Payment types vary at the grocery store. Here are the proportions of the leading three payment methods: Payment Method Cash Credit Cards Debit Cards Proportion 0.11 0.43 0.21 If a transaction is selected at random, the probability that the customer did not pay with a Debit Card is .

Answers

Answer 1

Answer:

0.79

Step-by-step explanation:

Given the probability distribution :

Payment Methd: Cash Credit Cards Debit Cards Proportion : ____0.11 ____ 0.43 _____0.21

The probability that a customer did not pay with debit card can be obtained as :

If customer did not pay with debit card, then he would have paid with any of the other payment methods

This Can best be obtained using the complement method

P(not debit card) = 1 - P(debit card)

P(debit card) = 0.21

P(not debit card) = 1 - 0.21

P(not debit card) = 0.79

we all know that the angles of a triangle they all add up to 180° meaning when you add them all they must give you 180°

88°+33°+L = 180° ( sum of angle in a ∆)

121° + L = 180°

L = 180° - 121°

L = 59°

Step-by-step explanation:

first you you must add all your angles and all equal to 180°

that you add the like terms

than you transpose 121° to the right hand side

Sam is collecting pennies. On the first day of the month, Sam is given 11 pennies. Each day after that he gets 7 more pennies. Which of the following equations defines how many pennies he has after the nth day?

Answers

Answer:

he would have 74 pennies i think

Step-by-step explanation:

he already has 11 pennies on the first day and each day after he gets 7 more. so putting that into a equation,specifically y=mx+b, the equation would be y=7x+11. since there are 9 days after that,9 would replace the x value. so you would plug 9 in making the new equation y=7×9+11. all u do now is solve, 7×9 is 63,then plus 11 is 74

a solid has volume 2 cubic units and surface area 10 square units. The solid is dilated, and the image has a volume 128 cubic units. What is the surface area of the image?

Answers

Step-by-step explanation:

the answer is 640. Hope this helps

The side length of dilated cubes is 10.08 units. Then the surface area of the dilated cube is 609.6384 square units.

What is dilation?

Dilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.

A solid has a volume of 2 cubic units and a surface area of 10 square units.

The solid is dilated, and the image has a volume of 128 cubic units.

Let the original side length of the cube be a and dilated length of the cube be b.

The value of a will be

[tex]a^3 = 2\\\\a \ = 1.26[/tex]

Then the ratio of their volume will be

[tex]\rm \dfrac{b^3}{a^3} = \dfrac{Dilated \ volume }{Original \ volume }\\\\\\\dfrac{b^3}{a^3} = \dfrac{128}{2}\\\\\\\dfrac{b^3}{a^3} = 64\\\\\\\dfrac{b}{1.26} = 8\\\\\\b \ = 10.08[/tex]

Then the surface area of the dilated cube will be

[tex]\rm Dilated \ surface \ area = 6 *10.08^2\\\\Dilated \ surface \ area = 6*101.6064\\\\Dilated \ surface \ area = 609.6384 \ square \ units[/tex]

A group of campers is going to occupy 6 campsites at a campground. There are 16 campsites from which to choose. In how many ways can the campsites be​ chosen?

Answers

Answer:

The campsites can be chosen in 5,765,760 different ways.

Step-by-step explanation:

Given that a group of campers is going to occupy 6 campsites at a campground, and there are 16 campsites from which to choose, to determine in how many ways the campsites can be chosen, the following calculation must be performed:

16 x 15 x 14 x 13 x 12 x 11 = X

240 x 182 x 132 = X

240 x 24,024 = X

5,765,760 = X

Therefore, the campsites can be chosen in 5,765,760 different ways.

When we expand (2x + 1/2)^6, what is the coefficient on the x^4 term?

Answers

Answer: The coefficient before x^4 is 60

Step-by-step explanation:

Hey! So I am not an expert at this, but you have to use the binomial theorem

I have attached of the Pascals Triangle (one shows the row numbering as well)

Basically in a pascal triangle, you add the two numbers above it to get the next number below

As you can see, the rows start from 0 instead of 1

The 6th row contains the numbers 1, 6, 15, 20, 15, 6, 1 which would be the coefficient terms

NOTE: the exponents always add to 6, the first term starts at 6 and decrease it's exponent by 1 each time (6, 5, 4, 3, 2, 1, 0) and the second term increases it's exponent by 1 each time (0, 1, 2, 3, 4, 5, 6)

Using this information the third term from the sixth row (15) would be where it is x^4 (I have circled it on the second image)

It would be 15 × 2^4 × (1/2)^2 = 60

The reason why it is 2^4 and (1/2)^2 is because the third term has the exponents 4 and 2 (bolded on the NOTE) which means that the first term must be put to the power of 4 and the second term must be put to the 2nd power

Sorry for the lousy explanation. I really hope this makes sense! Let me know if this helped :)

The y values of the table for the function will be -2, -1, 0, 1, and 2.

How to depict the values?

The given function is y = 3✓x. Therefore, for x = -8, y = 3✓-8 = -2. For x = -2, y will be = 3✓-1 = -1.

For x = 0, y = 3✓0 = 0. When x = 1, y = 3✓1 = 1 and lastly when x = 8, y = 3✓8 = 2.

In conclusion, the y values of the table for the function will be -2, -1, 0, 1, and 2.

The length of a rectangle is eight more than double the width. If the perimeter is 130 inches, find the
dimensions.

Answers

Answer:

The length is 46 inches and the width is 19 inches

Step-by-step explanation:

Let w represent the width.

The length of the rectangle can be represented by 2w + 8, since it is eight more than double the width.

Use the perimeter formula, p = 2l + 2w. Plug in 130 as the perimeter and 2w + 8 as l, then solve for w:

p = 2l + 2w

130 = 2(2w + 8) + 2w

130 = 4w + 16 + 2w

130 = 6w + 16

114 = 6w

19 = w

So, the width is 19 inches. Plug in 19 as w into 2w + 8 to find the length:

2w + 8

2(19) + 8

38 + 8

= 46

The length is 46 inches and the width is 19 inches

So for this problem what I did was I divided 210 (the total number of calories) / 10 (calories from the fat). The total came out to be 21 but the answer is incorrect. How would I go about solving this problem?

Answers

For percentages, we divide the part by the whole. In this case, the part is the number of calories from fat and the whole is the total number of calories.

10 / 210 = 0.0476 = 4.76%

Then, we need to round to the nearest tenth.

The answer is 4.8%

The second answer.

Step-by-step explanation:

Tim is correct. Absolute value is just the distance away from 0. In this case, both P and Q are 3/8 away from zero, even though they have opposite signs. In fact, opposites signs of the same number will always have the same absolute value because they are the same distance from 0.

So, it is the second one.

Hope this helps!

Answer:

2nd answer choice:

Tim, because each point is 3/8 unit away from 0

Step-by-step explanation:

The absolute value of a number is how far it is from 0 in the number line, not including direction.

On this number line, point P is -3/8 and point Q is 3/8.

In the number line, count how many units each point is away from 0. You will find that they each have a distance of 3/8 from the number line. Therefore they have the same absolute values.

PS: absolute values are NEVER negative.
