What formula to use <br> Answer

77julia77 [94]

Check the picture below.

now, since we know what "f" is, let us use the CNT triangle with the small COR one.

$\bf \cfrac{36+f+30}{36}=\cfrac{48+32+g}{48}\implies \cfrac{36+24+30}{36}=\cfrac{48+32+g}{48} \\\\\\ \cfrac{90}{36}=\cfrac{80+g}{48}\implies \cfrac{5}{2}=\cfrac{80+g}{48}\implies 240=160+2g \\\\\\ 80=2g\implies \cfrac{80}{2}=g\implies 40=g$

The voltage in a circuit is the product of two factors, the resistance and the current. If the voltage is 6ir + 15i + 8r+20, fin

zhuklara [117]

Answer:

resistance: (2r +5)
current: (3i +4)

Step-by-step explanation:

The factors of the given expression are ...

6ir +15i +8r +20 = (3i +4)(2r +5)

Which factor is current and which is resistance is not clear. Usually, resistance is referred to using the variable r, so we suppose the expressions are supposed to be ...

resistance: (2r +5)

current: (3i +4)

Gelneren [198K]

The elevations of four points below sea level are -47 feet, -24 feet, -8 feet, and -18 feet.

The elevation of the point closest to sea level is feet

-8 ft

elevation of the point farthest from sea level is feet.

-47 ft

closet to sea level to farthest to sea level

-8ft , -18ft , -24ft , -47ft

Tanya [424]

Answer:

a) Margin of error = 166.311

b) sample size ≥ 62

Step-by-step explanation:

Given:

Average cost = $1599

Sample size = 50 persons

Standard deviation = $600

Confidence level is 95%

a) Margin of error = $z\frac{\sigma}{\sqrt{n}}$

Now for confidence level of 95% z-value = 1.96

Thus,

Margin of error = $1.96\frac{600}{\sqrt{50}}$

or

Margin of error = 166.311

b) For Margin of error ≤ 150

$z\frac{\sigma}{\sqrt{n}}$ ≤ 150

or

$1.96\frac{600}{\sqrt{n}}$ ≤ 150

or

$1.96\frac{600}{150}$ ≤ √n

or

√n ≥ 7.84

or

n ≥ 61.4656

Therefore,

sample size ≥ 62

, find a1 and d. 34, 40, 46, 52, 58, 64

yulyashka [42]

Answer:

a1 = 34, d = 6.

Step-by-step explanation:

a1 = the first term = 34.

To find d subtract: 2nd term - first term , third term - second term and so on.

d = 40 - 34 = 6.

Also 46-40 = 6

WE get the same value 6 for the other given terms.

6 is added to each term to get the next term
