Answer:

the probability of observing 27 or more students 0.818

Step-by-step explanation:

given data

sample n = 28 students

population = 93%

to find out

the probability of observing 27 or more students

solution

we will find Z value for CI 93%

from z table we get Z is 1.812 for Cl 93%

so P(27 ≤ Z ≤ 28)

we know Z = 0.182

= 1 - 0.182

= 0.818

the probability of observing 27 or more students 0.818

Help and explain please and ty <3333

Anni [7]

Answer:

A. 693

Step-by-step explanation:

The question is asking you to input 7 into both functions and then multiply them together.

First insert 7 into f(x) = 7 + 2x, 7 times 2 is 14, plus 7 = 21

do the same with g(x) = 5x - 2, 5 times 7 is 35, minus 2 = 33

fg(7) is saying to multiply fg together as a variable next to another variable does. leaving the answer as 693.

a bag contains 5 red skittles, 3 purple skittles, and 2 orange skittles.A skittle is removed and not replaced, then another skit

dybincka [34]

The probability of two independant events $P_a$ and $P_b$ can be found by multiplying the individual probabilities like so:
$P_t=P_{a}*P_b$

For each individual probability we can find the answer via a simplfied representation:
$P_x = \frac{wanted}{total}$

For the first skittle (red) we have:
$P_{red} = \frac{red}{total}=\frac{5}{10}=0.5$

For the second skittle (orange) we have:
$P_{orange} = \frac{2}{9} = 0.2222...$
**(Notice that the total is now NINE since we didn't put the first red one back in the bag.)

So:
$P_{total} = P_{red} \times P_{orange}$
$P_{total} = \frac{5}{10} \times \frac{2}{9}$
$P_{total} = \frac{10}{90}=\frac{1}{9} \approx 0.1111 \approx 11.11\%$
