Answer:

I am expected to win $150

Step-by-step explanation:

We need to calculate the probability of drawing 2 black cards with replacement

There are 26 black cards in a deck of cards

The probability of drawing a black card is thus 26/52 = 1/2

So the probability of drawing two black cards in succession with replacement will be 1/2 * 1/2 = 1/4

So the probability of not drawing the two in succession will be 1 - 1/4 = 3/4

so out of twenty trials the number of times the drawing will occur will be 1/4 * 20 = 5 times

The number of times it will not occur will be 20-5 = 15 times

The amount my friend will win will be 5 * 30 = 150

The amount I will win will be 20 * 15 = 300

The amount I expect to win in the deal will be 300-150 = $150

Answer:

The correct answer is:

Sydney should choose the median after dropping one test score.

Step-by-step explanation:

when scores are not dropped:

List of scores = 68%, 84%, 94%, 100%

Mean = (68 + 84 + 94 + 100) ÷ 4 = 86.5%

Median = 68  84  94  100

Median = (84 + 94) ÷ 2 = 89%

Although there are no outliers because Sydney was given the option to drop a test score, dropping the lowest score will increase his overall chances of making a higher score. Therefore, 68% will be dropped.

List of scores when the lowest score is dropped  = 94%, 84%, 100%

Mean: (84 + 94 + 100) ÷ 3 = 92.7%

Median: 84, 94, 100

Median = 94% (middle term)

From  the four possible scores, the highest score is 94%, and it is gotten by finding the median after dropping a score

Answer:

c ;)

Step-by-step explanation:

Answer: 48s+12p-18 this is the correct answer i just took the test

The expression that represents the total cost can be written as -

y = as + pb - 18.

Given is that at the ski shack, customers can rent, skis, snowboards, boots, and poles by the day. Mrs. Alvarez is renting skis and poles.

Assuming the cost to rent skis for 1 day is $a and the cost of renting the poles is $b. Then we can write the expression that represents the total cost as -

y = as + pb - 18

Therefore, the expression that represents the total cost can be written as - y = as + pb - 18.

Step-by-step explanation:

1/6*1/6

Answer:5:6

Step-by-step explanation:

Step-by-step explanation:

diameter of semicircle is 6 so radius is 6/2=3

so perimeter of the circle would be

p=2πr

p=2π*3=6π=18.8

But we have a semicircle so perimeter will be

P=p/2=18.8/2=9.4

The perimeter of the figure now would be

Perimeter=9+8+8+9.4=25+9.4=34 approximately.

The perimeter of the figure below, composed of an isosceles trapezoid and one semicircle is 34.4 units.

The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.

From the given figure, equal sides of an isosceles trapezoid is 8 units, and parallel sides are 9 units and 6 units.

Radius of semicircle is 6/2 = 3 units

Now, perimeter = 9+8+8+Circumfrence of a semicircle

= 25+πr

= 25+3.14×3

= 25+9.42

= 34.4

Therefore, the perimeter is 34.4 units.

Answer:

Step-by-step explanation:

From the information being provided;

We learnt that Becky pays simple interest at an annual interest rate of 8.8% which is calculated quarterly.

i.e. [tex]\dfrac{8.8\%}{4}= 2.2\%[/tex]

Since the first payment of $27,000 happened in the first three months, therefore, Becky will be able to have the money in the bank for 3 quarters prior to the lump-sum payment gets started.

Thus, the estimate of the amount Becky would earn as interest during this period of time is as follows:

[tex]I =\dfrac{PRT}{100}[/tex]

[tex]I =\dfrac{27000\times 2.2 \times 3}{100}[/tex]

[tex]I =\dfrac{178200}{100}[/tex]

I = $1,782

Answer:

a= c+16

a-c= 16

Step-by-step explanation:

a = b + 12

b = c + 4

adding both eq.s, we get:

a+b = b+c+12+4

a+b = b+c+16

a = c+16

a-c = 16

Complete Question:

Jamie used the distributive property to find the product of s(t) and h(t). His work was marked incorrect. Identify Jamie's mistake. What advice would you give Jamie to avoid this mistake in the future?

s(t)•h(t)= (3x-4)(2x-8)

= 6x² - 24x -8x - 32

= 6x² - 32x - 32

Answer:

Jamie made a mistake in his second line (6x² - 24x -8x - 32), by wrongly multiplying the operation signs. The last term should be +32, not -32.

Advice: Jamie should take note of the rule that applies when multiplying signs.

Step-by-step Explanation::

To find out where exactly Jamie made mistake, let's find the product of the given functions, step by step:

s(t)•h(t)= (3x-4)(2x-8)

Using distributive property, do the following:

[tex] 3x(2x - 8) -4(2x - 8) [/tex]

[tex] 3x*2x -3x*8 -4*2x -4*-8 [/tex]

[tex] 6x^2 - 24x - 8x + 32 [/tex] (this is where Jamie made mistake. -4 * -8 = +32. NOT -32.)

Add like terms

[tex] 6x^2 - 32x + 32 [/tex]

Jamie made a mistake in multiplying negative × negative. The last term in "6x² - 24x -8x - 32", should be +32. Negative × negative = +.

Therefore, it is advisable for Jamie to always take note of the rule that applies when multiplying signs.

Answer:

2x+y=−7

Step-by-step explanation:

Both these angles are vertically opposite angles due to which their angle measures will be equal .

Which means :-

[tex]12x + 9 =13 x + 1[/tex]

[tex]9 = 13x + 1 - 12x[/tex]

[tex]9 = 1x + 1[/tex]

[tex]1x + 1 = 9[/tex]

[tex]x + 1 = 9[/tex]

[tex]x = 9 - 1[/tex]

[tex]x = 8[/tex]

Which means :-

= 12 × 8 + 9

= 96 + 9

= 105°

= 13 × 8 + 1

= 104 + 1

= 105°

Therefore :-

angle 12x + 9 = 105° ( x = 8)

angle 13x + 1 = 105° ( x = 8 )

Answer:

1) x = -10

2) x = 39

3) x = 11

Step-by-step explanation:

1) x + 3 = -7

=> x= -7-3

=> x= -10

2) 2/3x + 1 = 27

=> 2/3x = 27 - 1

=> 2x =26 * 3 (26 multiply by 3)

=> x = 78/2

=> x =39

3) 4x-7 = 2 (x+3) +9

=> 4x-7 = 2x+6+9

=> 4x-2x =7+6+9

=> 2x = 22

=> x =22/2

=> x = 11
