Two central angles are listed below.

luda_lava [24]

You have to put the two angles in the same units, because now the first one is in radians and the second one in degress.

To pass 1.38 radians to degrees you can use the ratio 180° / π radian = 1.

So 1.38 radian * 180° / 3,1416 = 79 °.

So the angle in the Column A is 2° wider than the angle in the Column B.

Help my grade depends on it

Veseljchak [2.6K]

Lily made $75.36 more than Layla did. If Layla raised her price to $1.00, she would still not make more money than Lily.

Use a proportion to find the number of cupcakes Lily makes in 8 hours. She bakes 7 cupcakes in 10 minutes; we want to know how many she makes in 8(60)=480 (since there are 8 hours and each hour is 60 minutes):

7/10 = x/480

Cross multiply:
7*480 = 10*x
3360 = 10x

Divide both sides by 10:
3360/10 = 10x/10
336 = x

Lily bakes 336 cupcakes.

She sells 2/3 of these; 2/3(336) = 2/3(336/1) = 672/3 = 224 cupcakes sold.

Each cupcake is sold for $1.29; 224(1.29) = 288.96

To find the number of cupcakes Layla makes in 8 hours, we set up a different proportion. We know she bakes 8 cupcakes in 12 minutes; we want to know how many she bakes in 8(60) = 480 minutes:

8/12 = x/480
8*480 = 12*x
3840 = 12x

Divide both sides by 12:
3840/12 = 12x/12
320 = x

She bakes 320 cupcakes. She sells 75% of those; 75% = 75/100 = 0.75:
0.75(320) = 240

Each of those 240 cupcakes sells for $0.89:
0.89(240) = 213.60

This means Lily makes 288.96-213.60 = 75.36 more than Layla.

If Layla raised her price to $1.00, she would make 1(240) = $240; this is still less than Lily.

PLEASE HELP !!! ILL GIVE BRAINLESS

OLEGan [10]

Answer:

a. ∠G = 180 - (90 + 32)

b. ∠G = 58°

c. ∠J = 180 - 58°

d. ∠J = 122°

Step-by-step explanation:

Angles are added to result in 180°

when the line is straight; thus:

∠G = 180 - (90 + 32)

∠G = 180 - 122

∠G = 58°

∠J = 180 - 58°

∠J = 122°

The statement "Yes, all the conditions for Inference have been met" is correct.

A t-test is a hypothesis-testing technique for analyzing the means of one or two populations. A t-test can be used to see if a single group differs from a known value, if two groups differ from each other (an independent two-sample t-test), or if paired measurements show a significant difference.

We have:

Null hypothesis:H0: μ1 – μ2 = 0,

Alternative hypothesis: Ha: μ1 – μ2 < 0

As it is mentioned that the samples are drawn randomly and mentioned that no skewness is observed, this Indicates that the distribution is approximately normal

The total number of readings = 10

Which is not more than 10% of the Population size.

Thus, the statement "Yes, all the conditions for Inference have been met" is correct.
