Round 21.253 to the nearest hundred.​

Answers

Answer 1

I don't know if you meant to say hundredth but in this case you said hundred and I can't just make assumptions.

The answer is

- - - - -

0

Like literally, I am not stealing your points but you said to the nearest hundred. So in this case, it'd be 0.

Answer 2
21.253 to the nearest hundredth would be
21.25!

The hundredths place is the second number to the right of the decimal, you will look at the thousandths place (3rd number to the right) and if it is less than 5 you will keep the hundredths the same, if it is above 5 you will round the number up.

In this case, your thousandths spot is less then 5, therefore the answer is 21.25 !!!

Select the correct answer. Graph the given function and choose the key features that apply to its graph. y = x2 − 2x − 4

Answers

Answer:

Step-by-step explanation:

y = x^2 - 2x - 4

Convert to vertex form:

y = (x - 1)^2 - 1 - 4

y = (x - 1)^2 - 5

From this we conclude that there is a minimum vertex at (1, -5). It is a minimum because the coefficient of x^2 is positive.

It looks like a letter U  and its symmetrical about the line x = 1.

You can plot 3 more points at say, where x = -2  ( and y = (-2)^2 - 2(-2) - 4)

and x = 4 ( y = 4^2 - 2(4) - 4 ) . Also where x = 0 and y = -4.

then draw the graph through these 3 points and the vertex.

Is the line a good fit for the data points plotted in the scatter plot below?

It would be A. Because the line is close to the points which makes it a good fit!

If x = 7 units, y = 2 units, and h = 9 units, find the area of the trapezoid shown above using decomposition.
A.
81 square units
B.
99 square units
C.
63 square units
D.
72 square units

Answers

Answer:

A) 81 sq units

Step-by-step explanation:

Area of a trapezoid = one-half of height multiplied by the sum of the bases (the bases are the parallel sides)

the problem gives us all the values we need:

height = 9

smaller base is 'x' which is 7

larger bases is 2y+x which is 2(2)+7 = 11

A = 1/2·(9)(7+11)

= 1/2·9·18

= 9·9 which is 81 sq units

3. Is XY Tangent to circle Z?

Answers

Answer:

XY is a tangent

Step-by-step explanation:

Given

[tex]XY = 12[/tex]

[tex]WY = 20[/tex]

[tex]WZ = 8[/tex]

Required

Is XY a tangent?

XY is a tangent if:

[tex]WY^2 = XY^2 + WX^2[/tex]

Because XY should make a right angle at point X with the circle

Where

[tex]WX = 2 * WZ[/tex]

So, we have:

[tex]WY^2 = XY^2 + WX^2[/tex]

[tex]WY^2 = XY^2 + (2*WZ)^2[/tex]

[tex]WY^2 = XY^2 + (2WZ)^2[/tex]

[tex]WY^2 = XY^2 + 4WZ^2[/tex]

This gives:

[tex]20^2 = 12^2 + 4*8^2[/tex]

[tex]400 = 144 + 256[/tex]

[tex]400 = 400[/tex]

Yes, XY is a tangent

The times that a cashier spends processing individual customers' orders are independent random variables with mean 3.5 minutes and standard deviation 3 minutes. Find the number of customers n such that the probability that the orders of all n customers can be processed in less than 2 hours, is approximately 0.1. (Round your answer to the nearest integer.)

Answers

Answer:

26 customers

Step-by-step explanation:

First:  determine the z score from standard normal probability table with an indicative area of 0.1

Z-score from probability table  = - 1.28

mean   = 3.5 minutes

std  = 3 minutes

next determine the Z-score based on the information given in the question

Z = ( std -  mean )  / processing time

  = ( 3 - 3.5 ) / 2 = -0.25

Finally determine the number of customers

N = [tex](\frac{-1.28}{-0.25} )^2[/tex]  = 1.6384 / 0.0625 = 26.21 ≈ 26 customers
