The graph represents the heights of two climbers on a climbing wall over a 12-minute time period.A graph titled The Climbing Wall where the horizontal axis shows time (minutes), numbered 1 to 12, and the vertical axis shows height (feet) numbered 2 to 24. The line labeled Brynn's climb begins at 0 feet in 0 minutes, to 15 feet from 5 to 7 minutes, to 0 feet in 10 minutes. The line labeled Abby's climb begins at 4 feet in 0 minutes, to 14 feet from 4 to 6 minutes, to 22 feet in 8 minutes, to 0 feet in 12 minutes.Which statement is true about the climbers’ heights?Brynn was resting at a constant climbing height when Abby’s climbing height was decreasing.Abby’s climbing height was decreasing when Brynn’s climbing height was increasing.The heights of both climbers increased, then decreased, with no rest at a constant height.Both climbers rested on the wall at a constant height for 2 minutes.

Answer:

The Answer is provided in the explanation!

Step-by-step explanation:

The lines are perpendicular because in both of the equations, the x variables are inverses. Meaning, that y=x+7, the x is positive, and y=-x+11, the x is negative. This shows that the slopes of both equations are 1, meaning the graph will have an X shape, provide that lines are perpendicular because they have an inverse of the same slope!

Step-by-step explanation:

Answer:

x = 56

MKL = 56

KML=  63

MLK = 61

Step-by-step explanation:

We know that the sum of the interior angles of a triangle = 180 degrees.

So, x+ (x+7)+ ( x+5) = 180

3x+ 12= 180

3x= 180-12 = 168

168/3 = x

therefore, x= 56 degrees.

So MKL = 56

KML= 56+ 7 = 63

MLK = 56+5 = 61

The distribution A must has a smaller standard deviation. So, option C is correct.

Normal usually refers to the word "normal" in normal distribution.

The normal distribution is somewhat similar where the main observation (mean or its surrounding) occurs frequently and as we go far from mean, its chances decrease.

If we've got a normal distribution, then we can convert it to a standard normal distribution and its values will give us the z score.

If we have

[tex]X \sim N(\mu, \sigma)[/tex]

(X is following a normal distribution with mean and standard deviation )

then it can be converted to a standard normal distribution as

[tex]Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)[/tex]

Normal curve A has a wider distribution than Normal curve B.

The distribution A must has a smaller standard deviation.

Answer:

11 bars

Step-by-step explanation:

Clara bought 11 chocolate bars. Let x be the number of chocolate bars Clara buys.

The cost of each chocolate bar is 63p, so the total cost of x chocolate bars is 63x pence.

After buying the chocolate bars, Clara has 7p left over.

Now we can write the equation:

Total money spent on chocolate bars + Money left over = Total money Clara has initially

63x + 7 = 700 (Since £7 is equivalent to 700p)

Now, let's solve for x:

63x = 700 - 7

63x = 693

x = 693 / 63

x = 11

Answer:

Step-by-step explanation:

the formula for slope is (y2-y1)/(x2-x1)

plug in your coordinates

(12-2)/(3-1)

Answer:

slope (m) = 5

Step-by-step explanation:

(slope)

m = y2-y1 / x2 -x1

Take any of the arbitrary points and plug them into your slope formula.

Let's use (-1,-8) and (1,2) since they are not large numbers (it's easier this way).

-1 (x2) , -8 (y2)

1 (x1) , 2 (y1)

m = -8 - (2) / -1- (1)

= -10/-2

m =5

Answer:

length = 78 m , width = 27 m

Step-by-step explanation:

let w represent width then length l = 3w - 3

the perimeter (P) is calculated as

P = 2l + 2w = 210 , substitute values

2(3w - 3) + 2w = 210 ← distribute parenthesis and simplify left side

6w - 6 + 2w = 210

8w - 6 = 210 ( add 6 to both sides )

8w = 216 ( divide both sides by 8 )

w = 27 and l = 3(27) - 3 = 81 - 3 = 78

Then length = 78 m and width = 27 m

Answer:

x^3 - 3x^2 - 4x + 12

Step-by-step explanation:

Okay, so let's work backwards.

3, -2, 2 are the zeros, so we can use these numbers write the equation in factored form. (For right now, as a placeholder, I'll let y = 0)

(x - 3)(x + 2)(x - 2) = 0

If you want to check this, you can insert each of the zeros into the expression with a constant of the opposite sign.

So now, we can just expand the factored form. (I'll be doing this one equation at a time)

(x - 3)(x + 2) = x^2 + 2x - 3x - 6 = x^2 - x - 6

(x^2 - x - 6)(x - 2) = x^3 - 2x^2 - x^2 + 2x - 6x + 12 = x^3 - 3x^2 - 4x + 12

So,

The equation in standard form is x^3 - 3x^2 - 4x + 12

(Don't take my word for it though, now that I've told you how, feel free to do it on your own)

Answer:

D. pi

Step-by-step explanation:

pi is irrational because you cannot express its value in a simple fraction

:)

Answer:

They are relatively prime.

Step-by-step explanation:

The prime factorization of 46 is 23 * 2, and the prime factorization of 105 is

3 * 7 * 5. Since there are no common factors, they are relatively prime.

There is no common prime number. Then the numbers 46 and 105 will be relatively prime.

When two quantities have just one similar, or if there is no additional value with the same quantity as one, you cannot divide them both and obtain zero as the remainder, two numbers are considered to be relatively prime.

The numbers are 46 and 105.

Then the factor of the number 46 will be

46 = 2 × 23

Then the factor of the number 105 will be

105 = 3 × 5 × 7

There is no common prime number. Then the numbers 46 and 105 will be relatively prime.

Answer:

answer choice A

Step-by-step explanation:

you make two equations.

Jerry's withdrawal involves more money because |-20| is greater than |5|

The vertical bars represent absolute value.

======================================================

Explanation:

Absolute value is the distance a number is from 0. I recommend drawing out a number line. You should see that -20 is further from zero compared to 5.

So this is a visual representation of why Jerry is dealing with more money. You can think of the positive version of each value, which is effectively what absolute value is doing, when comparing the values.

We see that 20 > 5, so Jerry is dealing with more money even though he's losing it rather than gaining it.
