If you look at the red blue and purple dots you can see that they form a straight line. if you connected the green dot to the line it would make the line not straight, therefore the relationship is not proportional.

(6, 11) is your answer

Which of the following are solutions to the equation below? Check all that apply. (3x - 5)2 = 19 O A. x= 19+ olm B. x= 119 +5 I
asambeis [7]

Solution

(3x-5)^2=19

For this case we can take square root in both sides and we have:

3x-5=\pm\sqrt[]{19}

And solving for x we got:

x=\frac{5\pm\sqrt[]{19}}{3}

then the solutions for this case are:

B and E

Find the measure of the missing angles.<br> 147°<br><br> d =<br> e =<br><br> f=
Debora [2.8K]

Answer:

D = 90°

E = 147°

F = 33°

Step-by-step explanation:

E:

E is 147°, because it is vertical to the angle 147°

F:

F is 33°, because 147* is its supplementary angle, or angles that add up to 180°

D:

D is worth 90°, because its supplement is worth 90°

Find the slope of each line
sladkih [1.3K]

Step-by-step explanation:

To find the Slope of each line, pick two points you can clearly identify on each graph. The first graph has a point (-5,5) and (4,-5). Using these two points find the difference of the y coordinates divided by the difference in the x coordinates, like this:

5 - (-5). = 10

-5 - 4 = - 9

So the Slope is - 10/9

Same steps for all. Your equation is

(y1 - y2) / (x1 - x2)

Zucchini weights are approximately normally distributed with mean 0.8 pound and standard deviation 0.25 pound. Which of the foll
Charra [1.4K]

Answer:

0.81859

Step-by-step explanation:

We solve using z score method

The formula for calculating a z-score is is z = (x-μ)/σ,

where

x is the raw score

μ is the population mean

σ is the population standard deviation.

Mean 0.8 pound

Standard deviation 0.25 pound

For x = 0.55 pound

z = 0.55 - 0.8/0.25

= -1

Probability -value from Z-Table:

P(x = 0.55) = 0.15866

For x = 1.3 pounds

Z = 1.3 = 0.8/0.25

= 2

Probability value from Z-Table:

P(x = 1.3) = 0.97725

The probability that a randomly selected zucchini will weigh between 0.55 pound and 1.3 pounds is

P(x = 1.3) - P(x = 0.8)

0.97725 - 0.15866

0.81859.
