Answer:the value of the variance is 36

Step-by-step explanation:

The formula for determining variance is

Variance of a set of data = square of the standard deviation. If the standard deviation of a set of data is 6, then the value of the variance would be

Standard deviation^2 = 6^2 = 36

a_sh-v [17]

In unit of batches over days, let r be the planned rate and R be the actual increased rate. The difference between R and r is described as 10 shirts per day.

R-r=10

Rate Time Batches

Planned r 8 1

Actual R 7 1

$\left[\begin{array}{c}r=1/8&R=1/7&R-r=HowManyBatchesInTenShirts\end{array}\right]$

$1/7-1/8$ , the number of batches equivalent to 10 shirts.

$(1/56)*Batches=10*Shirts$

OneBatch=560*Shirts

Answer:

A = 58.7 degrees

B = 66.9 degrees

C = 34.1 degrees

Step-by-step explanation:

For <A:

Tan A = $\frac{opposite}{adjacent}$

Tan A = $\frac{23}{14}$

Tan A = 1.6

A = $Tan^{-1} 1.6$

A = 58.7 degrees

For <B:

Sin B = $\frac{opposite}{hypotenuse}$

Sin B = $\frac{23}{25}$

Sin B = 0.92

B = $Sin^{-1} 0.92$

B = 66.9 degrees

For <C:

Sin C = $\frac{opposite}{hypotenuse}$

Sin C = $\frac{14}{25}$

Sin C = 0.56

C = $Sin^{-1}0.56$

C = 34.1 degrees

What is the one-hundredth term in the sequence 14, 19, 24, 29, 34…?

anzhelika [568]

Rule: look at the sequence. It has the last number as 4 then 9 then for. 4 for odd numbers(odd term numbers like number 3,5 so on) so the last number of the 100 term is 9. It’s 509.

Can you please answer this

jasenka [17]

Answer:

Sum angle of triangle BHD = 180°

36 + 39 + BHD = 180

BHD = 180 - 36 - 39

= 105°

BHD + x° = 180° (straight angle)

105° + x° = 180°

x = 180 - 105

= 75°
