What is the probability of randomly selecting an odd number from the numbers 1-15?​

Answers

Answer 1

Answer:8/15

Step-by-step explanation:

1,3,5,7,9,11,13,15

Answer 2

[tex]{\red{\underline{\underline{\tt{\large{SOLUTION:}}}}}}[/tex]

Numbers from 1-15. The sample space:

[tex]\implies[/tex] S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}

[tex]\implies[/tex] n(S) = 15

Let A be the event that number selected randomly from the numbers 1 to 15.

Event A:

Odd numbers from 1-15. The sample space:

[tex]\implies[/tex] A = {1, 3, 5, 7, 9, 11, 13, 15}

[tex]\implies[/tex] n(A) = 8

Now, as we know that;

[tex] \star \: {\underline{\boxed{\frak{\pmb{\quad Probability \: p(A) = \frac{n(A)}{n(S)} }}}}}[/tex]

Placing values,

[tex]\implies\sf{p(A) = \frac{n(A)}{n(S)} }[/tex]

[tex]\implies\sf{p(A) = \frac{8}{15} } \: \red \star[/tex]

What is the measure of angle 7?
The measure of angle 1 is (3x + 10) and the measure of angle 4 is (4x -
15)
24
68

13

Answers

Answer:

∠7 = 95°

Step-by-step explanation:

∠1 and ∠4 are vertical angles so they are equal.

so:

3x + 10 = 4x - 15

simplify:

x = 25°

∠4 = 4(25) - 15 = 85°

∠8 = ∠4 because they are corresponding angles

∠7 = 180° - 85° = 95° because they are supplementary angles (add together to = 180°)

The average value of a function f over the interval [−2,3] is −6 , and the average value of f over the interval [3,5] is 20. What is the average value of f over the interval [−2,5] ?

Answers

Answer:

The average value of [tex]f[/tex] over the interval [tex][-2,5][/tex] is [tex]\frac{10}{7}[/tex].

Step-by-step explanation:

Let suppose that function [tex]f[/tex] is continuous and integrable in the given intervals, by integral definition of average we have that:

[tex]\frac{1}{3-(-2)} \int\limits^{3}_{-2} {f(x)} \, dx = -6[/tex] (1)

[tex]\frac{1}{5-3} \int\limits^{5}_{3} {f(x)} \, dx = 20[/tex] (2)

By Fundamental Theorems of Calculus we expand both expressions:

[tex]\frac{F(3)-F(-2)}{3-(-2)} = -6[/tex]

[tex]F(3) - F(-2) = -30[/tex] (1b)

[tex]\frac{F(5)-F(3)}{5-3} = 20[/tex]

[tex]F(5) - F(3) = 40[/tex] (2b)

We obtain the average value of [tex]f[/tex] over the interval [tex][-2, 5][/tex] by algebraic handling:

[tex]F(5) - F(3) +[F(3)-F(-2)] = 40 + (-30)[/tex]

[tex]F(5) - F(-2) = 10[/tex]

[tex]\frac{F(5)-F(-2)}{5-(-2)} = \frac{10}{5-(-2)}[/tex]

[tex]\bar f = \frac{10}{7}[/tex]

The average value of [tex]f[/tex] over the interval [tex][-2,5][/tex] is [tex]\frac{10}{7}[/tex].

(2,1)

Step-by-step explanation:

If (0,4) on the line it satisfies the  equations and makes it a true statement. If you plug 0 in for x and 4 in for y you can check and you should get 8=8

You can find the other point in several ways but this is my fav method . You can rearange the equation into y=mx +b  

3x+2y=8

-3x        -3x

2y=-3x+8/Divide everything by 2

y=-3x/2 +4

with this slope is -3x/2 and y is +4

Start at (0,4) move down 3 and right 2 and you get (2,1)

equation, that is, it balances the equation and makes it a true statement.
We can check this by plugging in the numbers.
In the ordered pair given, x =0 and y = 4.
So the equation would look like this:
3(0) + 2(4) = 8
0 + 8 = 8
yes, the equation balances!

Answer:

(a) The width is 40 inches

(b) It will not

Step-by-step explanation:

Given

[tex]D = 50[/tex] -- Diagonal

Solving (a): H = 30 --- (height).

Find the width (W)

To do this, we make use of Pythagoras theorem

[tex]D^2 = H^2 + W^2[/tex]

This gives:

[tex]50^2 = 30^2 + W^2[/tex]

[tex]2500 = 900 + W^2[/tex]

Collect Like Terms

[tex]W^2 = 2500 - 900[/tex]

[tex]W^2 = 1600[/tex]

Take square roots

[tex]W = 40[/tex]

Solving (b): Will it fit into a 30 in wide cabinet?

In (a) above, we calculated the width of the TV to be 40 inches

This implies that, the width is greater than the width of the cabinet.

So, it will not fit in

Step-by-step explanation:

(a) It can be understood that nothing can divide 0

thus denominator cannot be 0 meaning x cannot be -2.

(-2 + 2) = 0

(b) y = sqrt(x-1)

inverse meaning we make x the subject

square both sides

y^2 = x - 1

y^2 + 1 = x

inverse = x^2 + 1

Which of the following models could you use to simulate the
outcome of guessing the correct answer?
F. spinning a spinner with five equal sections
G. flipping a coin five times
H. spinning a spinner with four equal sections
I. rolling a number cube labeled one through six five times

Answers

Answer:

F, spinning a spinner with five equal sections

Step-by-step explanation:

The probability of something is (the ways to acheive the wanted outcome / all possible situations)

For example, the probability of getting heads on a coin flip is (1 possible way to get heads / 2 possible outcomes) = 1/2, or 50/50

Now, onto the problem.

There is only one way to get the answer right, and 5 possible situations. So, the probability of getting the question right would be 1/5.

F) Spinning a spinner with five parts means that you have: 1 way to get the right section, and 5 possible outcomes. So, the probability of getting the right section would be 1/5. So, this answer is correct.

G) Flipping a coin five times: Each time, you have a 1/2 chance of the coin landing on the desired side. So, this would not be an accurate comparison.

H) Spinning a spinner with four equal sections: There is one way to land on the desired section, and 4 possible outcomes. So, the probability of this simulation is 1/4, so this answer is incorrect.

I) Rolling a number cube labeled one through six times: Each time, there is one way to land on the number you want, while there are six possible outcomes. So, the probability of getting your desired number is 1/6, which is incorrect.

The mass of a basket containing 3 balls was 3.64 kilograms. The mass of the same basket and 5 balls is 5.26 kilograms. Find the mass of the empty basket in kilograms. ​

Answers

Answer:

1.21 kilograms

Step-by-step explanation:

Let y represent the mass of the empty basket, and x represent the mass of each ball

Create a system of equations:

3x + y = 3.64

5x + y = 5.26

Solve by elimination by multiplying the top equation by -1

-3x - y = -3.64

5x + y = 5.26

Add them together, then solve for x:

2x = 1.62

x = 0.81

Plug this back into one of the equations and solve for y:

3x + y = 3.64

3(0.81) + y = 3.64

2.43 + y = 3.64

y = 1.21

So, the mass of the empty basket is 1.21 kilograms
