Answer:

y = 5x - 11

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here slope m = 5, hence

y = 5x + c ← is the partial equation

To find c substitute (1, - 6) into the partial equation

- 6 = 5 + c ⇒ c = - 6 - 5 = - 11

y = 5x - 11 ← equation of line

Answer: 0.0136

Step-by-step explanation:

Given : Mean : $\mu=\ 25$

Standard deviation : $\sigma= 3.2$

Sample size : $n=50$

The formula to calculate the z-score :-

$z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

For x = 24

$z=\dfrac{24-25}{\dfrac{3.2}{\sqrt{50}}}=-2.20970869121\aprox-2.21$

The P-value = $P(z\leq24)=0.0135526\approx0.0136$

Hence, the probability that the sample mean age for 50 randomly selected women to marry is at most 24 years = 0.0136

Complete the table and then graph the function.<br> y = x + 1 look at photo

JulsSmile [24]

Since y=x+1 you get your first x value which is 2 and add one which is 3. Your first coordinate is (2,3) now the second one is 5 so 5+1=6 meaning your coordinate is (5,6) and so on a so forth so technically just add one to the x able and use your x value and the new value you just solved for to create the new coordinate to graph

3^2 x 3^x =3^7 find the value of x

d1i1m1o1n [39]

3^2 • 3^x=3^(2+x)

3^(2+x)=3^7

=> 2+x=7

x=5
