Step-by-step explanation:

Just so you know, the larger a negative number is, the smaller the number's value is.

Answer: 16%

Step-by-step explanation:

168.2 - 145 = 23.2

23.2/145 = 0.16

0.16 as a percent is 16%

The percentage change of the height is A = 16 %

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Christian's height increased by

168.2 - 145 = 23.2 cm

To find the percentage increase, we need to divide the increase by the original height and then multiply by 100:

Percentage increase = (23.2 / 145) x 100%

Percentage increase = 0.16 x 100%

Percentage increase = 16%

Hence , Christian's height increased by 16%

Answer:

5

Step-by-step explanation:

2 + 2+ + 13

2 + 15 + x 2

Combine like terms

2 + 1 5 + 3 +15

ok now when u get that answer u will get a different equation wich is

3 + 15

usually we can solve this by dividing 3 from both sides... 3x/3 = 15/3, getting x=5 as your answer.

Answer: According to the graph, Bobby can get 14 games under Plan B but he can only get 12 games under Plan A.

According to the graph, if Bobby plans to spend $65, then both plans will give him the same number of games because that is the point where the two plans are the same.

Answer:

[tex]m = n[/tex] --> Corresponding angle

[tex]x = y[/tex] --> Vertically opposite

Step-by-step explanation:

Given

The attachment

Required

State the reason for the given statements

m = n

m and n are corresponding angles.

So:

[tex]m = n[/tex]

x = y

x and y are vertically opposite angles

So:

[tex]x = y[/tex]

[tex]y + n = x + m[/tex]

In (b)

[tex]x = y[/tex]

Add m to both sides

[tex]x + m = y +m[/tex]

In (a) [tex]m = n[/tex]

So, substitute n for m on the left hand side

[tex]x + n = y + m[/tex]

Answer:

45.

Step-by-step explanation:

Since Hideki is draining a 45 gallon aquarium at a rate of 15 gallons per minute, to determine what is the initial value of the linear function that represents the situation, the following calculation must be performed:

45 (starting number) - 15(number of gallons per minute) X(minutes) = Y

Therefore, the equation would be 45 - 15X = Y, with which the initial value of the linear function that represents the situation is 45.

Answer:

AC = 8

Step-by-step explanation:

AC = 4x + 8

BE = x + 2

x + 2 = x + 2

2x = 2 - 2

2x = 0

2x\2 = 0/2

x = 0

AC = 4x + 8

AC = 4(0) + 8

AC = 0 + 8

AC = 8

When the AC= 4x + 8 and BE = x + 2, so the length of diagonal AC is to be considered as the 8.

Since

AC = 4x + 8

BE = x + 2

Now

x + 2 = x + 2

2x = 2 - 2

2x = 0

x = 0

Now

AC = 4x + 8

AC = 4(0) + 8

AC = 0 + 8

AC = 8

hence, the length of diagonal AC is to be considered as the 8.

Step-by-step explanation:

Answer:

0.784 = 78.4% probability that there will be at least one failed graft in the next three done

Step-by-step explanation:

To solve this question, we need to understand the binomial probability distribution and conditional probability.

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.

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: No failed grafts in the first seven

Event B: At least one fail in the next three.

Intersection of events A and B:

Since the probability of a graft failling is independent of other grafts, we have that:

[tex]P(A \cap B) = P(A)*P(B)[/tex]

So

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{P(A)*P(B)}{P(A)} = P(B)[/tex]

So we just have to find the probability of one fail in three trials.

Three trials means that [tex]n = 3[/tex].

The probability is

[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]

In which

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

[tex]P(X = 0) = C_{3,0}.(0.4)^{0}.(0.6)^{3} = 0.216[/tex]

Then

[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.216 = 0.784[/tex]

0.784 = 78.4% probability that there will be at least one failed graft in the next three done
