As in this figure two sides of triangle are equal so angle A=B because angle opposite to equal sides are equal so

60+x+x= 180
60+2x=180
2x= 180-60
2x=120
x=120/2
x=60
Therefore B,C is 60

Estimate of the standard error of the mean = 0.38 lb

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ = 10.87 lb

Sample size, n = 131

Standard deviation, σ = 4.31 lb

We have ti find the estimate of the standard error of the mean.

Formula for standard error:

$S.E= \dfrac{\sigma}{\sqrt{n}}$

Putting values, we get,

$S.E = \dfrac{4.31}{\sqrt{131}} = 0.3766 \approx 0.38$

0.38 lb is the standard error of the mean.

Elena-2011 [213]

Answer:

The 2 integers would be: 2 and 8

Step-by-step explanation:

2 + 8 = 10

Reciprocal of 2: 1/2

Reciprocal of 8: 1/8

1 / 2 - 1 / 8 = 4/8 - 1/8 = <u>3/8</u>

A yo-yo factory has fixed operating costs of $5000 per day plus costs of $2 per yo-yo produced. If a yo-yo sells for $5.50, what

Jlenok [28]

Answer:

1429

Step-by-step explanation:

Break even is expressed as:

5000+2x = 5.5x

5000=5.5x-2x

5000=3.5x

$\frac{5000}{3.5} = \frac{3.5x}{3.5}$

1428.57=x

Since you cannot sell a fractional yo-yo, round up to 1429
