Answer:

<em>Answer: A. 0.2</em>

Step-by-step explanation:

<u>Probability</u>

The circle graph shows the distribution of the makeup of the Riverside Municipal Choir.

The total number of choir sections is: 8+10+10+12=40

To calculate the probability of a member chosen at random comes from the alto section, we use the formula:

$\displaystyle P=\frac{8}{40}$

Calculating:

P = 0.2

B Jamal says that 18:12 and 3:4 are not equivalent ratios Margie says they are equivalent ratios who is correct

Hatshy [7]

Answer:

Jamal is correct.

Step-by-step explanation:

3:4 is equivalent to 9:12, not 18:12.

We can see that for 3:4, the left side is less than the right, but for 18:12, left side is greater than the right, which immediately tells us the ratios are not equivalent.

What is the equation of the line

olga2289 [7]

Answer:

It's the first choice y = (-5/2)x - 1.

Step-by-step explanation:

First find the slope of the line 5x + 2y = 12 by converting to slope-intercept form.

5x + 2y = 12

2y = -5x + 12

y = (-5/2)x + 6 so the slope is (-5/2).

The line we require had also a slope of -5/2 because it is parallel to the first line and it also passes through the point (-2, 4). So:

y - 4 = (-5/2)(x - -2) (the point-slope form)

y - 4 = (-5/2)(x + 2)

y = (-5/2)x - 5 + 4

y = (-5/2)x - 1 (answer)

Simplify the expression by using a double-angle formula or a half-angle formula. (a) cos2 θ 2 − sin2 θ 2

SCORPION-xisa [38]

If this is supposed to be
$cos^{2}θ-sin^{2}θ$
Then this can simply be reduced to
$cos2θ$
by the double angle formula for cosine
