Answer:

C) English

Step-by-step explanation:

I don't really know how to explain it, so I'll show you instead.

For science, there are 6 of 6 correct answers with a 0.5 chance of answering correctly.

So,

0.5 x 0.5 x 0.5 x 0.5 x 0.5 x 0.5 = 0.016

For English, there are 4 of 4 correct answers with a 0.25 chance of answering correctly.

So,

0.25 x 0.25 x 0.25 x 0.25 = 0.004

They will have to study English (0.004) because it is lower than science (0.016).

The quiz he should study is; English because the probability of getting all questions correct is 0.004 which is lower than for science (0.016).

We are told that for science, there are 6 of 6 correct answers with a 0.5 chance of answering correctly.

Thus;

P(6) = 0.5⁶ = 0.016

We are told that for English, there are 4 of 4 correct answers with a 0.25 chance of answering correctly.

Thus; P(4) = 0.25⁴ = 0.004

Thus, we conclude that they will have to study English because the probability of getting all questions correct is 0.004 which is lower than for science (0.016).

Answer:

25%

Step-by-step explanation:

Initial no of students = 16,000

Final no of students = 20,000

We need to find the percent increase in enrollment.

The increase in no of students = 20,000 - 16,000

= 4000

Percentage = (increase/initial no of students) × 100

[tex]\%=\dfrac{4000}{16000}\times 100\\\\=25\%[/tex]

Hence, the percent increase is 25%.

Answer:

1/2 minutes

Step-by-step explanation:

you add the two fractions together and because they have a common denominator you just add across.

1/8+3/8=4/8

now we simplify

the numerator and denominator can both be divided by 4.

4÷4=1

8÷4=2

Given: Radius , r =21 cm

The angle at the center of the circle, n° =140°

Length of an arc =?

W.K.T Formula, Length of an arc = 2πr( n°÷360°) units

= 2*(22/7)*21*(140°/360°)

= 154/3

= 51.33cm

Answer:

2*(22/7)*21*(140°/360°)

= 154/3

Step-by-step explanation:

Answer:

I think it would be x = -2500

Step-by-step explanation:

You square both sides to get rid of the square root and get -4x = 10000 then divide 10000 by -4 to get -2500

Answer:

y=20x+40

Step-by-step explanation:

slope-intercept form is y=mx+b. In order to place the equation into such format, you first need to move the 20x to the right, meaning you subtract it from both sides. you are left with -y=-20x-40. Since y cannot be negative or have any coefficient other than positive 1, you divide both sides by -1. -20/-1=20,, -40/-1=40,,-1/-1=1. Therefore, you are left with y=20x+40
