Answer:

Step-by-step explanation:

Ok let start by putting a set amount of hats, let start with 12, 8 times 12 equals 96, 200-96 is 104… I would subtract 8 until you get a number you can divide equally by 10, 104-8=96, 96-8 =88 , 88-8=80, there is 80 dollars left! Ok 80 divide by 10 = 8 so

8 shirts and we’ll we started at 12 and then we add how many more time we subtracted 8 so 15 total,

So, in total 8 shirts and 15 hats!!!

The area of the base of a triangular pyramid with faces that are equilateral triangles is 64 ft squared. Can you find the surfac
tankabanditka [31]

Answer:

C.

Step-by-step explanation:

Yes, because the area of the base of a triangular pyramid with equilateral triangles for faces is the same as the area of each face.

So the surface area is 64 * 4 which is 256

Shannon and Kelly spent $135 on gift certificates for their friends during the holidays. If this amount is 5/7 their total spend
Katena32 [7]

Answer:

$189

Step-by-step explanation:

Let their total amount of spending money be x

given that $135 they spent is 5/7 of their total spending money,

mathematically:

135 = (5/7) x     (multiply both sides by 7)

135 (7) = 5x

945 = 5x

5x = 945  (divide both sides by 5)

x = 945 / 5

x = 189

Philip Morris wishes to determine if there is a difference between the proportion of women and proportion of men who smoke cigar
uranmaximum [27]

Answer:

Step-by-step explanation:

This is a test of 2 population proportions. Let 1 and 2 be the subscript for the women and men who smoke respectively. The population proportion of women and men who smoke would be p1 and p2 respectively.

p1 - p2 = difference in the proportion of women and men who smoke.

The null hypothesis is

H0 : p1 = p2

p1 - p2 = 0

The alternative hypothesis is

Ha : p1 > p2

p1 - p2 > 0

it is a right tailed test

Sample proportion = x/n

Where

x represents number of success(number of complaints)

n represents number of samples

For women

x1 = 14

n1 = 110

p1 = 14/110 = 0.13

For men,

x2 = 7

n2 = 95

p2 = 7/95 = 0.07

The pooled proportion, pc is

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

pc = (14 + 7)/(110 + 95) = 0.1

1 - pc = 1 - 0.1 = 0.9

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

z = (0.13 - 0.07)/√(0.1)(0.9)(1/110 + 1/95)

z = 1.47

From the options given, the test statistic is

e. none of these is correct.

Since it is a right tailed test, we will look at the area to the right of z = 1.47. The p value would be

p value = 1 - 0.9292 = 0.078

Since alpha, 0.005 < than the p value, 0.078, then we would fail to reject the null hypothesis. Therefore, the data does not indicate that the proportion of women who smoke cigarettes is higher than the proportion of men who do at α=.005

3(9x-9)=16+3(-2x+9) please help me
Maru [420]
<span>3(9x-9)=16+3(-2x+9)
27x - 27 = 16 - 6x + 27
27x + 6x = 16 + 27 + 27
33x = 70
x = 70/33
x = 2 4/33

In short, Your Answer would be 70/33 or 2 4/33 

Hope this helps!</span>

Help due now pleaseee
DENIUS [597]

Answer:

d

Step-by-step explanation:

base² + Altitude² = Hypotenuse²

 x² + 9² = 13²

x² + 81 = 169

       x² = 169 - 81

      x² = 88

      x = \sqrt{88}

     x = \sqrt{2*2*2*11}=2\sqrt{2*11}\\\\x=2\sqrt{22}
