Maureen owns three bagel shops. Each shop sells 500 bagels per day. Maureen asks her store managers to use a random sample to see how many whole what bagels

Answers

Answer 1

Answer:

In complete questions, the completed question is in ask details

Step-by-step explanation:

Maureen has 3shops

Each sells 500bagels per day

shop A

Total bagels sample is 50 and 10 whole wheat bagels

Shop B

Total bagels sample is 100 and 23 Whole-wheat bagels

Shop C:

Total bagels sample is 25 and 7 Whole-wheat bagels.

It is noticed that the simple space of shop B is more than shop A, notice that shop B sample space is small and it can not give a reasonable valid inference.

Then, Both shop A and shop B sample space is large enough to give a reasonable valid inference

What is 0.32 written as a fraction in simplest form?

Answers

0.32 in fraction form is 32/100. then to make it simplest form, divide by a common factor. 32/2 = 16 and 100/2 = 50, which gives you 16/50, however this can be simplified more. divide by 2 again and you have 8/25, which cannot be simplified any further. another way to have found this answer would be to find the greatest common factor as the first step, which would be 4; 32/4=8 and 100/4=25

Okay the last number behind the decimal is in the hundredths place put 32 over 100. 32/100. Now find a number they can both be divided equally by. The highest number they can both be divided by is 4. 32÷4=8 and 100÷4=25 now put 8 over 25 and you have your answer. ANSWER: 32/100=8/25

Find two consecutive odd integers whose sum is 176

Answers

consecutive odd integers aer 2 apart

they are n and n+2
the sum is add
n+n+2=176
2n+2=176
minus 2 both sides
2n=174
divide both sides by 2
n=87
n+2=89
the numbers are 87 and 89

Triangle XYZ has vertices X(1, 3), Y(0, 0), and Z(–1, 2). The image of triangle XYZ after a rotation has verticesX'(–3, 1), Y'(0, 0), and Z'(–2, –1). Which rule describes the transformation?

Answers

Answer:

Rotation about 90° counter clockwise (x , y) →→ ( -y, x ).

Step-by-step explanation:

Given : Triangle XYZ has vertices X(1, 3), Y(0, 0), and Z(–1, 2). The image of triangle XYZ after a rotation has vertices X'(–3, 1), Y'(0, 0), and Z'(–2, –1).

To find : Which rule describes the transformation.

Solution : We have given

vertices X(1, 3) →→ X'(–3, 1)

Y(0, 0) →→ Y'(0, 0),

Z(–1, 2) →→ Z'(–2, –1).

Here , we can see in each coordinates value of y become -x and x become y.

(x , y) →→ ( -y, x ) this the rule of rotation about 90° counter clockwise.

Therefore, rotation about 90° counter clockwise (x , y) →→ ( -y, x ).

the rule is (x - 3, y - 3).

Four hundred vouchers were sold for a carwash. Vouchers to wash trucks were $4, while vouchers to wash compact cars were $3. If the total sales were $1350, how many of each type of voucher were sold?

Answers

Answer:

150 vouchers to wash trucks were sold

250 vouchers to wash compact cars were sold

Step-by-step explanation:

Here, we are interested in calculating the number of each type of vouchers sold.

Let the number of vouchers to wash trucks be x while the number of vouchers to wash compact trucks be y.

Firstly, we know that both sums up to be 400.

Mathematically;

x + y = 400 •••••••••(i)

Secondly,

since a voucher to wash trucks sell $4, and we sold a total of x, the amount generated from selling is 4 * x = $4x

Same way for the vouchers to wash compact cars, we have a total of $3 * y = $3y

The sum of both gives $1350, which is the total sales.

Mathematically;

4x + 3y = 1350 ••••••(ii)

So we have two equations to solve simultaneously;

x + y = 400

4x + 3y = 1350

Multiply equation i by 4 , we have;

4x + 4y = 1600

4x + 3y = 1350

Subtract equation ii from i, we have 4y-3y = 1600-1350

y = 250

From equation 1, we know that

x + y = 400

This means that;

x = 400 -y

x = 400 -250

x = 150
