Answer:

Mean    μ = 5.75

Standard deviation  σ = 2.1041

Step-by-step explanation:

Step(i):-

Given that the size of the sample 'n' = 25

Given proportion p= 23% = 0.23

Let 'X' be the random variable in a binomial distribution

Mean    μ = np = 25 × 0.23 = 5.75

Step(ii):-

Standard deviation

          σ = √npq

         σ = [tex]\sqrt{25 X 0.23 X0.77}[/tex]

        σ = 2.1041

Answer:

w=0.45

Step-by-step explanation:

0.6/1.6=w/1.2

=>w=1.2 x 0.6/1.6

=>w=0.45

Answer:

No, because substituting the given ordered pair doesn't yields two true expressions

Step-by-step explanation:

5x + y = 8

5 + 3 = 8 so thats correct

x + 2y = 5

1 + 6 =7, not 5

so only 1 is correct

Answer:

[tex]y = 4x - 12[/tex]

Step-by-step explanation:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope and b is the y-intercept(value of x when y = 0).

In this question:

Slope 4, which means that [tex]m = 4[/tex].

So

[tex]y = 4x + b[/tex]

Contains point (1,-8).

This means that when [tex]x = 1, y = -8[/tex]. We replace this into the equation to find b. So

[tex]y = 4x + b[/tex]

[tex]-8 = 4(1) + b[/tex]

[tex]b = -12[/tex]

So

[tex]y = 4x - 12[/tex]

Answer: what is the question

Step-by-step explanation:

Answer:

The total purchase price is $370.97.

Step-by-step explanation:

Given;

price of the 35-mm camera, =  $259.99

price of the wide-angle lens = $89.99

TAX rate = 6% = 0.06

The total purchase price = 0.06($259.99 + $89.99) + ($259.99 + $89.99)

The total purchase price = $20.99 + 349.98

The total purchase price = $370.97

Therefore, the total purchase price is $370.97.

Answer:

We conclude that:

f(a) + 5 = a² + 8a - 5

Step-by-step explanation:

Given

The function is given by

f(x) = x²+8x-10

To determine

f(a)+5

In order to determine f(a)+5, first, we need to determine f(a).

Now substitute x = a in the function f(x) = x²+8x-10

f(a) = (a)² + 8(a) - 10

f(a) = a² + 8a - 10

Thus,

f(a) + 5 = (a² + 8a - 10) + 5

f(a) + 5 = a² + 8a - 5

Therefore, we conclude that:

f(a) + 5 = a² + 8a - 5

Answer:

Infinitely many solutions

Step-by-step explanation:

These equations are the same. The only difference being one is written in fractions and the other is in decimals. Since they are the same, they will have infinitely many solutions.

Answer:

The two quantitative elements of process variation are:

a. common cause and special cause.

Step-by-step explanation:

When a process fails to follow the prescribed process pattern, with reduced productivity, higher costs, longer lead times, and late deliveries, a process variation has occurred.  Thus, process variation is a leading cause of quality issues.  There are common cause variation, which is inherent in the system itself, and special cause variation, which is caused by external factors outside of the system.  Process variations can be reduced by reducing the common and special cause variations, among other steps.

Answer:

[tex]P(X=2) = 0.1047[/tex]

Step-by-step explanation:

Represent the probability of hitting the target with H.

So:

[tex]H = \frac{1}{8}[/tex]

Represent the probability of not hitting the target with T.

So:

[tex]T = 1 - H[/tex]

[tex]T =1 - \frac{1}{8}[/tex]

[tex]T =\frac{7}{8}[/tex]

Required

Probability of exactly 2 hits in 5 tries

This probability is a binomial probability and will be calculated using:

[tex]P(X=x) = ^nC_x H^xT^{n-x}[/tex]

In this case:

[tex]x = 2[/tex] i.e 2 hits

[tex]n = 5[/tex] i.e. 5 attempts

So, we have:

[tex]P(X=2) = ^5C_2 H^2T^{5-2}[/tex]

[tex]P(X=2) = ^5C_2 H^2T^3[/tex]

Apply combination formula:

[tex]P(X=2) = \frac{5!}{(5-2)!2!} H^2T^3[/tex]

[tex]P(X=2) = \frac{5!}{3!2!} H^2T^3[/tex]

[tex]P(X=2) = \frac{5*4*3!}{3!2*1} H^2T^3[/tex]

[tex]P(X=2) = \frac{5*4}{2} H^2T^3[/tex]

[tex]P(X=2) = 10* H^2T^3[/tex]

Substitute values for H and T

[tex]P(X=2) = 10* (\frac{1}{8})^2(\frac{7}{8})^3[/tex]

[tex]P(X=2) = 10* \frac{1}{64}*\frac{343}{512}[/tex]

[tex]P(X=2) = \frac{3430}{32768}[/tex]

[tex]P(X=2) = 0.1047[/tex]

Hence, the probability of 2 hits in 5 tries is 0.1047

Answer: Well This is what  24% APR on a credit card is?

If you have a credit card with a 24% APR, that's the rate you're charged over 12 months, which comes out to 2% per month. Since months vary in length, credit cards break down APR even further into a daily periodic rate (DPR). It's the APR divided by 365, which would be 0.065% per day for a card with 24% APR.

The answer is below

Step-by-step explanation:

Trigonometric functions are functions used in right angled triangles to relate an angle in the triangle to the ratio of two side. The most common trigonometric functions are the sine, the cosine, and the tangent.

Some trigonometric identities are:

secθ = 1/ cosθ, cosecθ = 1 / sinθ, tanθ = sinθ / cosθ, cotθ = 1 / tanθ = cosθ / sinθ.

Hence simplifying the question:

[tex]\frac{sin\theta}{cos\theta tan\theta} =\frac{sin\theta}{cos\theta *\frac{sin\theta}{cos\theta} }\\\\=\frac{sin\theta}{sin\theta}\\\\=1[/tex]

Answer:

f(x)=11x+12

Step-by-step explanation:

it shows that the intercept is around halfway between 0 and 20, and the plots are not exactly at the 10s marks, if you look- June is supposed to be 6, but it’s closer to 66. since 6*11=66, i’d say 11x+12 is the answer.
