B and F

the x coordinates shift one to the right, so that's B.

the image flips over the x axis so the y coordinates become negative

Answer:

B and F

Step-by-step explanation:

If you do a horizontal shift to figure ABCDE one unit to the right (B), all points are in line with points HGFJI. Then if you reflect across the X axis (F), both of the figures are in the same location on the graph.

If we consider the toss of four coins as an experiment, how many equally likely outcomes does the sample space have?

Arturiano [62]

There are 16 possible outcomes.

This is found by taking the number of possible outcomes for each toss, 2, and raising it to the 4th power (for 4 tosses):

2⁴ = 2*2*2*2 = 16

The ratios of the measure of the sides of a triangle is 4:10:7. Find the length of each side of the perimeter of the triangle is

dangina [55]

The given ratio of the sides of the triangles is 4:10:7. Let the sides be 4x, 10x and 7x .

And given perimeter is 252 meters .

Perimeter is the sum of all sides. So we get

$4x+10x+7x=252 \\ 21x = 252$

Dividing both sides by 21

$x = 12$

So the sides are

$4*12=48 meters \\ 10*12=120 meters \\ 7*12= 84 meters$

Niu has decorated x cards. He started with 24 stickers, and he used 4 stickers per card.

snow_lady [41]

we are given

total number of stickers =24

stickers per cards =4

We are given

number of cards =x

so, we can use formula

number of cards = ( total number of stickers)/(stickers per cards)

we can plug values

$x=\frac{24}{4}$

$x=6$

so, total number of cards is 6...........Answer

At a small coffee shop, the distribution of the number of seconds it takes for a cashier to process an order is approximately no

iragen [17]

Answer:

The correct option is;

A. 0.17

Step-by-step explanation:

The given information are;

The mean duration it takes a cashier to process an order, μ = 276 seconds

The standard deviation from the mean, σ = 38 seconds

The z-score of the order processing time of x = 240 seconds is given as follows;

$Z=\dfrac{x-\mu }{\sigma }$

Therefore;

$Z=\dfrac{240-276 }{38 } \approx -0.9474$

The probability

P(z = -0.9474) = 0.17361

Therefore, the proportion of orders which are processed in less than 240 is approximately 0.17361 or 0.17 to two places of decimal.

Can someone tell me the surface area and volume for these? I need the steps and formula as well. Please help me.

1st pic

Triangle prism

a triangular end with a base of 27 mm and a height of 23 mm.

the length of each side is 56 mm and the width of each side is 27 mm

SA=bh+(s1+s2+s3)H

SA=(27)(23)+(27+27+27)(56)

SA= 621 + 4536

SA=5157 mm^2

V = ½ blh

V = ½ (27)(23)(56)

V = 17388 mm^3

2nd pic
Cone
SA = πr(r + √(h^2 + r^2) (r = 4, h = 7)
SA = 4π (4 + √(7^2 + 4^2))
SA = 4π (4 + √(49 + 16))
SA = 4π (4 + √65 )
SA = 16π + 4√65

V = 1/3 πr^2h (r = 4, h = 7)
V = 1/3 π (4^2)(7)
V = 112/3 π
V = 37 1/3 π

3rd pic
sphere:

SA = 4 π r^2 as you know r = 14/2 = 7
SA = 4π(7^2) = 4π(49) = 196π m^2

V = 4/3πr^3
V = 4/3π(7^3)
V = 4/3π(343)
V = 1372/3 π
V = 457 1/3 π m^3
