Answer:
Car B is faster
Car B is ×1.125 times faster
Step-by-step explanation:
Car A:
went 60 km in 5/6 hour
then
went 60/5 = 12 km in 1/6 hour
then
went 12 ×6 = <u><em>72 km</em></u> in 6/6 = 1 hour
Car B:
went 54 km in 2/3 hour
then
went 54/2 = 27 km in 1/3 hour
then
went 27 × 3 = <u><em>81 km</em></u> in 3/3 = 1 hour
81÷72 = 1.125
Standard formula: Ax + By = C
y = 3x -3 + 2
y - 3x = -1 is the answer
hope this helps
Answer:
Normal; increases.
Step-by-step explanation:
In Statistics and probability, a student t-distribution also known as the t-distribution refers to the continuous probability distribution which can be used to estimate population parameters when the population variance or standard deviation is not known (unknown) and the sample population is relatively small. The student t-distribution is a statistical distribution which was published in 1908 by William Sealy Gosset.
The t-distribution approaches the normal distribution as the sample size increases because the parameters becomes negligibly smaller.
This ultimately implies that, when the degree of freedom of a t-distribution curve is increased in comparison with that of a normal distribution, the value of probability becomes significantly similar.
Answer:
n = -13
Step-by-step explanation:
38 = -2n + 12
<em>Subtracting</em><em> </em><em>1</em><em>2</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
==> 38 - 12 = -2n + 12 - 12
==> 26 = -2n
<em>multiplying both sides by (-1)</em><em>:</em>
==> -26 = 2n
<em>dividing</em><em> </em><em>both</em><em> </em><em>sides by 2:</em>
==> -13 = n
