Gabriel determined that his total cost would be represented by 2.5x + 2y – 2. His sister states that the expression should be x + x + 0.5x + y + y – 2. Who is correct? Explain.

Answer:

For each of the shoes, you would want to find out how much money they are saving and subtracting it from the total

Step-by-step explanation:

Store A:

54.99*20%=11.00

54.99-11.00=$43.99

Store B:

59.99*30%=18.00

59.99-16.50=$41.99

The required store that has lowest price of item is store B. Option B is correct.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

here,
In Store A, a pair of shoes that regularly sell for $54.99 is on sale at 20% off.

In Store B, the same pair of shoes regularly sells for $59.99 and is on sale at 30% off.

Cost of shoe in store A = 54.99 (1 - 0.2) = $43.99
Cost of shoe in store B = $59.99 (1 - 0.2) = $43.99

Thus, the required store that has lowest price of item is store B. Option B is correct.

The answer is 8 so its a direct proportion

I think...

The constant of Proportionality is 8.

If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.

Given:

Total Baseball Caps= 30

Total amount of Cap= $240

let the number of caps sold be c.

Then, the equation is

30 c= 240

and, c= 240/30

c= 8

Hence, the constant of Proportionality is 8.

Answer:

this probability is 3/4.

Step-by-step explanation:

The spinner has the numbers 2, 3, 4, and 5. Since the question asks for the probability of spinning a number less than 5, we need to consider the numbers 2, 3, and 4.

Out of the four numbers on the spinner, three of them (2, 3, and 4) are less than 5.

Therefore, the probability of spinning a number less than 5 is 3 out of 4.

Answer:

You spin the spinner once.

The answer is B because the others answer choice are incorrect.

Answer:

For the top: Angles E,F,B and D are all Supplementary to angle M.

Each of them has a measure of 135°

For the bottom, angles J,H,P and R are all Supplementary to angle M. They all have measures of 105°

Step-by-step explanation:

The directions say "identify an angle" so you can select any one of the angles listed.

Supplementary angles add to 180° so to find the measure, Subtract the given measure from 180.

180-45=135 180-75=105

Answer:So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.

So basically the units are counting up by 5.

The x axis is age in years and y axis is the number of US states named in 60 seconds.

Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.

(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)

Im no expert but you would need information on the length and width of the rectangular garden and walkway. To figure this out you would need the information on the width of the walkway and length and width of the rectangle.

Let's pretend a rectangle has a width of 4 and length of 6. I would do 4x6. Then for the walkway lets pretend the width is 3. Since the we know the length of the rectangle is 6 and the width 4, I would do 2(6x3)+2(4x3).

Answer: Range and mean = 8 of both

variance of Set X= 4.7

variance of Set Y= 4.6

Step-by-step explanation:

Two sets of data, set X and set Y are given

a.) Range is the difference of the highest value and the lowest value,

Therefore, Range of set X = 12-4=8

Range of set Y = 12-4=8

Now, Mean of a given data set is the average of all the terms present in the given data set

Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8

Mean of set Y= (4+5+7+32+20+12)/10= 8

Therefore, both the data sets has same range and mean.

b.) Standard deviation tells about the variability of the date and is given by,

S.D= σ = √∑ ( X − μ )^2/n

S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7

S.D of set Y= √(16+9+1+0+4+16)/10= √4.6

Variance is the square of S.D, that is, σ^2

Therefore, variance of set X=4.6

variance of set Y= 4.7

c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Answer:

Hence, 70 people out of 100 who had attained the previous year

Step-by-step explanation:

If this is completely proportional, you'd make the formula

\( \frac{420}{600} = \frac{x}{100} \)

Cross multiply

\(42000 = 600x\)

Then we just divide by 600

\(x = 70\)

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

\(\frac{16}{27}\)

Step-by-step explanation:

From the table, we notice that the total number of students is:

\(3+10+8+6=27\)

Then, along the second column of the table, we notice that the number of students who do not have a brother is:

\(10+6=16\)

So, the probability that a randomly chosen student does not have a brother is:

\(\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}\)
