Tanzania [10]

Answer:

B) [1, 4, 7]

Step-by-step explanation:

Substitute 0 in

f(0) = 3(0) + 1

Multiple

f(0) = 0 + 1

f(0) = 1

Substitute 1 in

f(1) = 3(1) + 1

f(1) = 3 + 1

f(1) = 4

Substitute 2 in

f(2) = 3(2) + 1

2 = 6 + 1

f(2) = 7

Answer:

The sample size is $n =33$

Step-by-step explanation:

From the question we are told that

The margin of error is E = 1.5 seconds

The standard deviation is s = 4 seconds

Given that the confidence level is 97% then the level of significance is mathematically represented as

$\alpha =( 100 -97)\%$

=> $\alpha = 0.03$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 2.17$

Generally the sample size is mathematically represented as

$n =[ \frac{Z_{\frac{\sigma }{2 } } * \sigma }{E} ]^2$

=> $n =[ \frac{2.17 * 4 }{1.5} ]^2$

=> $n =33$

The circle below is centered at (3, 1) and has a radius of 2. What is its<br> equation?

MissTica

Answer:

( x-3) ^2 + ( y-1) ^2 = 4

Step-by-step explanation:

The equation for a circle is given by

( x-h)^2 + ( y-k) ^2 = r^2 where (h,k) is the center and r is the radius

( x-3) ^2 + ( y-1) ^2 = 2^2

( x-3) ^2 + ( y-1) ^2 = 4
