A bakery sold 154 mocha cupcakes in a day, which was 35% of the total number of cupcakes sold that day. How many total cupcakes did the bakery sell that day?
Answer:
440
Step-by-step explanation:
If we have the information that 154 mocha cupcakes = 35% of the total cupcakes sold on a certain day, then to find the total number of cupcakes old that day, we can set up a simple proportion.
So, with x = the unknown number of total cupcakes
35% = 154 / x
==>
35 / 100 = 154 / x
We can use cross-multiplication to simplify to ==>
35x = 15,400
Now we divide both sides by 35 to isolate our variable ==>
x = 440
So, the total number of cupcakes sold that day (100%) was 440 cupcakes

Suppose A< - 1 what must be true about the value of b so that ab< a
Answer:
b must be positive
Step-by-step explanation:
if a is less than -1
that means to get smaller numbers
b needs to be positive
so that when a is multiplied by b you would have
numbers that are more negative
Answer:
b > 1
Step-by-step explanation:
Given:
a < -1 ab < aSubstituting a = -1 into ab < a
⇒ (-1)b < -1
⇒ -b < -1
⇒ b > 1
If a < -1 then a is negative. If ab < a then ab is also negative.
In order for ab to be negative (when a is negative) b must be positive.
For ab < a then b > 1.
Proof
If b = 0.5 and a = -1.5 then ab = -0.75
As -0.75 > -1.5 then ab > a so this cannot be true.
If b = 1.5 and a = -1.5 then ab = -2.25
As -2.25 < -1.5 then ab < a so this is true.
Therefore b > 1

Sharon has a soap and water mixture that is 36% soap. How many liters of water must
Sharon add to 5 liters of this mixture to make a solution that is 12% soap?
The volume of water that Sharon must add to the 5 liters mixture to make a solution that is 12% soap is 10 liters
Dilution lawFrom the question, we are to determine how many liters of water must Sharon add to 12% soap solution
Using the dilution law formula,
C₁V₁ = C₂V₂
Where C₁ is the initial concentration
V₁ is the initial volume
C₂ is the final concentration
and V₂ is the final volume
From the given information,
C₁ = 36%
V₁ = 5 liters
C₂ = 12%
V₂ = ?
Putting the parameters into the equation, we get
36 × 5 = 12 × V₂
180 = 12V₂
∴ V₂ = 180 / 12
V₂ = 15 liters
This means the final volume of the solution will be 15 liters.
Volume of water that must be added = V₂ - V₁
Volume of water that must be added = 15 liter - 5 liters
Volume of water that must be added = 10 liters
Hence, the volume of water that Sharon must add to the 5 liters mixture to make a solution that is 12% soap is 10 liters.

Answer:
The answer is C (0.30) are NOT going to particulate
Step-by-step explanation:
We can find the answer by simply putting all of the results into order, which gives the following for the non-participants:
28: 6's
27: 7's
29: 8's
15: 9's
Now to find the answer, we must know the total amount of results, which I found to be 250. We also need to know the total amount of non-participants there are, which is 99. So if we take 99 and divide it by 250 (99/250); we get 0.396. Although this isn't the exact answer, it is the closest.
To further prove that this should be right, Yuri found 60% of students to participate, which leaves around 40% left to not participate. So this should be right.

Choose 1 answer:
Answer:
0.02< P-value<0.04
Step-by-step explanation:
Since this P-value is less than the usual significance level of 0.05, we would reject the null hypothesis and conclude that there is evidence of a difference between the true population mean and 36 at the 0.05 level of significance.
What is hypothesis testing?Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.
It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.
We have,
To find the P-value for Jasper's test, we need to use the t-distribution with degrees of freedom (df) equal to the sample size minus one,
which is 16-1=15 in this case.
Using a t-table or a calculator, we can find that the two-tailed P-value for t=2.4 with df=15 is approximately 0.029.
This means that if the null hypothesis is true (i.e., if the true population mean is 36), the probability of observing a sample mean as extreme as or more extreme than the one obtained by Jasper is 0.029.
Thus,
Since this P-value is less than the usual significance level of 0.05, we would reject the null hypothesis and conclude that there is evidence of a difference between the true population mean and 36 at the 0.05 level of significance.

The question is an illustration of probability, and the value of P(B|C) is P(B|C) = 9/24 =0.38
How to determine the probability P(B|C)?The table is given as:
C D Total
A 15 21 36

n(B and C) = 9
n(C) = 24
So, the equation becomes
P(B|C) = 9/24
