Z=kx, 30=8k, so k=30/8=15/4 and z=15x/4, so when x=4, z=15.

Answer:

Yes she made an error. Explanation is below.

Step-by-step explanation:

Let the sample space for a six sided number cube be S

$n(S) = \{1,2,3,4,5,6\}\\n(S) = 6$

Let the event of a number getting greater than two be B

$n(B) = \{3,4,5,6\}\\n(B) = 4$

To find:

the probability of complement of B that is

p(~B) = ?

Solution"

First we need to solve probability for number getting greater than two

$p(B) = \frac{n(B)}{n(S)}$

Now substituting the values we get

$p(B) = \frac{4}{6}$

$p(B) = \frac{2}{3}$

but we need complement of B so

$p(\textrm{complement of B)} = 1 - p(B)\\p(\~B) = 1 - p(B)\\p(\~B) = 1 - \frac{2}{3}\\ =\frac{1}{3} \\$

P(complement of rolling a number greater than two) = $\frac{1}{3}$

Answer:

(5)2

Step-by-step explanation:

As we know that the equation of circle with center at (h,k) ad radius r is given as-

(x−h)

+(y−k)

Given that the centre of circle is (1,4) and radius is 5.

Therefore the equation of circle is-

(x−1)

+(y−4)

=(5)

Ber [7]

Answer:

I believe the answer is 7/20 or 35%.

Step-by-step explanation:

I first started by subtracting the coins that we already know from the total, and I get 7. I put that in fraction form which is, 7/20 and I turned it into percent form which is 35%. I hope one of these answers helps.
