I don't know. This seems tricky. But I do know that the probability would be 1 divided by the probability. So A and D is Incorrect. Theres never really a 50-50 chance with Locker doors so I'm gonna go with C.

I'm not guaranteed this is the answer. But I do Hope it helps. =)

The problem is complicated since there are a lot of variables to consider, however I do know that it's probably D.

We know that the first digit is more than 5. And the second we are guessing the probability for which is if it will be more than 5.

Now I can't say I do know the answer or how to solve it, but I know it's definitely not 1/2 or 1/3. I wouldn't say it's B. either because you cannot include 5, which if it was true for that equation then we're saying including the first digit we have 5 chances, however it only goes up to 9 because we don't count zero.

Hope this helped in some way.

What values of k will make the line containing points (k,3) and (-2,1) parallel to the line through (5, K) and (1,0)

rjkz [21]

Answer:

k = -4 or 2

Step-by-step explanation:

For the lines to be parallel, the lines would need to be the same slope. This means to find the slope of each we would take the difference of the rise over the run.

$\frac{1-3}{-2-k}=\frac{-2}{-2-k}$

and

$\frac{0-k}{1-5}=\frac{-k}{-4}$

To find K, set them equal.

$\frac{-2}{-2-k} = \frac{-k}{-4}\\-k(-2-k) = -2*-4\\2k+k^2=8\\k^2+2k-8=0$

Factor the quadratic and solve for K.

$(k+4)(k-2)=0$

k+4=0 so k=-4

k-2=0 so k=2

Can someone help me with this problem?

pashok25 [27]

No, it is not a solution.

Let's plug 5 into the equation where p is.

10(5) - 2 > 97

50 - 2 > 97

48 > 97

This is false, 48 is less than 97.

A gardener is planting two types of trees:

denpristay [2]

It takes 12 years for both trees to be of same height

Solution:

Assume the year that it would take to these trees have the same height is : x (years)

Type A is 7 feet tall and grows at a rate of 23 inches per year:

Convert 7 feet to inches

We know that,

1 foot = 12 inch

7 feet = 12 x 7 inch = 84 inch

Thus, type A is 84 inches tall and grows at a rate of 23 inches per year

We can frame a equation as:

Type A = 84 + 23(number of years)

Type A = 84 + 23x ---------- eqn 1

Type B is 5 feet tall and grows at a rate of 25 inches per year

Convert 5 feet to inches

5 feet = 5 x 12 inches = 60 inches

Thus, type B is 60 inches tall and grows at a rate of 25 inches per year

We can frame a equation as:

Type B = 60 + 25(number of years)

Type B = 60 + 25x --------- eqn 2

For both the trees to be of same height, eqn 1 must be equal to eqn 2

84 + 23x = 60 + 25x

25x - 23x = 84 - 60

2x = 24

x = 12

Thus it takes 12 years for both trees to be of same height

What is the product?

zepelin [54]

Answer:

Option D

Step-by-step explanation:

We need the product of:

(-3s + 2t)*(4s - t)

We can use the distributive property:

(a + b)*(c + d) = a*c +b*c + a*d + b*d

Applying to our case:

(-3s + 2t)*(4s - t) = (-3s)*4s + (-3s)*(-t) + 2t*4s + (2t)*(-t)

(-3s + 2t)*(4s - t) = -12(s^2) + 3st + 8ts - 2(t^2)

(-3s + 2t)*(4s - t) = -12(s^2) + 11ts - 2(t^2)

So, the correct is option D negative 12 s squared + 11 s t minus 2 t squared
