1/3 ( x - 10) = -4 ???​

Mathematics
1 answer:
Pepsi [2]3 years ago
4 0

Answer:

x =  - 2

Step-by-step explanation:

1) Simplify 1/3 ( x - 10) to x-10/3.

\frac{x - 10}{3}  =  - 4

2) Multiply both sides by 3.

x - 10 =  - 4 \times 3

Simplify 4 × 3 to 12.

x - 10 =  - 12

4) Add 10 to both sides.

x =  - 12 + 10

5) Simplify -12 + 10 to -2.

x =  - 2

So, therefor, the answer is, x = -2.

igor_vitrenko [27]

Answer:

84 Percentage increase

Step-by-step explanation:

Detailed calculations & verification

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

40% = 40/100 = 40 ÷ 100 = 0.4.

100% = 100/100 = 100 ÷ 100 = 1.

Increase the number by 40% of its value.

Percentage increase = 40% × 210

New value = 210 + Percentage increase

Calculate the New Value

New value =

210 + Percentage increase =

210 + (40% × 210) =

210 + 40% × 210 =

(1 + 40%) × 210 =

(100% + 40%) × 210 =

140% × 210 =

140 ÷ 100 × 210 =

140 × 210 ÷ 100 =

29,400 ÷ 100 =

294

Calculate absolute change (actual difference)

Absolute change (actual difference) =

New value - 210 =

294 - 210 =

84

The weights of steers in a herd are distributed normally. the standard deviation is 200 lbs and the mean steer weight is 1300 lb
Olin [163]
<span>Given a mean = 1300 and a Ď = 200, we can calculate that the lower bound of 1000 is (1000 - 1300) / 200 = -1.5 standard deviations below the mean. The upper bound is (1437 - 1300) / 200 = 0.685 standard deviations from the mean. Using the cumulative distribution function, we can calculate that the probability a randomly chosen steer lies on the interval [1000, 1437] is CDF(0.685) - CDF(-1.5) = 0.68652083824480004 p = 0.6865</span>
