Here,

n = 11

mean = 7

Standard Deviation (σ) = 3

S.E. = ?

We know that,

S.E. = σ/\sqrt{n}

S.E. = 3/\sqrt{11}

∴ S.E. = 0.905 Ans.

<h3>Answer: Angle Q = 133 degrees</h3>

========================================================

Work Shown:

Recall that for any triangle, the three angles always add to 180

P+Q+R = 180

(x+13) + (10x+13) + (2x-2) = 180

(x+10x+2x) + (13+13-2) = 180

13x+24 = 180

13x = 180-24

13x = 156

x = 156/13

x = 12

Now that we know x, we can find the angle measures

  • angle P = x+13 = 12+13 = 25 degrees
  • angle Q = 10x+13 = 10*12+13 = 120+13 = 133 degrees
  • angle R = 2x-2 = 2*12-2 = 24-2 = 22 degrees

As a way to check if we have the right answer or not, we see that,

P+Q+R = 25+133+22 = 180

So the answer is confirmed.

Rice weighing 33/4 pounds was divided equally and placed in 4 containers. How many ounces of rice were in each?
QveST [7]

Answer:

The answer is 15 ounces

Step-by-step explanation:

33/4 ÷ 4 pounds.

(4 × 3 + 3)/4 ÷ 4 pounds.

15/4 ÷ 4 pounds.

15/4 × 1/4 pounds.

15/16 pounds.

Now we know that, 1 pound = 16 ounces.

So, 15/16 pounds = 15/16 × 16 ounces = 15 ounces.

Thus, The answer is 15 ounces

Chloe has been offered a new job in the women’s shoe department at Macy’s. She has two salary options. She can receive a salary
Umnica [9.8K]
The equations that represent the salary that Chloe's receive under the different options are:

1) Option 1: $600

2) Option 2: $ 350 + 8% * x, where x is the sales.

Using the fact that 8% = 0.08

Option 2 = $350 + 0.08x

A) If she has $3200 weekly salary:

Option 1 gives $600 (it is a constant salary)

Option 2 gives: $350 + $ 0.08 (3200) = $350 + $256 = 606.

Then, she will earn more money with the option 2.

B) The equation that can be used to determine when she earns more is found by making the two options equal:

Optio 1 = Option 2 =>

600 = 350 + 0.08x

C) Option 1 wiil lead to a greater earn when 600 > 350 + 0.08x

=> 600 - 350 > 0.08x

=> 250 > 0.08x

=> (250 / 0.08) >  x

=> 3,125 > x => x < 3,125

Then, the answer is that she will earn more money with option 1 when x < 3,125
