3 There are 5 times as many boys as girls in a school.
Dafna1 [17]

Answer:

Number of boys = 675

Step-by-step explanation:

Given that:

There are 5 times as many boys as girls in a school.

Number of pupils in school = 810

Let,

x be the number of girls

y be the number of boys

According to given statement;

x+y=810      Eqn 1

y = 5x         Eqn 2

Putting y=5x in the Eqn 1

x+5x=810

6x=810

Dividing both sides by 6

\frac{6x}{6}=\frac{810}{6}\\x=135

Putting x=135 in Eqn 2

y = 5(135)

y = 675

Hence,

Number of boys = 675

The value of y varies directly with x, and y = 16 when x = 8. What is the value of x
Natali [406]

Answer:

A) 16

Step-by-step explanation:

y = kx

16 = k*8

16/8 = k

k = 2

y = 2x

32 = 2x

32/2 = x

16 = x

A probability experiment is conducted in which the sample space of the experiment is S 1,2,3,4, 5,6,7,8, 9, 10, 11, 12]. Let eve
Alenkinab [10]

Answer:

E\ n\ F = \{1, 5, 6,7\}

F\ n\ G =\{9\}

F\ U\ G =\{1,5,6, 7, 8,9,10, 11, 12\}

P(F\ U\ G) = \frac{3}{4}

Step-by-step explanation:

Given

S = \{1,2,3,4, 5,6,7,8, 9, 10, 11, 12\}

E = \{1,2, 3, 4, 5, 6,7\}

F =\{1,5,6, 7, 8,9\}

G = \{9,10, 11, 12\}

H = \{2, 3, 4\}

Solving (5): E and F

Sets of E and F = E n F

E\ n\ F = \{1,2, 3, 4, 5, 6,7\}\ n\ \{1,5,6, 7, 8,9\}

List out common elements

E\ n\ F = \{1, 5, 6,7\}

<em>They are not mutually exclusive because </em>n(E\ n\ F) \neq 0<em />

Solving (6): F and G

Sets of F and G = F n G

F\ n\ G =\{1,5,6, 7, 8,9\}\ n\ \{9,10, 11, 12\}

List out common elements

F\ n\ G =\{9\}

<em>They are not mutually exclusive because </em>n(F\ n\ G) \neq 0<em />

Solving (7): F or G and P(F or G)

Sets of F or G = F U G

F\ U\ G =\{1,5,6, 7, 8,9\}\ U\ \{9,10, 11, 12\}

List all elements without repetition

F\ U\ G =\{1,5,6, 7, 8,9,10, 11, 12\}

Solving P(F U G)

P(F\ U\ G) = \frac{n(F\ U\ G)}{n(S)}

n(F\ U\ G) = 9

n(S) = 12

Hence;

P(F\ U\ G) = \frac{9}{12}

Divide by 3

P(F\ U\ G) = \frac{3}{4}

I'm tired just did over 10 works help please thank you
Dafna11 [192]

Part A. For finding the quartiles, box plot would be the best to represent the range of scores of the students.

Part B. The first step is to order the data: 2 3 3 3 3 4 5 6 7 8 14. Next, you will find the median. The median is 4. So, second the quartile = 4 The median splits the remaining data into two sets. The first set is 2 3 3 3 3 and the median of this set is 3. So, first quartile = 3. The second set is 5 6 7 8 14 and the median of this set is 7. And the third quartile = 7
