Answer:

2/20

Step-by-step explanation:

x/2 = 1/10

multiply both sides by 2

x = 2/20

Answer:

1.7h - 5.9

Step-by-step explanation:

Combine the like terms -8.9 and 3 to get -5.9. Since it's negative, you subtract.

Answer:

X=14

Step-by-step explanation:

17^2+b^2=19^2

289+b^2=361

361-289=72

The square root pf 72 is ~8.5

subtract 17 from 31 (to get rid of the triangle bases on the bottom).

31-17=14

X=14

Answer:

Range: 28

Mean: 12

Step-by-step explanation:

First line the numbers from small to big: 4, 6, 8, 8, 14, 32

Range is biggest minus smallest number

Mean is just the average: all the numbers' sum divided by the number of numbers

Hope this helps! ;)

Step-by-step explanation:

area of rec= length×width

=10×4

= 40

radius= diameter/2

=4/2 = 2

area of semicircle= πr²/2

=22/7×2×2×1/2

=6.28

=6.3

adding both

we get,

=40+6.3

= 46.3

Answer:

a)

The possible values are 0, 1, 2 and 3.

The probability mass function of X is:

P(X = 0) = 0.125

P(X = 1) = 0.375

P(X = 2) = 0.375

P(X = 3) = 0.125

b)

[tex]P(X \geq 1) = 0.875[/tex], [tex]P(X > 1) = 0.5[/tex]

c) E(X) = 1.5, Var(X) = 0.75

Step-by-step explanation:

For it time the coin is flipped, there are only two possible outcomes. Either it comes up heads, or it comes up tails. Each toss is independent of other tosses. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The variance of the binomial distribution is:

[tex]V(X) = np(1-p)[/tex]

A fair coin is flipped three times.

This means that [tex]n = 3[/tex]

Fair coin means that it is equally as likely to be heads or tails, so [tex]p = \frac{1}{2} = 0.5[/tex]

a) Give both the possible values and probability mass function of X.

The possible values are from 0 to n, so 0, 1, 2 and 3.

The probability mass function is the probability of each outcome. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{3,0}.(0.5)^{0}.(0.5)^{3} = 0.125[/tex]

[tex]P(X = 1) = C_{3,1}.(0.5)^{1}.(0.5)^{2} = 0.375[/tex]

[tex]P(X = 2) = C_{3,2}.(0.5)^{2}.(0.5)^{1} = 0.375[/tex]

[tex]P(X = 3) = C_{3,0}.(0.5)^{3}.(0.5)^{0} = 0.125[/tex]

(b) Find P(X ≥ 1) and P(X > 1).

[tex]P(X \geq 1) = P(X = 1) + P(X = 2) + P(X = 3) = 0.375 + 0.375 + 0.125 = 0.875[/tex]

[tex]P(X > 1) = P(X = 2) + P(X = 3) = 0.375 + 0.125 = 0.5[/tex]

(c) Compute E[X] and Var(X).

[tex]E(X) = np = 3*0.5 = 1.5[/tex]

[tex]Var(X) = np(1-p) = 3*0.5*0.5 = 0.75[/tex]

Answer:

It will take 28 minutes to complete a 7-kilometer race

Step-by-step explanation:

If you can job 3 kilometers in 12 minutes, that means you can jog 1 kilometer in 4 minutes. so if you multiply 7 times 4, you would get 28. So your answer is 28 minutes.

Answer:

x = 29°

Step-by-step explanation:

If line l is parallel to line m, therefore:

(180° - 130°) + 101° + x° = 180° (angles on a straight line)

50° + 101° + x° = 180°

151° + x° = 180°

x = 180° - 151° (substraction property of equality)

x = 29°
