GenaCL600 [577]

Answer:

The alternative hypothesis is $H_1: p > 0.6$ .

The critical value is $Z_c = 1.645$

Step-by-step explanation:

It is claimed that proportion in favor of proportion A is greater than 60%.

This means that at the null hypothesis, we test if the proportion is of at most 60%, that is:

$H_0: p \leq 0.6$

At the alternative hypothesis, we test if the proportion is more than 60%, that is:

$H_1: p > 0.6$

What is (are) the critical value?

The critical value is the value of Z with a p-value 1 subtracted by the standard significance level of 0.05, since we are testing if the mean is more than a value, so, looking at the z-table, $Z_c = 1.645$

If r = 4 and ^a8 = 100, what is the first term of the geometric sequence?

telo118 [61]

The first term of the geometric sequence is 0.0061

Step-by-step explanation:

The general form of geometric sequence is a, ar, ar²,ar³,.......

where,

a is the first term of the sequence.
r is the common ratio. Here, the common ratio r = 4.
The 8th term of the sequence is 100. Hence n = 8.

The formula to find the nth term of the geometric sequence is given by :

⇒ $n_{th} term = ar^{n-1}$

⇒ $8_{th}term = a\times4^{8-1}$

⇒ $100 = a \times 4^{7}$

⇒ $100 = a \times 16384$

⇒ $a = \frac{100}{16384}$

⇒ a = 0.0061

Therefore, the first term of the geometric sequence is 0.0061

Suppose the path of a baseball follows the path graphed by the quadratic function ƒ(d) = –0.6d2 + 5.4d + 0.8 where d is the hori

Vinil7 [7]

Answer:

Domain is all real numbers

Range is

$y\le 12.95$

Step-by-step explanation:

The given function is

$f(d)=-0.6d^2+5.4d+0.8$

This is a maximum quadratic function therefore the domain is all real numbers.

Let us complete the square to find the vertex.

$f(d)=-0.6(d^2-9d)+0.8$

$f(d)=-0.6(d^2+9d)+-0.6(\frac{9}{2})^2- -0.6(\frac{9}{2})^2+ 0.8$

$f(d)=-0.6(d-\frac{9}{2})^2+\frac{243}{20}+ 0.8$

$f(d)=-0.6(d-\frac{9}{2})^2+\frac{259}{20}$

Therefore the range is

$y\le \frac{259}{20}$

$y\le 12.95$

Write the explicit formula for the sequence {9,6,3,0,-3,...}.

pantera1 [17]

Hi
The formula starts with x=9. So the formula would be x-3, than you get a different number and you fill x with that number do this over and over and you will get to -3 or even lower
