Students in the fifth-grade class bought 30 yards of fabric to make pennants for a pep rally. Each pennant requires 1/3 yard of

fabric. If the students have already made 35 pennants from the fabric, how many more pennants can they still make? *

PLZ ANSWER ASAP WILL GIVE 50PTS if u explain and mark brainliest!!!!!!!

Vinil7 [7]

Answer:

Step-by-step explanation:

1.

$\frac{5q+5p}{2} = 3+4p\\5q+5p = 6+8p \\5q = 6 +3p \\q = \frac{6+3p}{5} ( a=3,b=6,c=5)$

2. q-p = 3p +5

q = 4p+5

4p = q-5

p = (q-5)/4

3. y = 2a -b $x^{2}$

$bx^{2} = 2a - y \\\\x^{2} = \frac{2a - y}{b} \\x = \sqrt{\frac{2a-y}{b}}$

The arrivals of clients at a service firm in Santa Clara is a random variable from Poisson distribution with rate 2 arrivals per

ICE Princess25 [194]

Answer:

1.76% probability that in one hour more than 5 clients arrive

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given time interval.

The arrivals of clients at a service firm in Santa Clara is a random variable from Poisson distribution with rate 2 arrivals per hour.

This means that $\mu = 2$

What is the probability that in one hour more than 5 clients arrive

Either 5 or less clients arrive, or more than 5 do. The sum of the probabilities of these events is decimal 1. So

$P(X \leq 5) + P(X > 5) = 1$

We want P(X > 5). So

$P(X > 5) = 1 - P(X \leq 5)$

In which

$P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)$

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 0) = \frac{e^{-2}*2^{0}}{(0)!} = 0.1353$

$P(X = 1) = \frac{e^{-2}*2^{1}}{(1)!} = 0.2707$

$P(X = 2) = \frac{e^{-2}*2^{2}}{(2)!} = 0.2707$

$P(X = 3) = \frac{e^{-2}*2^{3}}{(3)!} = 0.1804$

$P(X = 4) = \frac{e^{-2}*2^{4}}{(4)!} = 0.0902$

$P(X = 5) = \frac{e^{-2}*2^{5}}{(5)!} = 0.0361$

$P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0.1353 + 0.2702 + 0.2702 + 0.1804 + 0.0902 + 0.0361 = 0.9824$

$P(X > 5) = 1 - P(X \leq 5) = 1 - 0.9824 = 0.0176$

1.76% probability that in one hour more than 5 clients arrive

3,000 is 10 times as much as

nalin [4]

3,000 is 10 times as much as

3000 = 10 times of what number

We need to find 10 times what number gives us 3000

Let the unknown number be x

3000 = 10 times x

3000 = 10x

To solve for x, we divide by 10 on both sides

$\frac{3000}{10}=\frac{10x}{10}$

300 = x

So, the unknown number is 300

3000 = 10 times 300

3000 is 10 times as much as 300
