter of a certain number the answer is 18.
what is the number?
Answer:
48
Step-by-step explanation:
6+x/4 = 18
x/4 = 12
x= 48
Answer:
x = 48
here's your solution
=>. let the number be. X
=> now , quater of this number = X/4
=> then 6 is added to it
=> we get this. =. 6 + X/4
=> it is given that this number is equal to 18
=>. so, our final equation is 6 + X/4 = 18
=> solve , X/4 = 18 - 6
=> X/4 = 12
=>. X = 12*4
=> X = 48

Yang is a car salesperson at Honda dealership. He earns monthly salary of $2,400 and an $250 bonus for each vehicle he sells to a customer. 1. Create an equation to represent the total earnings, t, Yang can make selling v, vehicles in one month.
2. How many vehicles does Yang need to sell in a month to earn a total of $5150?
3. How many vehicles does the salesperson need to sell in a month to earn at least $6000? Write an inequality and solve algebraically using inverse operations.
Answer:
1. 2400+250v=t
2. 11
3. at the least 15
Step-by-step explanation:
1. 250 is dependent variable
2. 5,150-2400=2750
2750/250=11
3.2400+250x=6000
6000-2400=3600
250x=360
3600/250
x=14.4
you need to sell at least 15
3. Nutrition labels. The nutrition label on a bag of potato chips says that a one ounce (28 gram) serving of potato chips has 130 calories and contains ten grams of fat, with three grams of saturated fat. A random sample of 35 bags yielded a sample mean of 134 calories with a standard deviation of 17 calories. a. Calculate the 95% confidence interval of for this random sample. Then interpret this interval.
Answer:
The 95% confidence interval of for this random sample is between 128.16 calories and 139.84 calories. This means that we are 95% that the mean number of calories for all bags of potato chips is in this interval.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 35 - 1 = 34
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 34 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.0322
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 2.0322\frac{17}{\sqrt{35}} = 5.84[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 134 - 5.84 = 128.16 calories
The upper end of the interval is the sample mean added to M. So it is 134 + 5.84 = 139.84 calories
The 95% confidence interval of for this random sample is between 128.16 calories and 139.84 calories. This means that we are 95% that the mean number of calories for all bags of potato chips is in this interval.
1. The average length of all the trout in a river is 60 cm. This data summary represents a ____________________(parameter/statistic).
2. If the Hamilton High School freshman class is the sample in a statistical study, then which is not a possible for the study?
A. The student body of Hamilton High School
B. The students in Hamilton High School's district
C. The students in Ms. Anderson's science class
D. All freshman students in the state
Answers:
ParameterC. The students in Ms. Anderson's science class==========================================================
Explanation for problem 1
If all we're concerned with are the trout in this river, and this river only, then we are measuring the parameter population mean value of 60 cm. Parameters always go with populations; while statistics go with samples.
A quick way to remember:
parameter and population both start with pstatistic and sample both start with s----------------------------------------------------------
Explanation for problem 2
This question seems to be missing a key word. The portion that reads "then which is not a possible for the study?" seems to have a missing word where the blank is shown below
then which is not a possible _____ for the study?
I think "population" should be put into the blank. If that's the case, then choices A, B, and D are all possible populations here. They are larger than the sample of freshmen at this high school. Notice how the students in Ms. Anderson's class is a smaller set compared to the set of all freshmen at Hamilton High School. The sample must always be smaller than the population, or phrased another way, the population must always be larger than the sample.
So this is why choice C is the answer.

Agnete consumes 1.68 grams of caffeine in a week.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
We know that Agnete drinks 3 cups of drip coffee every day, and each cup contains 8 oz of coffee, which is equivalent to 80 mg of caffeine.
To find out how many grams of caffeine Agnete consumes in a week, we can start by calculating the total amount of caffeine she consumes in a day:
Total caffeine in a day.
= 3 cups x 80 mg/cup
= 240 mg
Then, we can multiply this value by 7 to find the total amount of caffeine she consumes in a week:
Total caffeine in a week = 240 mg/day x 7 days/week = 1680 mg
To convert milligrams (mg) to grams (g), we divide by 1000:
Total caffeine in a week = 1680 mg / 1000 = 1.68 g
Therefore,
Agnete consumes 1.68 grams of caffeine in a week.

Answer:
[tex]A=12[/tex]
Step-by-step explanation:
The formula to find the area of a trapezoid is,
[tex]A=(\frac{b_1+b_2}{2})(h)[/tex]
Where ([tex]b_1[/tex]) and ([tex]b_2[/tex]) represent the two bases of the trapezoid, and ([tex]h[/tex]) represents the hieght of the figure. As one can see on the coordinate plane,
[tex]b_1=2\\\\b_2=4\\\\h=4[/tex]
Substitute in the given values, and solve,

what is the difference in length between the longest ski Trail and the shortest ski trail that the longest ski Trail is 3 1/8 the shortest ski Trail is 1 3/8
The difference in length between the longest ski trail and the shortest ski trail is 7/4.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have:
Length of the longest ski trail = 3 1/8 = 25/8
Length of the shortest ski trail = 1 3/8 = 11/8
Difference in length between the longest ski trail and the shortest ski trail:
= 25/8 - 11/8
= 14/8
= 7/4
Thus, the difference in length between the longest ski trail and the shortest ski trail is 7/4.

2 questions...both need answers
1. The length of a rectangle is 1 less than 4 times the width. If the perimeter is 118 ft., find
the length and the width. You must solve algebraically.
2. Ally scored 5 more than 7 times as many points as Gaelle during the weekend
basketball game. If they scored 45 points, how many did Ally score?
You must solve algebraically.
Answer:
Step-by-step explanation:
1.
L=4W-1
P=2(L+W)=118, using L from above makes this
2(4W-1+W)=118,
2(5W-1)=118
5W-1=59
5W=60
W=12, and since L=4W-1
L=4(12)-1
L=47
So the length is 47ft and the width is 12ft
2.
A=7G+5
7G=A-5
G=(A-5)/7, and we are told A+G=45, using G=(A-5)/7 gives us
A+(A-5)/7=45
(7A+A-5)/7=45
(8A-5)/7=45
8A-5=315
8A=320
A=40
So Ally scored 40 points.

Answer:
10/117 or 8.55% or 0.09
Step-by-step explanation:
5/13 x 2/9 = 10/117
The probability you get orange juice and a ham sandwich is,
⇒ 10/117
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one
Given that;
In a cooler there are 5 orange juices, 2 apple juices and 6 grape juices. In a large bag there are 2 ham sandwiches and 7 turkey sandwiches.
Hence, Total number of juice in a cooler = 5 + 2 + 6 = 13
And, Total number of sandwiches = 2 + 7 = 9
Thus, The probability you get orange juice and a ham sandwich is,
⇒ 5 / 13 × 2 / 9
⇒ 10/117
