Marissa has a goal of shooting exactly 400 three–pointers during her basketball practice every week. She has already shot 105 of

m_a_m_a [10]

Answer: 5t = 400-105

Step-by-step explanation:

Let t= Number of three–pointers Marissa has to average over the next 5 days to reach her goal. .

Goal = 400 three–pointers every week.

Marissa has already shot = 105 three–pointers

Remaining shots to achieve target (5t) = Goal - (Marissa has already shot)

i.e. 5t = 400-105 (required equation)

⇒ 5t = 295

⇒ t = 59

hence, she need to make 59 shots per day for next 5 days.

there are 27 more green cars than black cars in the parking lot. What percentage of the cars in the parking lot are green? What

Yanka [14]

Answer:

Black is 3.57%

Green is 96.43%

Step-by-step explanation:

Since 27 green than black

Let the black car be b

So green cars which 27 more than black means 27b

So to calculate the percentage of green we will have

27b/27b+b ×100

27b/28b ×100

Let's eliminate the b

27/28×100

2700/28

96.43%

So let's calculate for Black

b/27b+b ×100

b/28b ×100

Eliminate b

1/28 ×100

100/28

3.57%

Therefore the percentage for Black is 3.57% and for green is 96.43%

Yahoo creates a test to classify emails as spam or not spam based on the contained words. This test accurately identifies spam (

Amiraneli [1.4K]

Answer and Step-by-step explanation:

The computation is shown below:

Let us assume that

Spam Email be S

And, test spam positive be T

Given that

P(S) = 0.3

$P(\frac{T}{S}) = 0.95$

$P(\frac{T}{S^c}) = 0.05$

Now based on the above information, the probabilities are as follows

i. P(Spam Email) is

= P(S)

= 0.3

$P(S^c) = 1 - P(S)$

= 1 - 0.3

= 0.7

ii. $P(\frac{S}{T}) = \frac{P(S\cap\ T}{P(T)}$

$= \frac{P(\frac{T}{S}) . P(S) }{P(\frac{T}{S}) . P(S) + P(\frac{T}{S^c}) . P(S^c) }$

$= \frac{0.95 \times 0.3}{0.95 \times 0.3 + 0.05 \times 0.7}$

= 0.8906

iii. $P(\frac{S}{T^c}) = \frac{P(S\cap\ T^c}{P(T^c)}$

$= \frac{P(\frac{T^c}{S}) . P(S) }{P(\frac{T^c}{S}) . P(S) + P(\frac{T^c}{S^c}) . P(S^c) }$

$= \frac{(1 - 0.95)\times 0.3}{ (1 -0.95)0.95 \times 0.3 + (1 - 0.05) \times 0.7}$

= 0.0221

We simply applied the above formulas so that the each part could come
