4. ASAP I NEED HELP

vodomira [7]

Answer:

The value of x = 5 and y = 2.

Step-by-step explanation:

Here, given DECK is a parallelogram.

Also, KT = 2x + y , DT = x + 2y , TE = 12 and TC = 9

Now, in parallelogram:

DIAGONALS IN A PARALLELOGRAM BISECT EACH OTHER

Also, in the parallelogram DECK,

Sides DC and KE are two diagonals.

⇒ T is the mid point of AC and KE.

⇒ KT = TE and DT = TC ( as diagonals are bisected)

⇒ 2 x + y = 12 and x + 2y = 9

So here, the set of two equations are:

2 x + y = 12 ....... (1)

x + 2 y = 9 ....... (2)

Multiply (2) with -2 and add with (1), we get:

2 x + y - 2 x - 4 y = 12 - 18

or, - 3 y = - 6

or, y = 2

If y = 2, then x + 2 (2) = 9 or, x = 5

Hence the values of x = 5, y = 2

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.

If you triple 4 and subtract 2 each day, how many days until you have zero

Gnom [1K]

<span>Triple 4 and subtract 2 each day
Find the number of days to be able to reach zero
1st day = 3(4) – 2
=> 12 - 2
=> 10
2nd day
=> 10 - 2
=> 8
3rd day
=> 8 – 2
=> 6
4th day
=> 6 – 2
=> 4
5th day
=> 4 – 2
=> 2
6th day
=> 2 – 2
=0

In 6th day, you’ll be able to get the amount of zero by subtracting 3(4) by 2.</span>
