Answer:

x/4 -6.5

Step-by-step explanation:

(3x−1)−2.75(x+2)

Use the distributive property to multiply −2.75 by x+2.

=3x−1−2.75x−5.5

Combine 3x and −2.75x to get 0.25x.

=0.25x−1−5.5

Subtract 5.5 from −1 to get −6.5.

=0.25x - 6.5

=x/4 - 6.5

Step-by-step explanation:

It says "given that you are in Sacramento", so hint: only look at the Sacramento row. Ignore everything else, you don't need it.

Then it asks what is the probability of a clear day, so you look at the "Clear" column from the Sacramento row. That would be 17 days.

Lastly, you just simply divide from the total days. 17/30 = 0.57

Answer:

Step-by-step explanation:

The total number of candies in the bag is 4 cherry + 8 orange + 2 lemon + 8 grape + 6 sour raspberry = 28 candies.

The probability of drawing a cherry on the first draw is 4/28, and the probability of drawing a sour raspberry on the second draw given that a cherry was drawn first is 6/27 (since there are 27 candies left in the bag after the first draw).

The probability of drawing a sour raspberry on the first draw is 6/28, and the probability of drawing a cherry on the second draw given that a sour raspberry was drawn first is 4/27.

Therefore, the probability of drawing one cherry and one sour raspberry in either order is:

(4/28) * (6/27) + (6/28) * (4/27) = 24/756 + 24/756 = 48/756

So the probability of drawing one cherry and one sour raspberry in either order is 48/756.

The number of defectives follows binomial distribution with parameters (n,p) and if n>30 then binomial distribution goes to the Normal' approximation.

Given that,

We have to find which of the following approximation approaches is adequate in a test of the equality of the percent defectives from two populations when the sample sizes are big (> 30).

We know that,

The normal curve is roughly followed by the sample distribution of averages or proportions from numerous independent experiments. The population value that corresponds to a sample proportion or average is its expectation.

Therefore, the number of defectives follows binomial distribution with parameters (n,p) and if n>30 then binomial distribution goes to the Normal' approximation.

The correct answer is:

**C) 0.28**

The sum of deviations refers to the sum of the differences between individual data points and the mean of the dataset. In any dataset, the sum of deviations from the mean will always equal 0.

This is because, when calculating the mean, you sum all the data points and then divide by the number of data points. The mean represents the "middle" or "balance" point of the dataset. When you add up the differences between each data point and the mean, the positive and negative deviations will cancel each other out, resulting in a sum of 0.

So, any non-zero value for the sum of deviations is impossible. In this case, 0.28 is the only non-zero value.

Answer:

Answer: The maximum value of the function is 4

Answer:

Step-by-step explanation:

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis).

Given that the slope of the line is m = 4/6, we can substitute it into the equation.

We know that the line passes through the point (1, -1), so we can use that point to find the value of b.

Plugging in the point (1, -1) into the equation, we get:

-1 = (4/6)(1) + b

Solving for b, we get:

b = -1 - (4/6) = -1 - 2/3 = -5/3

So the equation of the line is:

y = (4/6)x - (5/3)

which can be rewritten as

y = (2/3)x - (5/3)

this line is the equation of the line you are looking for.

Answer: Last graph, the one with the points (1, 2), (2, 3), (3, 4), and (4, 5)

Step-by-step explanation:

We have the equation y = x + 1

Now we can replace x by different values to get pairs (x, y).

if x = 1, we have:

y = 1 + 1 = 2

then we have the pair (1, 2)

if we have x = 2, then:

y = 2 + 1 = 3

Then we have the pair (2, 3)

So we need to find the graph that has these points.

The only graph that has the points (1, 2) and (2, 3) is the last graph.

Answer:

7 - 2m can be translated to "7 minus two times m" or "the difference between 7 and twice m".

3(m + 2) = 15 can be translated to "three times the sum of m and 2 is equal to 15" or "the product of 3 and the sum of m and 2 is 15".

To solve the equation, we can start by distributing the 3 on the left side:

3(m + 2) = 15

3m + 6 = 15

Then, we can subtract 6 from both sides:

3m + 6 - 6 = 15 - 6

3m = 9

Finally, we can divide both sides by 3:

3m/3 = 9/3

m = 3

Therefore, the solution to the equation 3(m + 2) = 15 is m = 3.

5m - m(2 - m) can be translated to "5m minus the product of m and the difference between 2 and m" or "the difference between 5m and m times the quantity 2 minus m".

To simplify the expression, we can use the distributive property to expand the second term:

5m - m(2 - m) = 5m - 2m + m^2 = m^2 + 3m

Therefore, the simplified expression is m^2 + 3m.

G does not satisfy the identity element property, it is not a group.

To determine if G = {x ∈ R | x^2 = 0} is a group, we need to verify the group axioms:

1. Closure: For any

a, b ∈ G,

the operation (addition) should produce another element in G.

In this case, let's consider a = b = 0. We have 0^2 = 0, which means 0 is an element of G.

So, closure is satisfied.

2. Associativity: For any

a, b, c ∈ G, (a + b) + c = a + (b + c).

Addition in the real numbers is associative, so associativity holds.

3. Identity Element: There should exist an identity element e ∈ G such that for any

a ∈ G, a + e = e + a = a.

However, there is no element in G that satisfies this property.

Since 0 is the only element in G, adding any element to 0 does not change the result.

Therefore, there is no identity element, and G does not satisfy the identity element property.

4. Inverse Element: For any

a ∈ G,

there should exist an inverse element b ∈ G such that a + b = b + a = e.

Again, since there is no identity element in G, there are no inverse elements for the elements in G.

Since G does not satisfy the identity element property, it is not a group.

Chris's research costs can be calculated using the percentage increase in his return and the desired hourly wage. The cost of his research will be $375.45. As a result of the research, Chris's return will increase by $257.96. On a strict economic basis, Chris should perform the proposed research as the increase in return outweighs the cost.

To calculate the cost of Chris's research, we need to determine the amount of time he devotes to it. Let's assume he spends x hours on research. The cost of his research can be calculated by multiplying his desired hourly wage ($31.00) by the number of hours spent:

Cost of research = $31.00 × x

Now, to find x, we need to consider the percentage increase in Chris's return. The percentage increase is given as a range from 6.1% to 8.7%. Let's take the average of these percentages, which is (6.1% + 8.7%) / 2 = 7.4%. This means Chris's return will increase by 7.4% as a result of the research.

To find x, we can set up the following equation:

1.074 × initial return = final return

Simplifying the equation, we have:

initial return = final return / 1.074

Since the initial return is given as a percentage, we can express it as 100% (or 1 in decimal form). The final return can be expressed as 100% + 7.4% = 107.4% (or 1.074 in decimal form).

So, the equation becomes:

1 = 1.074 / initial return

Solving for initial return, we find:

initial return = 1.074

Now, we can substitute the initial return into the equation for cost of research:

Cost of research = $31.00 × x = $31.00 × (initial return - 1) = $31.00 × (1.074 - 1) = $31.00 × 0.074 = $2.294

Rounding this to the nearest cent, the cost of Chris's research is approximately $2.29.

Next, to find the increase in Chris's return as a result of the research, we can calculate:

Increase in return = final return - initial return = 1.074 - 1 = 0.074

Finally, we can calculate the increase in dollars:

Increase in dollars = Increase in return × initial return = $31.00 × 0.074 ≈ $2.30

Rounding this to the nearest cent, Chris's return will increase by approximately $2.30.

On a strict economic basis, Chris should perform the proposed research. The cost of research is $2.29, while the increase in return is $2.30. Therefore, the increase in return outweighs the cost, resulting in a positive net benefit.
