Answer:


The solution is: 


$160 for booth + $16 needles = $176 as capital


$15 price to sell each scarf - $4 cost of the yarn to make

the scarf = $11 as profit


$176 / $11 = 16


The students must sell 16 pieces of scarves to get the

break even point of $176 for the capital

Omar has 3 1/14 cups of dough to make dumplings.If he uses 3/16 cup of dough for each dumpling,how many whole dumplings can Omar
Bumek [7]

Answer:

Omar can make 16 dumplings with some dough to spare

Step-by-step explanation:

you should convert each value to have the same denominator to make the equation easier

3 and 1/14 cups is the same as 43/14 cups of dough

so the total 43/14 needs to be divided by 3/16

43/14 divided by 3/16 = 43/14 * 16/3

=688/42 = 16.3809...

so Omar can make 16 dumplings with some dough to spare

What smaller angle is coterminal with 573°
Kobotan [32]

The positive coterminal angle is 213° and negative coterminal angle is -147° and -507°

<u>Explanation:</u>

Coterminal angles are two angles that are drawn in the standard position (so their initial sides are on the positive x-axis) and have the same terminal side

In other words, two angles are coterminal when the angles themselves are different, but their sides and vertices are identical.

Another way to describe coterminal angles is that they are two angles in the standard position and one angle is a multiple of 360 degrees larger or smaller than the other. That is, if angle A has a measure of M degrees, then angle B is co-terminal if it measures M +/- 360n, where n = 0, 1, 2, 3, ...

So,

When angle is 573° then the coterminal angle is

573° - 360 (1) = 213°

573° - 360(2) = -147°

573° - 360 (3) = -507°

Therefore, positive coterminal angle is 213° and negative coterminal angle is -147° and -507°

The makers of a smartphone have received complaints that the face recognition tool often doesn't work, or takes multiple attempt
cupoosta [38]

Answer:

Step-by-step explanation:

This is a test of 2 population proportions. Let 1 and 2 be the subscript for the new version and the old version. The population proportion of the time that the tool works for the new and old version would be p1 and p2 respectively.

p1 - p2 = difference in the proportion of the times that the tool works for the new and old version

The null hypothesis is

H0 : p1 = p2

p1 - p2 = 0

The alternative hypothesis is

H1 : p1 > p2

p1 - p2 > 0

it is a right tailed test

Sample proportion = x/n

Where

x represents number of success

n represents number of samples

For new version

p1 = 70/100 = 0.7

n1 = 80

x1 = n1p1 = 80 × 0.7 = 56

For old version,

p2 = 56/100 = 0.56

n2 = 75

x2 = n2p2 = 75 × 0.56 = 42

The pooled proportion, pc is

pc = (x1 + x2)/(n1 + n2)

pc = (56 + 42)/(80 + 75) = 0.63

1 - pc = 1 - 0.63 = 0.37

z = (p1 - p2)/√pc(1 - pc)(1/n1 + 1/n2)

z = (0.7 - 0.56)/√(0.63)(0.37)(1/80 + 1/75) = 0.14/0.07759993557

z = 1.8

Since it is a right tailed test, we will look at the area to the right of the z score on the normal distribution table to determine the p value. Therefore,

p = 1 - 0.9641 = 0.04

By using the p value,

Since 0.1 > 0.04, we would reject the null hypothesis. Therefore, at a significance level of 0.1, it can be concluded that the new version is performing better.
