Please help. I’m confused and dumb-

Answer:

60

Step-by-step explanation:

so 4 of BC will make a AB, so AC =5 of BC =75

therefore BC=75/5=15

If BC=15 and AB=4*BC=4*15=60

It's -46, because if you add -6 and -46 you get -52

Answer:

30 degrees

Step-by-step explanation:

<AIN is equal to <FIL because they are vertically opposite.

Step-by-step explanation:

1 is the starting point since it is on the the axis.

then you would use the rise over run method to get the fraction. it rises by two and runs by 1 which would get you 2/1. so the answer should be y=1+2/1

(it is an addition sign since it is a positive slope)

Answer:

The actual relative abundance will be "7.59".

Step-by-step explanation:

The predicted relative abundance for 3 inches rainfall will be:

= [tex]6.7 - (0.12\times 3)[/tex]

= [tex]6.34[/tex]

The residual will be:

= [tex]actual - predicted \ relative \ abundance[/tex]

= [tex]1.25[/tex]

Now,

The actual relative abundance will be:

= [tex]1.25 + predicted \ relative \ abundance[/tex]

= [tex]1.25 + 6.34[/tex]

= [tex]7.59[/tex]

Remember that perhaps the residual positive value means that even the calculation underestimates the relative abundance. The real relative abundance, however, is 7.59.

Answer: -15

Step-by-step explanation:

The average rate of change for the interval from x = 7 to x = 8 is -15. The correct option is B.

A quadratic polynomial in mathematics is a polynomial of degree two in one or more variables. The polynomial function defined by a quadratic polynomial is known as a quadratic function.

Since the quadratic function has a vertex at (0,3), the equation for the function can be written in vertex form as:

y = a(x - 0)^2 + 3

Where "a" is a constant that determines the shape of the parabola. To find the value of "a", we can use one of the other points on the parabola. Let's use the point (1, 2):

2 = a(1 - 0)^2 + 3

Simplifying this equation, we get:

a = -1

So the equation for the quadratic function is:

y = -x^2 + 3

Now we can use this equation to find the average rate of change between x = 7 and x = 8. The value of the function at x = 7 is:

y = -7^2 + 3 = -46

The value of the function at x = 8 is:

y = -8^2 + 3 = -61

The average rate of change between x = 7 and x = 8 is:

(y2 - y1) / (x2 - x1) = (-61 - (-46)) / (8 - 7) = -15

Therefore, the average rate of change for the interval from x = 7 to x = 8 is -15.

In a normal distribution, 95% of the data falls within two standard deviations.

What is a normal distribution?

The most typical distribution function for independent, randomly produced data is the normal distribution, commonly known as the Gaussian distribution. Every statistical report uses this well-known bell-shaped curve, from survey analysis and quality control to resource allocation.

Here,

We have to determine in a normal distribution, 95% of the data fall within how many standard deviations of the mean.

We concluded that 95% of the data points will fall within two standard deviations of the mean. 99.7% of the data points will fall within three standard deviations of the mean.

Hence, In a normal distribution, 95% of the data falls within two standard deviations.

John attempted 500 passes.

Step-by-step explanation:

350 / x = 70%

350 = 0.7x

x = 500

Answer:

d = 25

Step-by-step explanation:

d = sqrt( (y2 - y1)^2 + (x2 - x1)^2  )

d = sqrt( (7  - 22)^2 + (2 - (-18) )^2  )

d = sqrt (  (- 15)^2 + 20^2 )

d = sqrt ( (225) + (400) )

d = sqrt (625)

d = 25

By direct calculation, we will see that Jessie can go to 7 rides in the county fair.

So we know that the cost of admission is $5.00 and each ride costs $2.00.

So if you go to the county fair and go to x rides, the cost is:

c(x) = $2.00*x + $5.00

And you have $19, then by solving:

c(x) = $19

We can find the number of rides at which Jessie can go.

$19 = $2.00*x + $5.00

$19 - $5 = $2*x

$14 = $2*x

$14/$2 = x = 7

Jessie can go to 7 rides.

Answer:

X = -4 1/3 or -4.333 or -13/3

Step-by-step explanation:

2(x+5) = 5x+23

2x + 10 = 5x+23

2x-2x + 10 = 5x-2x +23

10 = 3x + 23

10-23 = 3x + 23-23

-13 = 3x

-13/3 = 3x/3
