Q 5

Let the one white ball be $W_1,$

4 black balls be $B_1,\:B_2,\:B_3,\: B_4$

& 5 red balls be $R_1,\:R_2,\:R_3,\: R_4, \:R_5$

Therefore, sample space is given as:

$S= \{ W_1, \:B_1,\:B_2,\:B_3,\: B_4, \: R_1,\:R_2,\:\\\:\:\:\:\:\:\:\:\:\:\:\:\:R_3,\: R_4, \:R_5\}$

Q 6

Given number is: 112964333

sample space for above number can be given as:

$S= \{ 1, \:2,\:3,\:4,\: 6, \: 9\}$

Note: Digits appearing in a number more than one time will be written only once while writing sample space.

There ratio of boys to girls is 17:3 there are 740 people how many boys are there

julsineya [31]

Ratio of boys to girls= 17:3
number of people= 740

to find the number of boys out of 740 people, you have to add the ratio together and divide 740 by it. then multiply the answer by 17 because the ratio for boys is 17.

17+3=20

740÷20=37
37×17=629

answer= 629
hope this helps....

What is the solution set of the equation X/5 + x/2 =14?

JulijaS [17]

Answer:

x= 20

Step-by-step explanation:

Solve for x:

(7 x)/10 = 14

Multiply both sides of (7 x)/10 = 14 by 10/7:

(10×7 x)/(7×10) = 10/7×14

10/7×7/10 = (10×7)/(7×10):

(10×7)/(7×10) x = 10/7×14

10/7×14 = (10×14)/7:

(10×7 x)/(7×10) = (10×14)/7

(10×7 x)/(7×10) = (7×10)/(7×10)×x = x:

x = (10×14)/7

14/7 = (7×2)/7 = 2:

x = 10×2

10×2 = 20:

Answer: x = 20

Find the area of the triangle with vertices: q(3,-4,-5), r(4,-1,-4), s(3,-5,-6).

maw [93]

Answer:

(√6)/2 square units

Step-by-step explanation:

The area of a triangle is half the magnitude of the cross product of the vectors representing adjacent sides.

QR = (4-3, -1-(-4), -4-(-5)) = (1, 3, 1)

QS = (3 -3, -5-(-4), -6-(-5)) = (0, -1, -1)

The cross product is the determinant ...

$\text{det}\left|\begin{array}{ccc}i&j&k\\1&3&1\\0&-1&-1\end{array}\right|=-2i+j-k$

The magnitude of this is ...

|QR × QS| = √((-2)² +1² +(-1)²) = √6

The area of the triangle is half this value:

Area = (1/2)√6 . . . . square units

Maya says that value of the 6 in 0.006 is 1/10 of the value of the 6 in 0.6 . Is she correct? Explain

Nikolay [14]

Answer:

Maya is NOT correct as

$\frac{1}{1000}$ is 1/100 of the value $\frac{1}{10}$

Step-by-step explanation:

The value of 6 in 0.006 = $\frac{1}{1000}$

Also, the value of 6 in 0.6 = $\frac{1}{10}$

But, $\frac{1}{1000}$ is not 1/10 of the value $\frac{1}{10}$

as 1/10 of the value $\frac{1}{10}$ = $\frac{1}{100}$

Hence,Maya is NOT correct.

$\frac{1}{1000}$ is 1/100 of the value $\frac{1}{10}$
