The equation f = v + at represents the final velocity of an object, f, with an initial velocity, v, and an acceleration rate, a,
Elenna [48]

Answer:

(f-v)/a = t

Step-by-step explanation:

f = v + at

Subtract v from each side

f-v = v-v + at

f-v = at

Divide each side by a

(f-v)/a = at/a

(f-v)/a = t

inessss [21]

Answer:

The required inequality is: 6\leq x

Step-by-step explanation:

Consider the provided information.

Gurnaz has been mowing lawns to save money for a concert. Gurnaz will need to work for at least six hours to save enough money, but he must work fewer than 16 hours this week.

Let the number of hours Gurnaz work is represented by x.

Gurnaz will need to work for at least six hours to save enough money,

That means he can work 6 or more than 6 hours,

x\geq 6

He must work fewer than 16 hours this week. That means the value of x should be less than 16.

x

Thus, the required inequality is: 6\leq x

Now draw the graph of the inequality.

Use a dot or close circle to represents ≤ or ≥ and use a open circle to represent < or >.

The value of x is greater than or equal to 6 also the value of x is less than 16. The required graph is shown below.

Suppose you obtain a chi-square statistic of 67.81. Are your results statistically significant if the critical value obtained fr
Svetach [21]

Answer:

Result is statistically significant.

Step-by-step explanation:

Given that :

Chisquare statistic, χ² = 67.81

Critical value for the distribution, χ²critical = 3.84

α = 0.05

The Decison region :

If χ² statistic > Critical value ; Reject H0 ; this. Eans that result is statistically significant.

Therefore, since, 67.81 > 3.84 ; This means that the result is statistically significant at 0.05
