A direct variation exist between x and y. When x=4, y=3. What is the value of y when x=10

scoray [572]

Answer:

$y = 7.5$

Step-by-step explanation:

Given

Direct variation implies that:

$y = kx$

Where k is the constant of variation.

$x=4; y=3$

Required

Find y when $x = 10$

$y = kx$

Make k the subject

$k = \frac{y}{x}$

For: $x=4; y=3$

$k = \frac{3}{4}$

For: $x = 10$

$k = \frac{y}{x}$ becomes

$k = \frac{y}{10}$

Substitute $k = \frac{3}{4}$

$\frac{3}{4} = \frac{y}{10}$

Make y the subject

$y = \frac{3}{4} * 10$

$y = \frac{3* 10}{4}$

$y = \frac{30}{4}$

$y = 7.5$

True or False: A race car driver tested his car for time from 0 to 60 mph, and for 20 tests obtained a mean of 4.85 seconds with

sattari [20]

Answer:

The given statement is false.

Step-by-step explanation:

We are given the following in the question:

95% confidence interval: (4.53,5.18)

Sample mean, $\bar{x}$ = 4.85 seconds

Sample size, n = 20

Alpha, α = 0.05

Sample standard deviation, σ = 1.47 seconds

Degree of freedom = n - 1 = 19

95% Confidence interval:

$\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 4 and}~\alpha_{0.01} = \pm 2.09$

$4.85 \pm 2.09(\dfrac{ 1.47}{\sqrt{20}} )\\\\ = 4.85 \pm 0.69 \\\\= (4.16 ,5.54)$

Thus, the calculated confidence interval is different from the given confidence interval.

Hence, the given statement is false.
