How many ways can you choose 4 cookies from a cookie jar containing 25 cookies of all the same type?
andre [41]

Answer:

Only one.

Step-by-step explanation:

Given that there are 25 cookie of the same type in a cookie jar.

We have to select 4 cookies from these 25.

Since they are all the same type, they are identical.

The question is

How many ways can you choose 4 cookies from a cookie jar containing 25 cookies of all the same type?

There is no difference if we take any four cookies from these 25.

Hence no of different ways = 1

Only one is the answer.

A chip used in the production of particleboard (Question 4) has a 15% chance of containing excessive bark. What is the probabili
salantis [7]

Answer:

0.2

Step-by-step explanation:

Given that:

P(particleboard with excessive bark) = 0.15

The P(that particleboard do not have excessive bark) = 1 - 0.15

i.e the population proportion number of success p = 0.85

The sample size (n) is given to be = 1000

To find the P(X ≥ 860)

Since the sample size is large, we will apply the normal approximation of binomial distribution to treat this question.

The population mean \mu = n \times p

\mu = 1000 \times 0.85

\mu =850

The population standard deviation \sigma = \sqrt{n*p(1-p)

\sigma = \sqrt{1000*0.85*(1-0.85)}

\sigma = \sqrt{1000*0.85*(0.15)}

\sigma = \sqrt{127.5}

\sigma = 11.2916

Let X be the random variable which obeys a normal distribution;

Then;

P(X \ge 860) = P(Z\ge \dfrac{x- \mu}{\sigma})

P(X \ge 860) = P(Z\ge \dfrac{860- 850}{11.2916})

P(X \ge 860) = P(Z\ge \dfrac{10}{11.2916})

P(X ≥ 860) = P(Z ≥ 0.8856)

P(X ≥ 860) = 1 - P(Z ≤ 0.8856)

From  z table

P(X ≥ 860) = 1 - 0.8122

P(X ≥ 860) = 0.1878

P(X ≥ 860) \simeq 0.2

Thus, the probability of having more than 860 bark-free chips in a batch of 1,000 = 0.2

X - y = 3<br> x + 2y = -6<br><br><br> Giving out brainliest<br> SHOW ALL OF YOUR WORK☺
taurus [48]
x-y=3
x+2y=-6

Subtract both equations to isolate and solve for y.

(x-x)+(-y-2y)=3-(-6)
0+-3y=9
y=-3

Now, solve for x in either equation by plugging in the y value.
I will choose the simpler first equation: x-y=3

x+3=3
x=0 ; y=-3
