writing to explain the table shows the average speed in kilometers per hour for two different racers A and B. in 12 hours ,how m
I am Lyosha [343]
Okay so because we are talking about the rate of km per hour. This means that car A is going 208km per hour. We are trying to find out how many km at 12 hours so we are going to multiply:
208x12= 2496km
Now we have to do the same for car B:
215x12= 2580km
Next we have to figure out how many km more did car B drive than car A so we have to subtract:
2580-2496= 84km
Hope this helps(;

I dont know how to do this, i mean i do but its hard
Brilliant_brown [7]

Answer:

Step-by-step explanation:

opposite= 8 : the length opposite angle c

adjacent=15 : the length next to angle c, not the hypotenuse

hypotenuse= 17 : the hypotenuse will always be opposite the right angle

sinC=\frac{opposite}{hypotenuse}\\ \\sinC=\frac{8}{17}

cosC=\frac{adjacent}{hypotenuse}\\\\cosC=\frac{15}{17}

tanC=\frac{opposite}{adjacent} \\\\tanC=\frac{8}{15}

Calculating the degrees of freedom, the sample variance, and the estimated standard error for evaluations.
ki77a [65]

Answer:

The variance is  \sigma ^2  =25

Step-by-step explanation:

From the question we are told that

    The sample size is  n =  21

     The sum of squares is SS =  500

Generally the variance is mathematically represented as

           \sigma ^2  = \frac{SS}{n- 1}

substituting values

          \sigma ^2  = \frac{ 500}{21- 1}

          \sigma ^2  =25
