Ipatiy [6.2K]

Answer:

No, the phone will be $6.24 over from $80

the tax is 7.84

Step-by-step explanation:

For sale:

98 ÷ 1.25 = 78.4

Tax:

78.4 x 1.1 = 86.24 <- Total price with sale and tax.

(86.24 > 80) ❌

86.24 - 78.4 = 7.84 <- Tax amount

At a stop sign, some drivers come to a full stop, some come to a rolling stop' (not a full stop, but slow down), and some do not

Natasha2012 [34]

Answer:

Option C.

Step-by-step explanation:

Given information:

Male-Full stop = 6, Male-Rolling stop = 16, Male-No stop = 4

Female-Full stop = 6, Female-Rolling stop = 15, Female-No stop = 3

Using the given information we get

Total number of males = 6 + 16 + 4 = 26

Total number of males = 6 + 15 + 3 = 24

Probability of No stop is

$p=\dfrac{\text{No-stop}}{Total}$

$p=\dfrac{4+3}{50}$

$p=\dfrac{7}{50}$

We need to find the number of males that would we expect to not stop at all.

Expected number of males = Number of males × Probability

Expected number of males = $26\times \dfrac{7}{50}$

Expected number of males = $3.64$

Therefore, the correct option is C.
