I'm pretty sure it's double the longest side

Find the volume of the prism:

Margarita [4]

Answer:

168 units cubed

Step-by-step explanation:

so we know it's base times height right

so like identifying the base doesn't matter as long as you're smart enough to figure how to calculate then whatever lol

so like the base let's just say it's the triangle because that's probably what you're struggling on

so the base of the triangle is like what lol 6 * 8 / 2 = 48 / 2 = 24 so then you have the base multiply by the third dimension

24 * 7 = 140 + 28 = 168 so yeaaaaaaa and it's cubed because it's three dimensional

In a large population, 76% of the households have cable tv. A simple random sample of 225 households is to be contacted and the

serious [3.7K]

Answer:

0.017559

Step-by-step explanation:

Data provided:

Probability of Households Having cable TV, p₀ = 76% = 0.76

Therefore,

The probability that the Households not having cable TV = 1 - 0.76 = 0.24

Sample size, n = 225 households

sample proportions is less than 82% i.e p = 0.82

Now,

The standard error, SE = $\sqrt{\frac{p_0(1-p_0)}{n}}$

or

SE = $\sqrt{\frac{0.76(1-0.76)}{225}}$

or

SE = 0.02847

and,

$Z=\frac{p-p_0}{SE}$

or

$Z=\frac{0.82-0.76}{0.02847}$

or

Z = 2.107

therefore,

P(sample porportions < 0.82) = P(Z < 2.107)

now from the p value from the Z table

we get

P(sample porportions < 0.82) = 0.017559

aleksley [76]

Answer:

b. (3,0)

e. (5,-6)

f. (2,1)

Are solutions to the system of inequalities

Step-by-step explanation:

b. (3,0)

0 ≤ -2(3) + 6

0 ≤ 0 is true

3 > 1 is true

e. (5,-6)

-6 ≤ -2(5)+6

-6 ≤ -4 is true

5 > 1 is true

f. (2,1)

1 ≤ -2(2)+6

1 ≤ 2 is true

2 > 1 is true

If you draw a card with a value of three or less from a standard deck of cards, I will pay you $43. If not, you pay me $11. (Ace

valina [46]

If $W$ is a random variable representing your winnings from playing the game, then it has support

$W=\begin{cases}43&\text{if you draw something with value at most 3}\\-11&\text{otherwise}\end{cases}$

There are 52 cards in the deck. Only the 1s, 2s, and 3s fulfill the first condition, so there are 12 ways in which you can win $43. So $W$ has PMF

$P(W=w)=\begin{cases}\frac{12}{52}=\frac3{13}&\text{for }w=43\\1-\frac{12}{52}=\frac{10}{13}&\text{for }w=-11\\0&\text{otherwise}\end{cases}$

You can expect to win

$E[W]=\displaystyle\sum_ww\,P(W=w)=\frac{43\cdot3}{13}-\frac{11\cdot10}{13}=\boxed{\frac{19}{13}}$

or about $1.46 per game.
