Answer:

Probability of choosing a Diamond= 9/26

Choosing a card that is not a club is=19/26

Step-by-step explanation:

These are the answers because...

Step one Add up all of the rows. 5+9+7+5=26
Step two, To find the probability of diamonds we need to take the total number of all the rows which is 26. And the number of diamonds which is 9. Then put it into a fraction 9/26
Step three to find the probability of choosing a card that is not a club, we would have to add up all the rows except the clubs which is 19, then out it over the total number which is 26. So 19/26
Hope this helped Please comment below on how you think my answer is. I would appreciate it Brainly

Please help me!!!!!!!! Factor z2 – 3z – 18

Vladimir [108]

First, the factor pairs for 18 are:
1, 18
2, 9
3, 6

Since the middle term is -3, the two factors must be 3 apart. The only pair that is 3 values apart is 3, 6.
Since the middle value is negative, the larger number is negative. This means that the 6 is negative.
z = -6
z = 3

Set each equal to 0;
z = -6
z + 6 = 0

z = 3
z - 3 =0
So your factors are (z+6) and (z-3), or answer B.

What value of n makes the equation true? (2x^9y^n)(4x^2y^10)=8x^11y^20

Komok [63]

Hi there! The answer is n = 10.

$(2 {x}^{9} {y}^{n} )(4 {x}^{2} {y}^{10} ) = 8 {x}^{11} {y}^{20}$

As you see at the powers of x, we need to add the exponents of the power we when multiply them.
${x}^{9} \times {x}^{2} = {x}^{9 + 2} = x {}^{11}$

The powers of y work the same way.
${y}^{n} \times {y}^{10} = {y}^{n + 10} = {y}^{20}$

Hence, n = 10, since
${y}^{10 + 10} = {y}^{20}$
