Answer:C.4
Step-by-step explanation:
Answer:
It's B.3
Step-by-step explanation:
Substitution. With the equation Y= 9x+28 and Y= 11x+22, you substitute the x-factor with '3'. Which will give you
Y= 9(3)+28 Y= 11(3)+22
Y= 27+28 Y= 33+22
Y= 55 Y= 55
A bakery offers a sale price of $2.60 for 4 muffins. What is the price per dozen?
Answer:
31.2
Step-by-step explanation:
2.60 times 4 is 10.4.
4 times 3 is 12
10.4 times 3 is 31.2
Answer:
Hello!
A dozen muffins would cost $7.80
----------------------------------------------------------------------------------------------------------------
So if you took for muffins the price would be $2.60 But thats not a dozen
Dozen = 12 muffins
So for 12 muffins you would have to take 4 muffins times 3 (4x3=12)
So to find the price you need to do $2.60 x 3 and you would get $7.80

write the equation that describes the line in slope-intercept form. slope = 5 point (2,-4)
PLEASE HELP!!!
Answer:
y = 5x - 14
slope intercept form is y = mx + b
m = slope
after substituting 5 in for m you end up with y = 5x + b
you substitute (2, -4) for x and y
-4 = 5(2) + b
next step is to solve for b.

A container is 8/9 kg of berries is 2/3 full, how many kg can the container hold
Answer:
1.33kg of berries
Step-by-step explanation:
A container is 8/9 kg of berries is 2/3 full, how many kg can the container hold
2/3 of a container = 8/9kg
To get the amount of kg the container can hold, we will write;
1 container = x kg
Divide both expressions
2/3 = 8/9x
Cross multiply
2 * 9x = 3*8
18x = 24
x = 24/18
x = 1.33kg
Hence the container will hold 1.33kg of berries

A set of exam marks has mean 70 and median 65 marks. It is decided to subtract 10 from all the marks. For the new set of marks, what is the median?
Answer:
For the new set of marks, the median is of 55
Step-by-step explanation:
The median is the halfway point of a dataset, that is, the value that separates the lower 50% of the data set from the upper 50%.
In a data set, if we subtract or add all marks by x, the median will be subtracted or added by x.
In this question, we have that:
Median 65
From all marks, 10 is subtracted.
So, for the new set of marks, the median is of 65 - 10 = 55

Which ratios form a proportion?
4/11 and 6/13
4/10 and 10/25
3/5 and 9/25
4/9 and 9/4
Answer:
Step-by-step explanation:
Now, in order for it to be a proportion, both the number and the denominator must turn to the other number by the same method. I'll clarify when we do the steps.
So, the first one is 4/10 and 10/25
The first thing that you would do is divide 10 by 4, and then 25/10
When you do that, it turns out that they both equal 2.5. This means that both the number and denominator go to the new number with the same method, multiplying by 2.5
So, the answer would be A

What is the greatest number of individual eggs he can buy for $50.00?
192182✓180150182 eggs is the right answer.Step-by-step explanation:
Cost of 12 eggs are $3.29
Cost of 1 egg is ($3.29/12)=$0.27
Juan has $50.00
Therefore, he could buy ($50/$0.27)=182 eggs

Mean= 14.47368Meadian= 15Mode= 17Range= 7Anna, Bertie and Carl share £135 in the ratio 5 : 4 : 6.
How much does Carl get?
Answer:
Anna gets £45, Bertie gets £36 and Carl gets £54
Step-by-step explanation:
→ Add the ratios together
5 + 4 + 6 = 15
→ Divide the amount by the total of ratios
135 ÷ 15 = 9
→ Multiply 9 by each part of the ratio
Anna = 5 × 9 = £45
Bertie = 4 × 9 = £36
Carl = 6 × 9 = £54

A large sleep study involving over 5000 American teenagers examined how many hours the participants slept on the weekend. The nightly sleep times were distinctly non-normal with a mean of 10 hours and a standard deviation of 2 hours. Suppose we take a random sample of 100 nightly sleep times from this population. We can assume that the times in the sample are independent. What is the probability that the mean of these 100 sleep times is farther than 0.4 hours away from the population mean?
a) 0455
b) .02
c) 1
d) .02275
Answer:
.05
Step-by-step explanation:
Khan
Using the normal distribution and the central limit theorem, it is found that the probability that the mean of these 100 sleep times is farther than 0.4 hours away from the population mean is:
a) 0.0455Normal Probability DistributionIn a normal distribution 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]
It 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, which is the percentile of X. By the Central Limit Theorem, the sampling distribution of sample means of size n, as long as n > 30, is approximately normal and has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].In this problem:
Mean of 10 hours, hence [tex]\mu = 10[/tex].Standard deviation of 2 hours, hence [tex]\sigma = 2[/tex].Sample of 100, hence [tex]n = 100, s = \frac{2}{\sqrt{100}} = 0.2[/tex].We want the probability that the mean is farther than 0.4 hours away from the population mean, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem:
[tex]Z = \frac{0.4}{s}[/tex]
[tex]Z = \frac{0.4}{0.2}[/tex]
[tex]Z = 2[/tex]
The probability is P(|Z| > 2), which is 2 multiplied by the p-value of Z = -2.
Z = -2 has a p-value of 0.0275.2 x 0.0275 = 0.0455Hence, option A is correct.

Color: red, blue, black, green, or silver
Top: sunroof or no sunroof
Jordan says that he has a total of 2 + 2 + 5 + 2, or 11, possible vehicle choices. What is Jordan’s error?
He should have multiplied the sum by 4.
He should have added only the choices for type and transmission.
He should have multiplied only the choices for type and transmission.
He should have multiplied the choices, instead of adding them.
