in the figure, AC=20cm CD=22cm and AE=16cm find the length of BD.
Answers
Answer:
17.6 cm
Step-by-step explanation:
Area of triangle equals to half of the base times height, i.e. A = 1/2 × b × h.
1/2 x 22 x 16 = 1/2 x 20 x BD
BD = (1/2 x 22 x 16) / (1/2 x 20)

the probability of randomly selecting a four-person committee consisting entirely of canadians from a pool of 11 americans and 18 canadian
Answers
Answer:
[tex]Probability =0.1744[/tex]
Step-by-step explanation:
Given
Total
[tex]American = 11[/tex]
[tex]Canadian = 18[/tex]
Selection
[tex]American = 0[/tex]
[tex]Canadian = 4[/tex]
Required
Determine the probability of selecting a 4 committee member that are Canadian.
First, we calculate total possible selection.
[tex]Total = American + Canadian[/tex]
[tex]Total = 11 + 18[/tex]
[tex]Total = 27[/tex]
Number of ways to select 4 from 27 is:
[tex]^{27}C_4 = \frac{27!}{(27-4)!4!}[/tex]
[tex]^{27}C_4 = \frac{27!}{23!4!}[/tex]
[tex]^{27}C_4 = \frac{27*26*25*24*23!}{23!4!}[/tex]
[tex]^{27}C_4 = \frac{27*26*25*24}{4!}[/tex]
[tex]^{27}C_4 = \frac{27*26*25*24}{4*3*2*1}[/tex]
[tex]^{27}C_4 = \frac{421200}{24}[/tex]
[tex]^{27}C_4 = 17550[/tex]
Next, we calculate ways of selecting 4 Canadians from 18 is:
[tex]^{18}C_4 = \frac{18!}{(18-4)!4!}[/tex]
[tex]^{18}C_4 = \frac{18!}{14!4!}[/tex]
[tex]^{18}C_4 = \frac{18*17*16*15*14!}{14!4!}[/tex]
[tex]^{18}C_4 = \frac{18*17*16*15}{4!}[/tex]
[tex]^{18}C_4 = \frac{18*17*16*15}{4*3*2*1}[/tex]
[tex]^{18}C_4 = \frac{73440}{24}[/tex]
[tex]^{18}C_4 = 3060[/tex]
The required probability is:
[tex]Probability =\frac{3060}{17550}[/tex]
[tex]Probability =0.1744[/tex]

Answer:
x = 90
Step-by-step explanation:
The 90-degree angle and "x" form a straight line. The degree measurement of a straight line is 180. That means that if one adds 90 and "x", they will get 180, and therefore, x equals 90.

Solve for x if y = 3 in the equation 2x + 3y = 12 *
Answers
Answer:
x = 3/2 or 1.5
Step-by-step explanation:
y = 3 in the equation 2x + 3y = 12
Substitute 3 in for y.
2x + 3(3) = 12
Multiply.
2x + 9 = 12
Subtract 9 from both sides.
2x + 9 - 9 = 12 - 9
2x = 3
Divide both sides by 2.
2x ÷ 2 = x
3 ÷ 2 = 3/2 or 1.5
x = 1.5
Answer:
X = 1.5
Step-by-step explanation:
So we know that Y = 3 and 3 x 3 = 9, then we need to get the difference of 9 to 12
12 - 9 = 3
we now know that x will equal 3, so 2 x 1.5 = 3, and 3 + 9 = 12
(Full equation)
2 x 1.5 + 3 x 3 = 12

to (7x1/

A 36.074
B 7,256.05
C 64.387
D 769.21
Answers
Answer:
It would be C, 64.387
Step-by-step explanation:
First, you have to solve 7x1/1000. This equal to 7/1000 which should be converted into decimal form (since all the answers are in decimal form). 7/1000 is 0.007 in decimal form.
It is 0.007 since in 7/1000, the denominator is 1000, making 7 in the thousandths place (the 3rd digit to the right of the decimal point).
The only number that contains 0.007 is the 3rd one, making it your answer.
