Answer:

120 groups

Step-by-step explanation:

Total number of players = 12

Number of superstars = 2

To select a group of 5 players that MUST include the two superstars can be done in how many different ways?

Since the two superstars must always be in the 5 player team

Number of players left to choose = 5 - 2 = 3

Number of players from which selection is to be made = 12 - 2 = 10

Hence, the number of ways of choosing 3 players from 10 ; 10C3

Recall ;

nCr = n! / (n-r)!r!

10C3 = 10! ÷ (10-3)!3!

10C3 = 10! ÷ 7!3!

10C3 = (10*9*8) / (3*2*1)

10C3 = 720 / 6

10C3 = 120 groups

Answer:

x-intercepts: x=3, -5

Step-by-step explanation:

y = x^2 + 2x − 15

y = x^2 + 5x - 3x − 15  ==> 5*(-3)=-15 and 5+(-3) = 5-3=2

y = x^2 + 5x - 3x − 15

y = x(x+5) - 3(x+5)

y = (x-3)(x+5)

x-3=0  ==> x=3

x+5=0 ==> x=-5

x-intercepts: x=3, -5

Answer:

3025

Step-by-step explanation:

let's look at it in this concept.

For a number to be divisible by 11 and 5. it must be a multiple of the LCM of 11 and 5.

LCM of 11 and 5=55

therefore the number is 55x, where x is a positive integer.

it is a said that the number is a perfect square

therefore the square root of 55x must be an integer.

\( \sqrt{55x} = \sqrt{5 \times 11 \times x} \)

the smallest value of x to make 55x a perfect square is....

\(x = 11 \times 5 = 55\)

Therefore the number is.... .

\(55x = 55(55) = 3025\)

As per the mentioned informations, the cash paid for rent during 2014 is calculated to be  $395,000. So, the correct  answer is option (C) i.e. $395,000.

To calculate the cash paid for rent during 2014, we need to use the information given in the problem and apply the following formula:

Cash paid for rent = Rent expense + Prepaid rent at the beginning of the period - Prepaid rent at the end of the period

Substituting the values given in the problem, we get:

Cash paid for rent = $420,000 + $70,000 - $95,000

Cash paid for rent = $395,000

Therefore, it can be concluded that the correct answer is (C) $395,000.

To determine the probability that the fourth person will be the first customer to enter the store, we can use the geometric distribution.

The geometric distribution models the number of trials needed to achieve the first success (entering the store in this case) in a series of independent Bernoulli trials (each potential customer walking by). The probability of success in each trial is given as 0.61.

The probability that the fourth person will be the first customer to enter the store is equal to the probability of three consecutive failures (the first three people not entering the store) followed by a success (the fourth person entering the store).

The probability of failure in each trial is given by (1 - 0.61) = 0.39.

So, the probability that the fourth person will be the first customer to enter the store is calculated as follows:

P(fourth person is the first customer) = P(failure) * P(failure) * P(failure) * P(success)

= 0.39 * 0.39 * 0.39 * 0.61

≈ 0.0602

Therefore, the probability that the fourth person will be the first customer to enter the store is approximately 0.0602, or 6.02%.

Answer:

Total income earn = $422.5

Step-by-step explanation:

Given:

Earning per hour work = $10

Total hour = 40

Commission = 0.5% on sales

Total sales = $4,500

Find:

Total income earn

Computation:

Income from hour work = $10 x 40

Income from hour work = $400

Total commission = 0.5% x sales

Total commission = 0.5% x $4,500

Total commission = $22.5

Total income earn = $400 + $22.5

Total income earn = $422.5

Answer:

y = -10/3x + 5

Step-by-step explanation:

Hi there!

We are given that a line has a slope of -10/3, and a y intercept of 5

We want to write the equation of this same line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

As we are already given the slope and y intercept, we can simply substitute these values into the format for slope-intercept form to find the equation of the line!

Starting with the slope, substitute -10/3 as m in y=mx+b

y = -10/3x + b

Now for the y intercept, substitute 5 as b in the equation

y = -10/3x + 5

Answer:

Step-by-step explanation:96 in the fourth since they are adding the answer itself two times before you get the other like 12 bacteria and then 24 so that means 12 + 12 is 24 and the third one 48 so 24 +24 =48

fourth 48 + 48=96

 fifth 96+96=192

sixth  192+192=384

seventh 384+384=768

Given

y = - 8 /5 x + 2

Comparing the given equation with y = mx + c

slope (m) = - 8/5

Hope it will help :)

Answer:

-8/5

Explanation:

The equation is written in slope-intercept form, aka y = mx + b, where m is the slope and b is the y-intercept.

In slope intercept, the slope is always the number that comes before x.

In the equation y = -8/5x + 2, that number is -8/5.

Hence, the answer is -8/5.

The 95% confidence interval for the difference in means is [-0.98, 10.98], which includes 0.

To calculate the 95% confidence limits on the difference between the means (m₁ - m₂) and the difference between the standard deviations (d), we can use the following formulas:

SE(m₁ - m₂) = √[(s₁²/n₁) + (s₂²/n₂)]

where s₁ and s₂ are the sample standard deviations, n₁ and n₂ are the sample sizes, and SE represents the standard error.

95% confidence interval for (m₁ - m₂) = (x₁ - x₂) ± (t(α/2) * SE(m₁ - m₂))

where x₁ and x₂ are the sample means, t(α/2) is the t-value for the appropriate degrees of freedom and alpha level, and SE(m₁ - m₂) is the standard error.

SE(d) = √[((n₁ - 1)s₁² + (n₂ - 1)s₂²)/(n₁ + n₂ - 2)] * √[1/n₁ + 1/n₂]

where s₁ and s₂ are the sample standard deviations, n₁ and n₂ are the sample sizes, and SE represents the standard error.

95% confidence interval for d = (s₁²/s₂²) * [(n₁ + n₂ - 2)/(n₁ - 1)] * F(α/2)

where F(α/2) is the F-value for the appropriate degrees of freedom and alpha level.

Using the given data, we have:

Expectation good: n₁ = 9, x₁ = 18, s₁ = 4.38

Expectation poor: n₂ = 8, x₂ = 17.125, s₂ = 4.373

SE(m₁ - m₂) = √[(s₁²/n₁) + (s₂²/n₂)] = √[(4.38²/9) + (4.373²/8)] = 1.913

Degrees of freedom = n₁ + n₂ - 2 = 15

t(α/2) = t(0.025) = 2.131

95% confidence interval for (m₁ - m₂) = (18 - 17.125) ± (2.131 * 1.913) = (0.546, 1.429)

SE(d) = √[((n₁ - 1)s₁² + (n₂ - 1)s₂²)/(n₁ + n₂ - 2)] * √[1/n₁ + 1/n₂] = √[((8)(4.373²) + (9)(4.38²))/(17)] * √[1/8 + 1/9] = 1.322

Degrees of freedom numerator = n₁ - 1 = 8

Degrees of freedom denominator = n₂ - 1 = 7

F(α/2) = F(0.025) = 4.256

95% confidence interval for d = (4.38²/4.373²) * [(9 + 8 - 2)/(8)] * 4.256 = (0.754, 3.880)

B. 7 1/2

Answer:

Step-by-step explanation:

firstly we solve 8x=12 we divide both sides by 8 since 8 is the coefficient of x so we are trying to find x that is 8x divided by 8 which is x =12 divided by 8 which is 1.5 which means x=1.5 then we solve the second one 2y+10=22 we collect like terms which means 2y=22-10 as you should know the 10 changes to negative when crossed over to the other side so then 2y=12 is the answer then we divide both sides by the coefficient of y which is 2 so 2y divided by 2 =y 12 divided by 2 = 6 so y=6 then we add both of them together x=1.5+(y=6) so add 1.5 and 6 together answer is 7.5 or 7  1/2
