Andre is in charge of cooking brócoli and zucchini for a large group he had to spend all 17$ he has and Cary 10 pounds of veggie
nataly862011 [7]

Answer:

This is an example of equation with two unknowns. Andre bought x pounds of zucchini and y pounds of broccoli and we also know that there was 10 pounds of veggies in total. So, we can write:

$1.5 • x + $2 • y = $17

x + y = 10

From the second equation we can say that:

y = 10 - x

We can now enter this value of y into the first equation:

1.5 • x + 2 • (10-x) = 17

1.5 • x + 20 - 2 • x = 17

1.5x - 2x = 17 - 20

-0.5x = -3

0.5x = 3

x = 6

If x=6, then y=10-6, which is 4.

That means that Andre bought 6 pounds of zucchini and 4 pounds of broccoli.

one town, 64% of adults have health insurance. What is the probability that 10 adults selected at random from the town all have
Katena32 [7]

Answer:

The probability that 10 adults selected at random from the town all have health​ insurance is 0.01153.

Step-by-step explanation:

Consider the provided information.

One town, 64% of adults have health insurance.

Let p = 64% = 0.64

Therefore, q=1-0.64=0.36

We need to find the probability that 10 adults selected at random from the town all have health insurance

Use the formula: P(x)=^nC_r(p)^r(q)^{n-r}

Here, the value of r is 10.

Substitute the respective values in the above formula.

P(x)=^{10}C_{10}(0.64)^{10}(0.36)^{10-10}

P(x)=(0.64)^{10}(0.36)^{0}\\P(x)=(0.64)^{10}\\P(x)\approx0.01153

Hence, the probability that 10 adults selected at random from the town all have health​ insurance is 0.01153.
