what is the value of A in this equation 4a + 3(a + 1) = 24
a.2
b.3
c.7
d.21

Answers

The the first one the answer should be -4

For the second one the answer should be 3

Answer: Simplifying

4a + 3(a + 1) = 24

Reorder the terms:

4a + 3(1 + a) = 24

4a + (1 * 3 + a * 3) = 24

4a + (3 + 3a) = 24

Reorder the terms:

3 + 4a + 3a = 24

Combine like terms: 4a + 3a = 7a

3 + 7a = 24

Solving

3 + 7a = 24

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 7a = 24 + -3

Combine like terms: 3 + -3 = 0

0 + 7a = 24 + -3

7a = 24 + -3

Combine like terms: 24 + -3 = 21

7a = 21

Divide each side by '7'.

a = 3

Simplifying

a = 3

your friend claims that it is possible to draw a parabola through any two points with different x coordinates. Is your friend correct? explain your answer

Answers

Answer:

yes

Step-by-step explanation:

In general, a (vertical) parabola can be drawn through any 3 non-collinear points having different x-coordinates. For any given pair of points, there are an infinite number of points that are non-collinear with them.

An infinite number of parabolas can be drawn through two points. Your friend is correct.

how many natural numbers N have the property among 1,2,..........,N exactly 30% are divisible by 3?
A. 0
B. 2
C. 6
D. infinite

Answers

Answer:

The answer is B. 2.

Step-by-step explanation:

We know that for N = 1 and N = 2, none of them are divisible by 3.

For N = 3, 33.33% are divisible by 3. For N = 4, 25% (which is already less than 30%), so N = 5 would also be less.

At N = 6, we're back up to 33.33%. N = 7 is already less than 30%.

At N = 9, you guessed it, 33.33%. N = 10 is 30% (3, 6, and 9). So we have one case.

Moving along, at N = 18, 33.33%. N = 20 is again 30% (3, 6, 9, 12, 15, and 18). Two cases now.

Finally, at N = 21, again 33.33%. N = 22 and N = 23 are both greater than 30%. As we continue this, for any N after 20, we will always be greater than 30%.

In an experiment, the probability that even A occurs is 0.2 and the probability that event B occurs is 0.5. If A and B are independent events, which statement is true?

A.
P(A and B) = 0.1

Answers

Answer:

oop

Step-by-step explanation:

The probability of event A and event B will be 0.10. Then the correct option is A.

What is probability?

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

In an experiment, the probability that event A occurs is 0.2 and the probability that event B occurs is 0.5.

If A and B are independent events. Then the probability is given as,

P(A and B) = P(A) x P(B)

P(A and B) = 0.2 x 0.5

P(A and B) = 0.10

The probability of event A and event B will be 0.10. Then the correct option is A.

The total amount of sap y (in ounces) collected from a tree after x weeks is represented by the equation y = 3x + 8. How much more total sap is there after 5 weeks than after 4 weeks?

Answers

x=weeks to get your answer you need to solve y=3(5)+8 which is y=23 and y=3(4)+8 which is y=20. so then you do 23-20 and that equals 3. the answer is 3...i hope this is right!!

3 ounces more sap is there after 5 weeks than after 4 weeks.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, the total amount of sap y (in ounces) collected from a tree after x weeks is represented by the equation y= 3x + 8.

Here, x=4 and x=5 is given

When x=4, we get

y=3(4)+8

= 20

When x=5, we get

y=3(5)+8

= 23

Difference=23-20=3 ounce

Therefore, 3 ounces more sap is there after 5 weeks than after 4 weeks.

Answers

Answer:

83.4% or 83%

Step-by-step explanation:

when trying to find a percent, divide the numerator (# of correct answers) by the denominator (# of total questions possible to get correct)

Which would be 16.67 divided by 20 which equals .8335. Move the decimal point over two placements which would be 83.35. I rounded it up to 83.4. If trying to find a whole number not a decimal it would be 84%. Depending on the grading scale, it would be a B.
