c=1 when a randomly chosen card out of a standard deck of 52 playing cards is a heart and c=2 otherwise. draw a histogram showin
Lilit [14]

Answer:

The possible values of c are 1 or 2. There are 13 hearts in a deck of cards and 52-13 = 39 cards that are not. There are a total of 52 cards to choose from, so the possibilities for each value of c are found by dividing the number of results for that value by 52. (Image 1)

Histogram is attached for your reference.

PLEASEEEE HELPPP MEEE <br> 6 and 7 PLEASE
Nitella [24]

Answer:

Question 6

\left(5a+2\right)\left(a+4\right)=\:5a^2+22a+8

Question 7

The width is 2x.

Step-by-step explanation:

                                           Question 6)

Expand

(5a+2)(a+4)

solving to the expand

(5a+2)(a+4)

  • \mathrm{Apply\:FOIL\:method}:\quad \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd

a=5a,\:b=2,\:c=a,\:d=4

so the expression becomes

=5aa+5a\cdot \:4+2a+2\cdot \:4

=5aa+5\cdot \:4a+2a+2\cdot \:4

=5a^2+20a+2a+8

adding similar elements: 20a+2a=22a

=5a^2+22a+8

Hence,

\left(5a+2\right)\left(a+4\right)=\:5a^2+22a+8

                                                  Question 7)

Given

  • A\:=\:8x^2
  • l=4x

Using the formula

width = Area/Length

          =\:\frac{8x^2}{4x}

          =2x                  ∵ \mathrm{Divide\:the\:numbers:}\:\frac{8}{4}=2

Therefore, the width is 2x.
