Answer:

-103n = 0

Step-by-step explanation:

Watch my following steps:

8 - 81n - 18 = -10 + 22n

8 - 81n - 22n = -10 + 18

-81n - 22n = 8 - 8

-103n = 0

Answer:

The probability that the lacrosse goalie will make at least 10 saves is 0.558.

Step-by-step explanation:

Let X denote the number of saves the lacrosse goalie will successfully make.

It is provided that the probability of the lacrosse goalie making a successfully save is, p = 0.80.

It is assumed that all save attempts are independent.

Suppose that the lacrosse goalie attempts to make n = 12 saves.

The random variable X follows a binomial distribution with parameters n = 12 and p = 0.80.

Compute the probability that the lacrosse goalie will make at least 10 saves as follows:

[tex]P(X\geq10 )=P(X=10)+P(X=11)+P(X=12)[/tex]

                 [tex]={12\choose 10}(0.80)^{10}(0.20)^{2}+{12\choose 11}(0.80)^{11}(0.20)^{1}+{12\choose 12}(0.80)^{12}(0.20)^{0}\\\\=0.2835+0.2062+0.0687\\\\=0.5584\\\\\approx 0.558[/tex]

Thus, the probability that the lacrosse goalie will make at least 10 saves is 0.558.

Answer:

There are 36 ways in which he can wear combinations with three items of the different color.

Step-by-step explanation:

Hat              Pants           Shirts           Shoes

Answer:

6.8

Step-by-step explanation:

Answer:

1. D and C

2. F = 9/5(k-273) + 32

Step-by-step explanation:

1. We simply want to write the given equation in different forms;

PV = nRT

So P = nRT/V

R = PV/nT

V = nRT/P

n = PV/RT

T = PV/nR

So the correct expressions are;

D, C,

2. we want to make F the subject of the formula, that would be;

C = 5/9(F - 32)

9C = 5(F - 32)

divide both sides by 5

9C/5 = F - 32

F = 9C/5 + 32

But K = C + 273

So C = K - 273

Insert this into the equation, we have

F = 9(K-273)/5 + 32

Answer:

-3(x+4)

Step-by-step explanation:

you just factor out -3

Answer: -3(x+4)

Step-by-step explanation:

Hii, do you need to factor -3x-12? No problem!

Note that -3x and -12 have a -3 in common, so we can factor it out by dividing both -3x and -12 by -3.

x+4 (A negative number divided by a negative number gives us a positive result)

Next, we put parentheses around x+4

(x+4)

Now we put -3 outside these parentheses

-3(x+4)

Voila! There's our solution, cheers!

Answer:

Step-by-step explanation:

Base area =[tex]x^2[/tex]

side area=[tex]h*x[/tex]

Volume=[tex]x^2*h[/tex]=14

Surface area =[tex]4hx+2x^2[/tex]

upon substituting [tex]h=14/x^2[/tex]

surface area = [tex]4*\frac{14}{x^2}*x+2x^2[/tex]

upon differentiating and solving we get  f"([tex]\sqrt[3]{14\\}[/tex]) >0 proves that this point is of minima

hence, dimensions are

[tex]x=\sqrt[3]{14}[/tex] ,h=[tex]\sqrt[3]{14}[/tex]

Answer:

C, 34 inches

Step-by-step explanation:

1. We can see that 30 is the length of one of the sides on the larger parallelogram. The same side has a length of 12 inches on the smaller one. So, we need the difference of these 2 to figure out PQ.

30 - 12 = 18 inches (the difference)

2. Add 18 to 16 (the bottom side on the small parallelogram) to figure out what the bottom side of the large parallelogram would be.

16 + 18 = 34 inches (answer C)

Answer:

Scale factor = [tex] \frac{5}{4} = 1\frac{1}{4} [/tex]

Step-by-step explanation:

The scale factor is how much the right triangle on the right was increased in size or enlarged, since the right triangle is a scaled copy of the one on the left.

The scale factor used = the ratio of any of their corresponding sides

Scale factor = side length of the ∆ on the right ÷ corresponding side length of the ∆ on the left

Scale factor = [tex] \frac{15}{12} [/tex]

Scale factor = [tex] \frac{5}{4} = 1\frac{1}{4} [/tex]

The scale factor expressed as a fraction is 4/5

Since the right triangle on the right is a scaled copy of the right triangle on the left, then the ratio of their similar sides is equal to the scale factor.

This is expressed as:

Taking the ratio of the fractions

[tex]\frac{20}{25} = \frac{4}{5}[/tex]

Similarly for [tex]\frac{12}{15}[/tex]

[tex]\frac{12}{15} =\frac{4}{5}[/tex]

This shows that [tex]\frac{20}{25} = \frac{12}{15} = \frac{4}{5}[/tex]

Hence the scale factor expressed as a fraction is 4/5

Answer:

432 cm[tex]^{3}[/tex]

Step-by-step explanation:

The volume of the box can be determine by using derivative function:

V = (18 - 2x) (18 - 2x) x

dV/dx = 4x^3 + 324 + 144x

equating to zero;

(x - 9) (x - 3) = 0

x = 9 , 3

putting the values in the equation;

V = (18 - 2 [3]) (18 - 2[3]) 3

volume = 432.

Answer:

Shape of sampling distribution of sample mean being approx normal or not depends upon sample size.

Step-by-step explanation:

'The shape of the sampling distribution of the sample mean is approximately normal' might be true or false, depending on sample size.

If the sample size satisfies the condition of being sufficiently large, the shape of sampling distribution of sample mean becomes more bell shaped normally distributed (even more normally distributed than actual population).

Central Limit theorem also states this - Larger the sample size, shape of sampling distribution of sample mean becomes more normally distributed around population mean.

Answer:

34.5744 ≈ 35

Step-by-step explanation:

The formula for Margin of Error

= z × σ/√n

Where

z = z score of the confidence interval = z score of 95% = 1.96

σ = 15 pounds

n = number of samples = ??

Margin of Error = 5

Hence,

5 = 1.96 × 15/√n

Cross Multiply

5 × √n = 1.96 × 15

Divide both sides 5

√n = 1.96 × 15/5

√n = 1.96 × 3

√ n = 5.88

Square both sides

n = 5.88²

n= 34.5744

Approximately the size = 35
