James surveyed people at school and asked whether they bring their lunch to school or buy their lunch at school more often. The

Brrunno [24]

Answer:

The correct option is 4.

Step-by-step explanation:

Given information:

Bring lunch : 46 males, 254 females

Buy lunch : 176 males, 264 females

Total number of peoples is

$46+254+176+264=740$

Total number of males is

$46+176=222$

The probability of male is

$P(Male)=\frac{Males}{Total}=\frac{222}{740} =0.3$

Since probability of males is 0.3, therefore options A and C are incorrect.

Total number of persons who buys lunch is

$176+264=440$

The probability of persons who buys lunch is

$P(\text{Buys lunch})=\frac{\text{Buys lunch}}{Total}=\frac{440}{740} =\frac{22}{37}$

We need to find the probability of P(male | buys lunch).

According to the conditional probability, we get

$P(\frac{A}{B})=\frac{P(A\cap B)}{P(B)}$

P(male | buys lunch) $=\frac{P(\text{male }\cap \text{ buys lunch})}{P(\text{buys lunch})}$

P(male | buys lunch) $=\frac{\frac{176}{740}}{\frac{22}{37}}$

P(male | buys lunch) $=\frac{2}{5}=0.4$

Therefore the correct option is 4.

blondinia [14]

Answer:

1,216 cm³

Step-by-step explanation:

Volume (composite space figure) = Volume (pyramid) + volume (prism)

⇒ [16 x 6 x 14 / 3] + [16 x 6 x 8]
⇒ 96 [14/3 + 8]
⇒ 96 [14/3 + 24/3]
⇒ 96 x 38/3
⇒ 32 x 38
⇒ 1,216 cm³

Plese help me with 5 math questions! 50 points and brainliest! But don't type anything in the answer box until pics are posted!!

lukranit [14]

1. $x-5\ \textgreater \ 2$

add 5 to both sides

$x\ \textgreater \ 3$

2. $x+2\ \textless \ -5$

subtract 2 from both sides

$x\ \textless \ -7$

3. $x-2\ \textless \ 2$

add 2 to both sides

$x\ \textless \ 4$ and it's the 4th graph option

4. $x+5 \geq 10$

subtract 5 from both sides

$x \geq 5$ and it's the 2nd graph option

5. $x-5\ \textgreater \ -10$

add 5 to both sides

$x\ \textgreater \ -5$

Answers:

1. 3rd option

2. 1st option

3. 4th option

4. 2nd option

5. 2nd option

Hope this helps!
