Solve 6x<90. Graph the solution

Answer:

10% to decimal is equal to 0.1.

Therefore 20 x 0.1 = 2

Step-by-step explanation:

Each window is independently probable for having minor defects. The expected number of window frames having minor defects = 2.

Other figures are:

Binomial distributions consists of n independent Bernoulli trials.

Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

Suppose we have random variable X pertaining binomial distribution with parameters n and p, then it is written as

[tex]X \sim B(n,p)[/tex]

The probability that out of n trials, there'd be x successes is given by

[tex]P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]

The expected value and variance of X are:

For the considered case, we can assume that each window is independent of each other for having defects or being perfect.

Each window can be having defects (call it success) or no defects(call it failure).

Then, we can take:

X =  number of windows out of 20 windows being perfect (no defect).

Then we get:

Evaluating each sub parts one by one:

Expect number of defective windows = E(X) = np = 20 × 0.1 = 2

Standard deviation is the positive root of variance.

Standard deviation of number of windows (out of 20 windows of sample) having defects = [tex]\sqrt{Var(X)} = \sqrt{np(1-p)} = \sqrt{2(0.9)} \approx 1.34[/tex]

P(X = 2) = [tex]^{20}C_2(0.1)^2(0.9)^{18} \approx 0.285[/tex]

P(X > 3) = 1 - P(X ≤ 3)

[tex]P(X > 3) = 1 -[ P(X = 0) + P(X = 1) +P(X= 2)+ P(X = 3)]\\\\P(X > 3) = 1- [^{20}C_0(0.1)^0(0.9)^{20} +^{20}C_1(0.1)^1(0.9)^{19} +\\\: \:\: ^{20}C_2(0.1)^2(0.9)^{18} +^{20}C_3(0.1)^3(0.9)^{17} ]\\\\P(X > 3) \approx 1-[ 0.1216 + 0.2702 + 0.2852 + 0.1901]=1-0.8671=0.1329 \\\\P(X > 3) \approx 0.1329[/tex]

For similar triangles ABC and DEF, the value of N=3.

Similarity of a triangle is the ratio of their corresponding sides or angles which are equal.

The given triangles are ABC and DEF,

Side AB = 21, BC = 28, DE = N and EF = 4.

Also, triangle ABC is similar to triangle DEF.

By similar triangle property,

AB/CD = DE/EF

21/28 = N/4

N = 21/7

N = 3

Answer:

CD = EC ⇒ proved down

Step-by-step explanation:

If a point lies on a segment, then it divides the segment into two parts, the sum of their length equals the length of the segment

Example:

If point Z lies on the segment XY, then Z divides XY into segments XZ and ZY, where XY = XZ + ZY

Let us use this fact to solve the question

∵ BD and EF intersected at point C

∴ C divides BD into two segments BC and CD

∴ C divides EF into two segments EC and CF

→ By using the fact above

∴ BD = BC + CD

∴ EF = EC + CF

∵ BD = EF ⇒ given

→ Equate their right sides

∴ BC + CD = EC + CF

∵ BC = CF ⇒ given

→ That means their adding segments are equal

∴ CD = EC ⇒ proved

Answer:

7 hundredths

2 tenths

Step-by-step explanation:

7 is in the hundredths place and there is no zero so then to would be in the tenths place

Let:

Ms. Barton = b

Mr. Weaver = b + 8

Mr. Fitzgerald = 2b - 15

Mr. Lloyd = 1/2b + 30

Find b:

176 = b + b + 8 + 2b - 15 + 1/2b + 30

176 = 9/2b + 23

153 = 9/2b

b=34

Plug in 9 to b:

Ms. Barton = 34 slices (4th place)

Mr. Weaver = 34 + 8 = 42 slices (3rd place)

Mr. Fitzgerald = 2(34) - 15 = 53 slices (1st place)

Mr. Lloyd = 1/2(34) + 30 = 47 slices (2nd place)

Hey there!

Let's find the slope & y-intercept of each equation.

The first one is y=4x-5.

Please remember that

In other words, in slope-intercept form (y=mx+b), m is always the slope and b is the y-intercept.

Therefore,  the slope of the first linear equation is 4, and the y-intercept is -5.

or

m=4, b=-5 (option A)

Same with the other equation:

m=-1, b=2/3 (option C is the right option)

Hope everything is clear.

Answer:

75 degrees and 105 degrees.

Step-by-step explanation:

So this is a transversal. We can use a couple different methods to solve this. We can use many different theorems to solve this problem. So we know that m<2=m<4 because of vertical angles, we also know that m<4=m<6 because of alternate interior angles. We also know that m<6=m<8 because of vertical angles. So we know that m<2=m<4=m<6=<8. In a transversal, there are only two different measurements. And those two different measurements add up to 180 degrees. So since once of the measurements is 75, that means the other measurement has to be 105 degrees. Also, we see that m<4 and m<5 are same side interior angles and according to that theorem, they have to equal up to 180 degrees.

The approximate APR generated when you borrow $1,000 for 5 years at an add-on interest rate of 6%, = $300

Annual percentage rate is defined as the yearly interest generated by a sum that's charged to borrowers.

The formula for APR = p×t×r/100

The principal amount deposited (p)= $1000

Time (t) = 5 years

At the rate (r) = 6%

Therefore APR=

[tex] \frac{p \times t \times r}{100} [/tex]

[tex] \frac{1000 \times 5 \times 6}{100} [/tex]

[tex] \frac{30000}{100} [/tex]

APR = $300

Therefore, the approximate APR = $300
