Mathematics
1 answer:
Diano4ka-milaya [45]4 years ago
7 0

Answer:

11/7 = (11 x 9)/(7 x 9) = 99/63 > 77/63

3/5 = (3 x 15)/(5 x 15) = 45/75

1/8 = (1 x 10)/(8 x 10) = 10/80

2/9 = (2 x 9)/(9 x 9) = 18/81

Hope this helps!

After two weeks of hard work at Sweet Sundae Ice Cream Shop, Zack finally got his first paycheck! He deposited $120.00 into his
Zielflug [23.3K]

Answer:

p - 120.00 = 56.74; p = $176.74.

Step-by-step explanation:

Out of the two equations, p - 120.00 = 56.74 would make the most sense. That is because it means that his paycheck minus the 120 that he deposited into savings is equal to the remaining balance.

We solve p - 120.00 = 56.74 by adding 120 to both sides.

p - 120 + 120 = 56.74 + 120

p = 176.74.

So, Zack got paid $176.74. That's a lot of money!

Hope this helps!

sergejj [24]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

H_0: Management quality and corporate reputation are independent.  

H_1:  Management quality and corporate reputation are not independent.

Test statistic:

\to \chi^2 = \frac{\sum (O-E)^2}{E}

= 0.71429 + 0.0102 +2.8809+0.625+1.75 +0.3333    +0+3.2143+7.5\\\\= 17.02806

The critical \chi^2 fordf = (r-1)(c-1) = (3-1)(3-1)= 4 and \alpha = 0.05 is \chi^2= 9.4877

Test statistic:

17.02806 > 9.4877 therefore rejecting the null hypothesis H_0.

p-value= 0.001909

Interpretation:

There is no internal governance quality as well as the reputation of the organization.

Which shows a perfect square trinomial?
12345 [234]

A perfect square trinomial is found in the expression where both the leading coefficients and the constant are both perfect squares. That only is the case with the third choice above. 16 is a perfect square of 4 times 4, and 9 is a perfect square of 3 times 3. We need to set it up into its perfect square factors and FOIL to make sure, so let's do that. Not only is 16 a perfect square in that first term, but so is x-squared. Not only is 9 a perfect square in the third term, but so is y-squared. So our factors will look like this:

(4x + 3y)(4x + 3y). FOIL that out to see that it does in fact give you back the polynomial that is the third choice down.

A total of 6.2 percent of the prime time viewing audience watched shows on ABC, 8.1 percent watched shows on CBS, 7.4 percent on
statuscvo [17]

Answer:

For each one it is shown below

Step-by-step explanation:

The computation of the prime time viewing percentage for the following data is shown below:l;

but before that we need do the total which is

= 6.2% + 8.1% + 7.4% + 6.4% + 3.1% + 2.8%

= 34%

Now for each one the viewing percentage is

For ABC

= \frac{6.2}{34}

= 18.24%

For CBS

= \frac{8.1}{34}

= 23.82%

For NBC

= \frac{6.4}{34}

= 18.82%

For Warner brothers

= \frac{3.1}{34}

= 9.12%

For fox

= \frac{7.4}{34}

= 21.76%

For UPN

= \frac{2.8}{34}

= 8.24%
