Answer:

It's acute triangle

Step-by-step explanation:

c^2 = 19^2 = 361

a^2 + b^2 = 15^2 + 13^2 = 225 + 169 = 394

c^ < a^2 + b^2 > . It's acute triangle

Place the following linear equation in slope intercept form: 6x - 4y = 9

geniusboy [140]

Answer:

y = 3/2 x - 9/4

Step-by-step explanation:

bring all the y's to one side.

4y = 6x-9

divide by 4 to isolate the y

y = 6/4x - 9/4

simplify

y = 3/2 x - 9/4

What’s the equivalent expression

r-ruslan [8.4K]

Answer:

9 (2 a - 3)^2

Step-by-step explanation:

Simplify the following:

(6 a - 9)^2

Hint: | Factor out the greatest common divisor of the coefficients of 6 a - 9.

Factor 3 out of 6 a - 9:

(3 (2 a - 3))^2

Hint: | Distribute exponents over products in (3 (2 a - 3))^2.

Multiply each exponent in 3 (2 a - 3) by 2:

3^2 (2 a - 3)^2

Hint: | Evaluate 3^2.

3^2 = 9:

Answer: 9 (2 a - 3)^2

According to the Centers for Disease Control and Prevention (CDC) , 47% of adults in the United States have hypertension. In a r

harina [27]

The probability that sample the proportion of adults with hypertension is greater than 0.5 is 0.090

<h3>How to determine the probability?</h3>

The given parameters are:

p = 47%

Sample size, n =500

The standard deviation is calculated as:

$\sigma = \sqrt{np(1 - p)$

So, we have:

$\sigma = \sqrt{500 * 47\%(1 - 47\%)$

Evaluate

σ = 11.16

The number of adults with hypertension is calculated as:

x = 500 * 0.5 = 250

And the mean is:

μ = 500 * 0.47 = 235

Start by calculating the z-score

$z = \frac{x - \mu}{\sigma}$

This gives

$z = \frac{250 - 235}{11.16}$

Evaluate

z = 1.34

The probability is then calculated as:

P(z >1.34) = ??

From z table of probabilities, we have:

P(z >1.34) = 0.090

Hence, the probability that sample the proportion of adults with hypertension is greater than 0.5 is 0.090
