Answer:

b.

$7.68

Step-by-step explanation:

23.99 * 15%

23.99 * .15 = 3.60 off

23.99-3.60 =20.39 new price

now to use the coupon

20.39 * 20%

20.39*.20= 4.08 off

20.39 - 4.08 =16.31


23.99-16.31 = 7.68

He saved 7.68

Answer:

7 yd

Step-by-step explanation:

You are finding the perimeter. Your answer should include yd (yd² is for area, yd³ is for 3d images).

Note that the two lines segments (? & 9) is parallel to the other line segment (16). Find the ?:

? + 9 = 16

? + 9 (-9) = 16 (-9)

? = 16 - 9

? = 7

What is the value of x?
antoniya [11.8K]
Since the figure is a rhombus, the diagonals cut each other at right-angles and bisect each other, namely cut their vertices in equal halves.

what the dickens does all that mean?  well, the angles at vertex C and vertex A are all twins, and therefore, ∡BCA = x, therefore

\bf (3x-26)+(x)+(90)=180\implies 4x+64=180\implies 4x=116
\\\\\\
x=\cfrac{116}{4}\implies x=29

20% of the patron's order the chef's special. The probability that 2 out of the next ten customers will order the chef's special
kotegsom [21]

Answer:

P(x =2) = 0.3020

Step-by-step explanation:

Given

p =20\% = 0.20

n = 10

Required

P(x = 2)

This question is an illustration of binomial distribution where:

P(X = x) = ^nC_x * p^x * (1 - p)^{n-x

So, we have:

P(x =2) = ^{10}C_2 * 0.20^2 * (1 - 0.20)^{10-2}

P(x =2) = ^{10}C_2 * 0.20^2 * 0.80^8

This gives

P(x =2) = \frac{10!}{(10 - 2)!2!} * 0.20^2 * 0.80^8

P(x =2) = \frac{10!}{8!2!} * 0.20^2 * 0.80^8

Expand

P(x =2) = \frac{10*9*8!}{8!2*1} * 0.20^2 * 0.80^8

P(x =2) = \frac{10*9}{2} * 0.20^2 * 0.80^8

P(x =2) = 45 * 0.20^2 * 0.80^8

P(x =2) = 0.3020
