Answer 1

Answer: C

Step-by-step explanation:

Same thing as before(I believe I answered a similar question).

Substitute the values for the variables.

Do that, and you get

(1/2)^2+2/5

= 1/4+2/5

= 5/20+8/20

= 13/20

The answer is C.

Answer:

D it

Step-by-step explanation:

We have two equations, A quadratic and a linear equation.

The domain of a linear equation and quadratic equation is all real numbers but since it dealing with time we must make sure the roots or x-intercepts is positive.

Looking at the quadratic equation, we can use the discramnt formula to see if all roots are positve.

[tex]b {}^{2} - 4ac [/tex]

[tex] { - 6}^{2} - 4(1)(8.75)[/tex]

[tex]36 - 35 = 1[/tex]

The discramnt is greater than zero so there is two distinct real roots. So let check if they are positve

If you graph the equation, it intercepts at two positve roots so it is D

There are 45 calories in 100 g of Coca Cola.
Lionel has 60 g of Twix and 140 g of Coca Cola for a morning snack
Work out the total number of calories in this morning snack.

Answers

Answer:

Amount of calories in 60g of Twix and 140g of Coca cola = 1020 calories

Step-by-step explanation:

Given:

Amount of calories in 100 g of Twix = 510 calories

Amount of calories in 100 g of Coca cola = 45 calories

Find:

Amount of calories in 60g of Twix and 140g of Coca cola

Computation:

Amount of calories in 60g of Twix = 60[510/100]

Amount of calories in 60g of Twix = 306 calories

Amount of calories in 140g of Coca cola = 140[510/100]

Amount of calories in 140g of Coca cola = 714 calories

Amount of calories in 60g of Twix and 140g of Coca cola = 306 + 714

Amount of calories in 60g of Twix and 140g of Coca cola = 1020 calories

Michael is organizing a game of chance for his class. He asks each student to pick a ribbon from a bag and then put it back into the bag. The bag
has 12 yellow ribbons, 7 red ribbons, and 3 blue ribbons. If Jane picks a ribbon, what is the probability that the ribbon will be yellow and what is
the likelihood of this event?
OA. The probability is 1, and the event is certain.
OB. The probability is î and the event is likely.
OC. The probability is it and the event is unlikely.
OD The probability is it, and the event is neither likely nor unlikely.

Answers

Answer:

Step-by-step explanation:

Using the probability concept, it is found that the correct statement regarding the probability of picking a yellow ribbon is given by:

D The probability is of 0.5454 = 54.54%, and the event is neither likely nor unlikely.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, 12 out of 22 ribbons are yellow, hence:

p = 12/22 = 6/11 = 0.5454 = 54.54.

The probability is greater than 0.05 but less than 0.95, hence it is neither likely nor unlikely, which means that option D is correct.

f(-2) = 0

f(1) = 12

f(2) = 5

Step-by-step explanation:

f(-2) will lie in the function [tex] f(x) =x^2 - 4[/tex]

[tex]\therefore f( - 2) = {( - 2)}^{2} - 4 = 4 - 4 = 0 [/tex]

f(1) will lie in the function [tex] f(x) =2x^2 +10[/tex]

[tex]\therefore f(1) = 2 {(1)}^{2} + 10 = 2 + 10 = 12 [/tex]

(8n)(-77)=-77(n*8)

We move all terms to the left:

(8n)(-77)-(-77(n*8))=0

We add all the numbers together, and all the variables

8n(-77)-(-77(+n*8))=0

We multiply parentheses

-616n-(-77(+n*8))=0

We calculate terms in parentheses: -(-77(+n*8)), so:

-77(+n*8)

We multiply parentheses

-616n

Back to the equation:

-(-616n)

We get rid of parentheses

-616n+616n=0

We add all the numbers together, and all the variables

n=0/1

n=0
