A baker uses 3/4 teaspoon cinnamon for every 2/3 can of pumpkin when making pumpkin muffins. How much cinnamon does the baker need for each can of pumpkin?
Answer:
9/8 teaspoon
Step-by-step explanation:
The original ratio is 0.75:0.66 (x:y). We need to find x when y = 1.
0.66*1.5 = 1
So, if the original y was multiplied by 1.5 to get 1 (which we need) then we can multiply the original x to get our answer.
0.75*1.5 = 1.125
Convert into fractional form:
1.125 = 9/8
Your answer is 9/8 teaspoon of cinnamon per one can of muffins.

At the end of the month, a restaurant manager used the total food sales for the month and the total number of customers for the month to calculate the mean about spent per customer during that month was $12.59. Is this value a statistical or a parameter? Explain.
Answer:
Step-by-step explanation:
It is a parameter, I think. The population is limited to all of the restaurant's customers. Presumably they don't come in to look at the waitresses -- although that might happen. They are there for coffee donuts or a meal, so they are spending money, that's what all of them have in common.
So the population is very confined and very well defined.
The owner is finding a mean. Anything like this is a parameter which defines some aspect of the population.

What would be the first step to solve this equation x - 5 (x-1) = x - (2x- 3 )
Graph x > 1. WILL MARK BRAINLY
You have the correct answer. The graph of x > 1 involves an open hole at 1 and the shading is to the right. This visually describes any x value that is greater than 1. So for instance, x = 2 works but x = 0 does not.
The open hole means we exclude x = 1 itself from the shaded solution set.

Which, if any , of the following equality’s is incorrect ?
Answer:
x = 32 is incorrect
Step-by-step explanation:
[tex]32 = \frac{1}{2} (x + 16) \\ \\ 32 \times 2 = x + 16 \\ \\ 64 = x + 16 \\ \\ x = 64 - 16 \\ \\ x = 48 \\ \\ y =360-(48+114 + 16) \\ \\ y =360-178 \\ \\y = 182 \\ \\ 4 \times n = 6 \times 3 \\ \\ n = \frac{18}{4} \\ \\ n = 4.5[/tex]
In a basketball game, Phil scored three times as many points as Fred. Together they combined to score 56 points. How many points did Phil score?
Answer:
Step-by-step explanation:
X= Fred
56=x+3x

Cristian divides 6 cups of fruit juice equally among 8 friends. Two of his friends don't drink the juice. How much juice is left over?
A. 3/4 cup
B. 1.5 cups
C. 4 1/2 cups
D. 5.25 cups
Why?
please help
Answer:
B. 1.5 cups
Step-by-step explanation:
6/8 = 0.75
each person gets 0.75 each
Since 2 people chose not to drink the juice. the left overs would be 0.75*2
0.75*2=1.5
A complex electronic system is built with a certain number of backup components in its subsystems. One subsystem has four identical components, each with a probability of 0.2 of failing in less than 1000 hours. The subsystem will operate if any two of the four components are operating. Assume that the components act independently.a) Find the probability that exactly two of the four components last longer than 1000 hours.b) Find the probability that the subsystem operates longer than 1000 hours.
Answer:
a) 0.1536 = 15.36% probability that exactly two of the four components last longer than 1000 hours.
b) 0.9728 = 97.28% probability that the subsystem operates longer than 1000 hours.
Step-by-step explanation:
For each component, there are only two possible outcomes. Either they fail in less than 1000 hours, or they do not. The probability of a component failing in less than 1000 hours is independent of any other component. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
One subsystem has four identical components, each with a probability of 0.2 of failing in less than 1000 hours.
Four components means that [tex]n = 4[/tex]
Probability of 0.2 of failling means that 1 - 0.2 = 0.8 probability of not failling, so [tex]p = 0.8[/tex]
a) Find the probability that exactly two of the four components last longer than 1000 hours.
This is [tex]P(X = 2)[/tex]. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{4,2}.(0.8)^{2}.(0.2)^{2} = 0.1536[/tex]
0.1536 = 15.36% probability that exactly two of the four components last longer than 1000 hours.
b) Find the probability that the subsystem operates longer than 1000 hours.
It will operate if at least two compoents last longer than 1000 hours. So
[tex]P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{4,2}.(0.8)^{2}.(0.2)^{2} = 0.1536[/tex]
[tex]P(X = 3) = C_{4,3}.(0.8)^{3}.(0.2)^{1} = 0.4096[/tex]
[tex]P(X = 4) = C_{4,4}.(0.8)^{4}.(0.2)^{0} = 0.4096[/tex]
[tex]P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4) = 0.1536 + 0.4096 + 0.4096 = 0.9728[/tex]
0.9728 = 97.28% probability that the subsystem operates longer than 1000 hours.

For the problem y=-(-x^2/2)-2x; [-3,1], find the value of c that satisfies the Mean Value Theorem.
Answer:
We seek to verify the Mean Value Theorem for the function
f(x)=3x2+2x+5
on the interval
[−1,1]
The Mean Value Theorem, tells us that if
f(x)
is differentiable on a interval
[a,b]
then ∃
c∈[a,b]
st:f'(c)=f(b)−f(a)b−a
So, Differentiating wrt
x
we have:
f'(x)=6x+2
And we seek a value
c∈[−1,1]
st: f'(c)=f(1)−f(−1)1−(−1)
∴6c+2=(3+2+5)−(3−2+5)2
∴6c+2=42
∴6c+2=2
∴6c=0
∴c=0
