Answer: M∠2 just mean measure of angle 2,

Step-by-step explanation: So I worked it out and the awnser is B.

3 numbers/the degrees of all 3 sides always add up to 180 degrees.

Side 1 is 60 degrees and the left side is 20, so 20 + 60 + 3 (unkown number) = 180

60 - 20 = 100,

A box with a square base and open top must have a volume of 97556 c m 3 cm3 . We wish to find the dimensions of the box that min

Kipish [7]

Answer:

S(x) = x² + 390224/x

Step-by-step explanation:

Volume of the open box = V = 97556 cm³

Material needed:

Let´s call x the side of the square base then the area of the base is

A(b) = x²

For the sides of the box, we have 4 sides each one with area of x*h

where h is the height of the box

The volume of the box V(b) = 97556 = x²*h then h = 97556/x²

S(x,h) = x² + 4*x*h*

The surface area of the box as function of x is:

S(x) = x² + 4*x*97556/x²

S(x) = x² + 390224/x

The director of a state agency believes that the average starting salary for clerical employees in the state is less than $30,00

ss7ja [257]

Answer:

The test statistics is $z = -1$

Step-by-step explanation:

From the question we are told that

The sample size is n = 100

The null hypothesis is $H_o : \mu = \$30000$

The alternative hypothesis is $H_a : \mu < \$ 30000$

The sample mean is $\= x = \$29,750$

The standard deviation is $\sigma = \$2,500$

The level of significance is $\alpha =0.05$

Generally the test statistics is mathematically represented as

$z = \frac{\= x - \mu }{ \frac{ \sigma}{ \sqrt{n} } }$

=> $z = \frac{29750 - 30000 }{ \frac{ 2500}{ \sqrt{100} } }$

=> $z = -1$
