Answer:

1. x = 8, y =138

2. x = 110

Step-by-step explanation:

First we will need to find the value of x.

Since, I feel like being a kindergartener I'll do it the long way.

(5*2+2)+(6*2)

12+12

That wouldn't work

(5*8+2)=(6*8)

42+48=90

Therefore x = 8

Since we know 42 would be 42 degrees and it is a straight angle for both 5x+2 and y.

We would subtract 180-42=138.

Therefore, y = 138

2 would be simple. All we need to do is add 80+30=110 then subtract it by 180

180-110=70. Since x and the 70 degrees equal 180 degrees.

180-70=110

Therefore, your answer would be x= 110

Ne4ueva [31]

Answer:

C. 0.403

Step-by-step explanation:

Binomial distribution has two parameter n and p. Here, n=15 and p=0.60.

We have to find the probability of 10 or more will show that the hamburger, French fries and a drink were ordered. P(X≥10)=?

The binomial probability distribution function for random variable X is

$P(X=x)=nCxp^{x} q^{n-x}$

where q=1-p=1-0.6=0.4,n=15 and p=0.6.

P(X≥10)=P(X=10)+P(X=11)+P(X=12)+P(X=13)+P(X=14)+P(X=15)

$P(X=10)=15C10(0.6^{10})( 0.4^{5})$ =0.185938

$P(X=11)=15C11(0.6^{11}) (0.4^{4})$ =0.126776

$P(X=12)=15C12(0.6^{12}) (0.4^{3})$ =0.063388

$P(X=13)=15C13(0.6^{13}) (0.4^{2})$ =0.021942

$P(X=14)=15C14(0.6^{14}) (0.4^{1})$ =0.004702

$P(X=15)=15C15(0.6^{15}) (0.4^{0})$ =0.000470

P(X≥10)= 0.185938 +0.126776 +0.063388 +0.021942 +0.004702 +0.000470

P(X≥10)=0.403216

So, the probability of 10 or more will show that the hamburger, French fries and a drink were ordered is 0.403.

Eggs that are contaminated with salmonella can cause food poisoning among consumers. A large egg producer takes an SRS of 200 eg

Paladinen [302]

Answer:

The answer is Option A: "0.2% is a parameter and 11 is a statistic".

Step-by-step explanation:

The main difference between a statistic and a parameter is that a statistic describes a characteristic from a sample and a parameter describes a characteristic of the entire population.

In this case, 11 is the result of the positive salmonella eggs taken out of a sample of 200 eggs. It is a statistic.

Also, we know that of all eggs shipped (the population), 0.2% has salmonella. This 0.2% is a parameter.

The answer is Option A: "0.2% is a parameter and 11 is a statistic".

Which shows one way to determine the factors of x3 + 11x2 – 3x – 33 by grouping?

frozen [14]

Step-by-step explanation:

One way

x3 + 11x2 - 3x - 33

x2(x + 11) - 3(x + 11)

(x + 11) (x2 - 3) are the factors

Y=(x-5)(2x+3) x intercept? HELPPP

jenyasd209 [6]

Answer:

To find the x-intercept, substitute in 00 for yy and solve for xx. To find the y-intercept, substitute in 00 for xx and solve for yy.x-intercept(s): (5,0),(−32,0),(0,0)(5,0),(-32,0),(0,0)y-intercept(s): (0,0)

Hope this helps! :)
