Answer:

Step-by-step explanation:

20:50

Step-by-step explanation:

Given,

3 coffee + 2 muffins = $7

and

2 coffees + 4 muffins = $8

let the coffee be x and muffins be y.

so now, we got

3x + 2y = $7 -----------(eqⁿ 1)

2x + 4y = $8 -------------(eqⁿ 2)

multiply (eqⁿ 1) by 2

we got,

2(3x + 2y = $7) = 6x + 4y = $14 -----(eqⁿ 3)

now, subtract (eqⁿ 2) from (eqⁿ 3)

we got,

(6x - 4y = $14) - (2x + 4y = $8)

we got,

4x = $6

x = 6/4 = $1.5

to get value of y put the value of x in eqⁿ2

we got,

→ 2(1.5) + 4y = $8

→ 3 + 4y = 8

→ 4y = 8 - 3 = 5

→ y = 5/4 = $1.25

hence,

value of one coffee = $1.5

value of one muffin = $1.25

Step-by-step explanation:

If there were only 2 options, all the people who didn't pick one chose the other one.

So if 25% of the people voted for the aquarium the remaing 75% voted for the zoo.

Since three times as many people voted for the zoo, we can see that 120/3=40, so 40 people chose the aquarium.

To find the total number of students, we add 120 and 40 to get 160

Deon drove 270 miles.

Let x be the number of miles driven.

The total cost is 20.95 + 0.74x = 221.49

Subtracting 20.95 from both sides gives 0.74x = 200.54

Dividing both sides by 0.74 gives x = 270 miles

So the answer is 270

Answer:

271 miles

Step-by-step explanation:

The equation to find the total cost is

C = 20.95 + .74 m  where m is the number of miles

221.49 = 20.95 +.74m

Subtract 20.95 from each side

221.49 -20.95 = 20.95-20.95 +.74m

200.54 = .74m

Divide each side by .74

200.74/.74 = m

271 = m

The candy distributor needs to use 30 kilograms of 10% fat-content chocolate and 70 kilograms of 50% fat-content chocolate to create 100 kilograms of a 14% fat-content chocolate.

To solve this problem, we can use the method of mixture problems, which involves setting up a system of equations. Let x be the number of kilograms of the 10% fat-content chocolate and y be the number of kilograms of the 50% fat-content chocolate.

We have two equations based on the fat content and the total weight of the mixture:

0.1x + 0.5y = 0.14(100) (equation for fat content)

x + y = 100 (equation for total weight)

We can solve this system of equations using substitution or elimination. Using substitution, we can solve for x in terms of y from the second equation and substitute it into the first equation:

x = 100 - y

0.1(100 - y) + 0.5y = 0.14(100)

10 - 0.1y + 0.5y = 14

0.4y = 4

y = 10

Then we can substitute y = 10 back into the equation for x and get:

x = 100 - y = 100 - 10 = 90

To determine the number of significant discriminant functions and their relative discriminating power in a dataset, a discriminant analysis needs to be performed. Discriminant analysis is a statistical technique used to classify objects or individuals into different groups based on a set of predictor variables.

The number of significant discriminant functions is equal to the number of distinct groups or classes in the dataset minus one. Each discriminant function represents a linear combination of the predictor variables that maximally separates the groups or classes.

The relative discriminating power of each discriminant function can be assessed by examining the Wilks' lambda value or the eigenvalues associated with each function. Wilks' lambda represents the proportion of total variance unexplained by each discriminant function. Smaller values of Wilks' lambda indicate higher discriminating power.

To determine the exact number of significant discriminant functions and their relative discriminating power in a specific dataset, the discriminant analysis needs to be performed using statistical software or tools specifically designed for this analysis.

The new variance is 0.0625 / n

We can use the following formula to calculate the variance of a data set

variance = (sum of (x - mean)^2) / (number of data points)

where x is a data point and mean is the mean of the data set.

If the mean cost of a box of Cheerios Oat Crunch is $4.00 and the variance is 0.35, we can find the standard deviation as follows

standard deviation = square root of variance = sqrt(0.35) = 0.59

Now, if the price increases by 25 cents a box, the new mean cost will be

new mean = $4.00 + $0.25 = $4.25

To find the new variance, we need to calculate the sum of (x - mean)^2 for the new data set and divide by the number of data points. Let's assume we are still considering the same number of boxes.

sum of (x - mean)^2 = [(4.25 - 4)^2 × n] = 0.0625 × n

where n is the number of data points.

Therefore, the new variance can be calculated as

new variance = (sum of (x - mean)^2) / (number of data points) = 0.0625 / n

D. The angles are congruent (same measure) and the side lengths are proportional (consistent ratios) in a dilation with a scale factor not equal to 1. therefore option D is correct.

When a dilation with a scale factor not equal to 1 is performed, the angles and side lengths of the pre-image and the corresponding image have a specific relationship.

The correct answer is D. The angles are congruent, meaning they have the same measure, and the side lengths are proportional, meaning they have a consistent ratio.

In a dilation, the angles of the pre-image and the corresponding image remain the same. They are congruent because the dilation only changes the size of the shape, not the angles.

On the other hand, the side lengths of the pre-image and the corresponding image are proportional. This means that the ratios of corresponding side lengths are equal. For example, if one side of the pre-image is twice as long as another side, the corresponding side in the image will also be twice as long.

So, in summary, the angles are congruent (same measure) and the side lengths are proportional (consistent ratios) in a dilation with a scale factor not equal to 1.

To prove that X is an ordered set in which every closed interval is compact, then X has the least upper bound property, let A be a nonempty set in X that is bounded above. Let S be the set of all upper bounds of A. Then S is nonempty because X has the least upper bound property.

To show that S has a least upper bound, we must show that S is bounded above and that the least upper bound property holds for S.To show that S is bounded above, let b be any element of A. Since b is an upper bound of A, S contains b, so b ≤ s for every s in S. Therefore, S is bounded above. Let c be the least upper bound of S. We claim that c is the least upper bound of A. Let a be any element of A. Since a is not an upper bound of A, there is an element s in S such that a ≤ s. But c is an upper bound of S, so s ≤ c.

But c is the least upper bound of S, so c ≤ d. Therefore, c is the least upper bound of A as well. So X has the least upper bound property.Now, to show that [0, 1] is not limit point compact as a subspace of Re, consider the sequence an = 1/n for n ≥ 1. Then, every element of the sequence is in [0, 1], so the sequence is a sequence in [0, 1]. However, the limit of the sequence is 0, which is not in [0, 1].
