Answer:

$\cfrac{1}{64}$

Step-by-step explanation:

$\cfrac{1}{\:4}\times \cfrac{1}{4}\times \cfrac{1}{4}$

_____________________

$\cfrac{1\times \:1\times \:1}{4\times \:4\times \:4}$

Multiply: 1 * 1 * 1 = 1

$\cfrac{1}{4\times \:4\times \:4}$

Multiply: 4 * 4* 4= 64

$\cfrac{1}{64}$

tigry1 [53]

Answer:

$f_X(k)=\binom{4}{k}0.003^k0.997^{4-k}$

Step-by-step explanation:

Recall that a <em>probability mass function</em> defined on a discrete random variable X is just a function that gives the probability that the random variable equals a certain value k

$f_X(k)=P(X=k)$

In this case we have the event

“The computer will ask for a roll to the left when a roll to the right is appropriate” with a probability of 0.003.

Then we have 2 possible events, either the computer is right or not.

Since we have 4 computers in parallel, the situation could be modeled with a binomial distribution and the probability mass function

$f_X(k)=\binom{4}{k}0.003^k0.997^{4-k}$

This gives the probability that k computers are wrong at the same time.

What is 4/9 - 2/15 in simplest form

Georgia [21]

To subtract 2 fraction we have to make common denominator.
$\frac{4}{9} - \frac{2}{15} = \frac{4*5}{9*5}- \frac{2*3}{15*3} = \frac{20}{45}- \frac{6}{45} = \frac{20-6}{45}= \frac{14}{45}$ - its the simpest form

Which of the following quadratic equations has no real solutions?

Virty [35]

Answer:

C. 3x^2 + 2x + 1

Step-by-step explanation:

A. 12^2 - (4*3*12) = 0 (there's one solution.)

B. (-3)^2 - (4*3*-18) = 255 (there're 2 real solutions.)

D. 3^2 - (4*0*-3) = 9 (there're 2 real solutions.)

C. 2^2 - (4*3*1) = -18 ✅✅

if b^2 - 4ac = negative then we can say that there isn't any real solution for the equation.

amanda like to knit hats and mittens for friends and family.last fall, she knitted 2 hats and 4 pairs of mittens, which which to

sdas [7]

Answer:

We now know that a hat takes 6 hours to knit and a pair of mittens take 9 hours to knit.

In total, it takes 15 hours to knit a hat and a pair of mittens.

Step-by-step explanation:

We can construct a system of equations to model this:

Let x represent hats and y represent mittens.

1. 2x + 4y = 48

2. 2x + 3y = 39 We can solve this system by elimination.

Mutliply equation 2, fully, by -1 to eliminate the x's.

2x + 4y = 48

-2x - 3y = -39 Now add the equations together.

y = 9 We can now substitute this into equation 1, or 2, to get the x value.

1. 2x + 4y = 48

2x + 4(9) = 48

2x + 36 = 48 Subtract 36 from both sides.

2x = 12 Divide both sides by 2.

x = 6

x represented the hats, and y represented the mittens, so we now know that a hat takes 6 hours to knit and a pair of mittens take 9 hours to knit.

In total, it takes 15 hours to knit a hat and a pair of mittens.
