Answer:
12) z = 64
15) q = 75
Step-by-step explanation:
12) 40/65 = z/10⁴
Cross Multiply
65 × z = 40 × 104
65z = 4160
z = 4160 / 65
z = 64
15)32.5/25 = 97.5/q
Cross Multiply
25 × 97.5 = 32.5× q
q = 25 × 97.5/32.5
q = 2437.5 /32.5
q = 75

The times to pop a regular bag of microwave popcorn without burning it are Normally distributed with a mean time
of 140 seconds and a standard deviation of 20 seconds. The times to pop a mini bag of microwave popcorn
without burning it are Normally distributed with a mean time of 90 seconds and a standard deviation of 15
seconds. Suppose two independent random samples, 25 of each, are taken and the mean popping times are
calculated. Let R = the popping time of a randomly selected regular-sized bag and M = the popping time of a mini-
sized bag. Which of the following best describes the standard deviation of the sampling distribution of 5-7 ?
1 second
5 seconds
25 seconds
35 seconds
Answers
Answer:
3
Step-by-step explanation:
Approximately normal with mean of 140 seconds and standard deviation of 10 seconds.
What is Central Limit Theorem:?The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean.
here, we have,
Given,
In the question:
The times to pop a regular bag of microwave popcorn without burning it are Normally distributed with a mean time of 140 seconds and a standard deviation of 20 seconds. The times to pop a mini bag of microwave popcorn without burning it are Normally distributed with a mean time of 90 seconds and a standard deviation of 15 seconds.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean of 140, standard deviation of 20, sample of 4:
By the Central Limit Theorem, the distribution is approximately normal.
Mean is the same, of 140.
n = 4 , σ = 20, thus:
s = σ /√n
= 20/√4
= 10
Thus, the correct answer is:
Approximately normal with mean of 140 seconds and standard deviation of 10 seconds.

of her total website-design earnings each week, how much will she save in 4 weeks?
Answers
42.5 * 20 = 850
So she earns $850 per week.
Mallory saves half of that amount she would have $425 per week.
In 4 weeks she would have:
425 * 4 = 1700
Mallory will save $1,700 in four weeks.
Answer:
I believe it's 17000
Step-by-step explanation:
42.50 x 20 = 850
850 x 5 (5 business days) = 4250
4250 x 4 (4 weeks) = 17000

When Larry tried to teach his dog Allegra to speak, he gave him 1 sausage - and he barked once. When he
gave him 2 sausages, he barked twice. Then he gave him 3 sausages, and he barked three times.
Larry predicted that Allegra would bark four times if he gave him 4 sausages.
What type of reasoning did Larry use to make his prediction?
A. Deductive reasoning
B. Inductive reasoning
C. Indirect reasoning
D. Circular reasoning
Answers
In case of : Allegra barking n = 4 times, when given 4 sausages - Inductive Logic is used.
Given : Allegra barks once & twice & thrice, when Larry gives him 1 & 2 sausages respectively.
So, later he assumes that he would bark 4 times, if given four sausages
Deductive Reasoning is when conclusion related to particular is drawn, based on general universal. Eg : All men are mortal, Ram is a man. Ram is mortal. Inductive Reasoning is when a generalised conclusion is drawn, based on specific case. Eg : Law of gravity based on apple falling. Allegra's case of barking n times for n sausages (1, 2,3 ...) is further generalised for other positive numbers & hence 4. Indirect Reasoning relates two events. If A is true leads to B is true, then B is false implies A has also been false. Circular Reasoning is a logical fallacy of beginning with an already assumed true statement.To learn more, refer https://brainly.com/question/2848937?referrer=searchResults
4x+16= 64, solve for x
Answers
Answer:
x=12
Step-by-step explanation:
4x+16=64
to isolate x, take 16 from both sides
4x+ 16(-16)=64-16
4x=48
divide 4 on each side
4x/4=x
48/4=12
x=12
The solution of the equation 4x+16= 64 is x = 12.
What is the solution for an equation?The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of those variable would give a true mathematical statement.
For this case, we've to solve for x, the equation [tex]4x + 16 = 64[/tex]
Subtracting 16 from both the sides:
[tex]4x + 16 - 16 = 64 - 16\\4x + 0 = 48\\4x = 48[/tex]
4x is actually 4 times x, and is written in short, where the multiplication sign is hidden. This is usually done when variables like x,y are there.
Dividing both the sides by 4, we can get x on one side, and rest of the constant values on the other side.
[tex]\dfrac{4x}{4} = \dfrac{48}{4}\\\\1 \times x = 12\\x = 12[/tex]
(since 1 times any number is that number itself, and as x represents a number, so we got 1 times x =x).
Thus, the solution of the equation 4x+16= 64 is x = 12.

Answers
Answer:
45 degrees
Step-by-step explanation:
Here, we want to get the value of the acute angle
From the question, we have it that the sin of the acute angle equals its cosine
Recall;
cos A = sin (90-A)
Hence, if A is 45, then Cos A and Sine A will be the same
This means the value of theta which is the acute angle is 45 degrees

What is Expression?An expression is combination of variables, numbers and operators.
To write the expression in standard form, we need to simplify it by multiplying the two factors using the distributive property of multiplication:
(2x + 5)(x + 1) = 2x² + 2x + 5x + 5

A company with 10,000 employees would like to know whether their employees think that they are paid enough. Do you think asking the question to 200 employees from the same department is most representative of all the employees? Explain your reasoning.
Answers
Answer: It is not.
Step-by-step explanation:
The salaries paid to the various departments of a company are usually different as some departments get paid more than others. For instance, in a manufacturing company, the R&D department would on average, get paid more than members of the Cleaning department.
Asking members of only one department therefore, about their pay satisfaction would not bring about a reasonable result because it would not be indicative of the thoughts of members of the other departments who are not being paid the same.
