Dahasolnce [82]

Answer:

Q1. 1050 miles

Q2. 1h 30m

Step-by-step explanation:

Q1. 1h = 300 miles

3 $\frac{1}{2}$ h = 3.5 × 300 miles

= 1050 miles

Q2. 68km = 1h

102km = $\frac{102}{68}$ × 1h

= 1.5h

= 1h 30m

V. Money Magazine reported that the average price of gasoline in the United States during the first quarter of 2008 was $3.46. A

Butoxors [25]

Answer:

$z=\frac{3.43 -3.46}{\frac{0.15}{\sqrt{30}}} = -1.095$

$z=\frac{3.49 -3.46}{\frac{0.15}{\sqrt{30}}} = 1.095$

And we can find this probability using the normal standard table and we got:

$P(-1.095$

Step-by-step explanation:

Let X the random variable that represent the price of a population, and for this case we know the distribution for X is given by:

$X \sim N(3.46,0.15)$

Where $\mu=3.46$ and $\sigma=0.15$

And for this case we want to find the following probability:

$P(3.43 \leq \bar X \leq 3.49)$

And we can use the z score formula given by:

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

If we find the z score for the limits we got:

$z=\frac{3.43 -3.46}{\frac{0.15}{\sqrt{30}}} = -1.095$

$z=\frac{3.49 -3.46}{\frac{0.15}{\sqrt{30}}} = 1.095$

And we can find this probability using the normal standard table and we got:

$P(-1.095$

How do I solve for c

MrMuchimi

Answer:

c = 13

Step-by-step explanation:

pythogoras theorem

a² + b² = c²

5² = 25

12² = 144

25 + 144<em> </em>= 169

√169 = 13

c = 13
