Need help with question 11 and 12

qaws [65]

Answer:

11. your choices are correct

12. 132°

Step-by-step explanation:

11. The given equations can be (re)written to slope-intercept form. Only those lines with a slope of 2 will be parallel to the given line.

A: y = 2x -8 . . . . . slope = 2, an answer

B: y = -2x +1 . . . . . slope = -2, not an answer

C: y = -2x +7 . . . . .slope = -2, not an answer

D: y = 2x +2 . . . . . slope = 2, an answer

E: y = -2x -9 . . . . . slope = -2, not an answer

12. The marked angles are supplementary, so ...

(3x -6)° +(x +2)° = 180°

4x -4 = 180 . . . . . . . . . . . divide by °, collect terms

x -1 = 45 . . . . . . . divide by 4

x = 46 . . . . . . . . . add 1

Now, we can find the angle of interest.

∠PQR = (3x -6)° = (3·46 -6)°

∠PQR = 132°

The red blood cell counts (in millions of cells per microliter) for a population of adult males can be approximated by a norma

skad [1K]

Answer:

(a) Minimum red blood cells 5.744 million cells per micro liter

(b) Maximum red blood cells 5.068 million cells per micro liter.

Step-by-step explanation:

Z-score formula is = $\frac{x-u}{Standard deviation}$

Z-score = $\frac{x-5.5}{0.4}$

The value of z-score is 0.61 so then x will be;

x = 5.744

The minimum red blood cells count that can in top is 27% of count which is 5.744 million cells per micro liter.

Z-score = $\frac{x-5.5}{0.4}$

The value of z-score is 0.14 so then x will be;

x = 5.068

The maximum red blood cells count that can be in top is 14% of count which is 5.068 million cells per micro liter.

What is the volume to the composite figure.

yarga [219]

Answer:

462 $cm^{3}$

Step-by-step explanation:

Rectangular Prism: 7 x 8 x 6 = 336

Triangular Prism: (0.5 x 7 x 6) x 6 = 126

336 + 126 = 462

Select the equivalent expression.

Vanyuwa [196]

For this case we must find an expression equivalent to: $(y ^ 3 * 2 ^ 5) ^ 2$

By definition of power properties we have to meet:

$(a ^ n) ^ m = a ^ {n * m}$

So, rewriting the expression we have:

$y^{3 * 2} * 2^ {5 * 2} =\\y^ 6 * 2^{10}$

Answer:

Option B

$y^6*2^{10}$
