Please help I’m having trouble understanding this question

Nikolay [14]

Answer: <1 = 26°

Step-by-step explanation:

given that:

• <ABD = 66°

• <2 = 14° + <1 (since ''more than' means we add)

• Find <1

Since it is obvious that <ABD is a sum of <1 and <2:

⇒ <ABD = <1 + <2

now we know that <2 is 14° more than <1 and that <ABD = 66°

⇒ 66° = <1 + (14° + <1)

⇒ 66° = <1 + 14° + <1

⇒ <1 = (66° - 14°) ÷ 2

⇒ <1 = 26° ...Answer...

hope that helps...

If twice a number, added to 3 is divided by the number plus 7, the result is five thirds. Find the number.

Alina [70]

Answer: 26

Step-by-step explanation:

Let the number be n.

Now,

twice a number =>> 2n

added to 3 =>> 2n + 3

is divided by the number plus 7 is five thirds =>> (2n + 3) / (n + 7) = 5 / 3

(2n + 3) = (5 / 3) × (n + 7)

3 × (2n + 3) = 5 × (n + 7)

6n+9 = 5n + 35

6n - 5n = 35 - 9

n = 26

A study of an association between which ear is used for cell phone calls and whether the subject is left-handed or right-hande

harina [27]

Answer:

Of the 5000 surveys, 14% were returned. This response rate APPEARS to be low.

Step-by-step explanation:

Given:

Total sample collected = 5000

Survey returned = 700

i) What percentage of the 5000 surveys were returned?

To find percentage returned, we have:

$= \frac{700}{5000} * 100 = 14 percent$

Percentage returned = 14%

ii) Does that response rate appear to be low?

Yes, the response is significantly low as only 14% is returned out of expected 100%

iii) In general, what is a problem with a very low response rate?

The problem with in low response rate in general is that it causes the result to be biased as biased samples of those interested in a particular aspect may have been gotten.

Therefore, of the 5000 surveys, 14% were returned. This response rate APPEARS to be low.

Subtract: (b^2 + 9 ab + 5a ) - ( 3b^2 -25ab + 1)

Brrunno [24]

Answer:

- 2b^2 + 34ab + 5a - 1

Step-by-step explanation:

here's your solution

=> (b^2 + 9ab + 5a) - (3b^2 - 25ab + 1)

=> b^2 + 9ab + 5a - 3b^2 + 25ab - 1

=> - 2b^2 + 34ab + 5a - 1
