It’s b

when you’re multiplying with an exponent, you’re multiplying that number however many times the exponent says, against itself. For example, seven to the third, is 7×7×7. So if you add seven to the third power plus the seven to the fourth power. You should get seven to the seventh power.

Which line contains the pint (6-4) and has a slope of -5/6
natima [27]

Answer:

y = - 5/6 x + 1

Step-by-step explanation:

y = mx + b      m: slope    b: y intercept

point (6 , -4)        x = 6     y = -4

b = y - mx = -4 - ((-5/6) x 6) = - 4 + 5 = 1

equation: y = - 5/6 x + 1

A concrete mix is designed to withstand 3000 pounds per square inch​ (psi) of pressure. The following data represent the strengt
ss7ja [257]

Answer:

Mean = 3640

Mode = 4100

Median = 3830.

Step-by-step explanation:

We are given the following data in the question:

Strength of casts (in psi):

3970,4100,3100,3200,2950,3830,4100,4050,3460

Formula:

Mean = \displaystyle\frac{\text{Sum of all observation}}{\text{Total number of observations}}

\displaystyle\frac{3970+4100+3100+ 3200+ 2950+ 3830+4100+ 4050+ 3460}{9} = \displaystyle\frac{32760} {9} = 3640

Mode is the entry with most frequency. Thus, for the given sample mode = 4100.

Median

Since n = 9 is odd,

Formula:

Median = \displaystyle\frac{n+1}{2}th~term

Data in ascending order:

2950,3100,3200,3460,3830,3970,4050,4100,4100

Median = 5th term = 3830.
