Answer:

x≤3

Step-by-step explanation:

Since you can't get any more than 3 flash drives, the inequality is (making x=the number of USB flash drives you can buy):

x≤3

Determine the sum: (14abc2 + 12a2b + 16b2c) + (−3abc2 + 2b2c).

Alenkinab [10]

The answer is 11abc^2 + 12a^2b + 18b^2c because:
14abc^2-3abc^2 is 11abc^2
12a^2b + 0 = 12a^2b
16b^2c +2b^2c = 18b^c

Answer:

$\frac{1}{16}$ $\frac{10}{9}$

Step-by-step explanation:

a reciprocal is a number that when multiplied by a given number gives 1 as product.

16 * x = 1

x = 1/16

9/10 * x = 1

x = 10/9

Answer:

0.1505 = 15.05% probability that the hockey team wins 6 games in November

Step-by-step explanation:

For each game, there are only two possible outcomes. Either the team wins, or it does not. The probability of winning a game is independent of winning other games. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

The probability that a certain hockey team will win any given game is 0.3723

So $p = 0.3723$

12 games in November

So $n = 12$

What is the probability that the hockey team wins 6 games in November?

This is $P(X = 6)$

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 6) = C_{12,6}.(0.3723)^{6}.(1-0.3723)^{6} = 0.1505$

0.1505 = 15.05% probability that the hockey team wins 6 games in November

Urgent due for tommorow . will mark brainliest and get 50 pts<br>plz show workings

Vilka [71]

Answer:

Step-by-step explanation:

Sec B

1) 5p⁻³ = 8*5⁻²

p⁻³ = 2³*5⁻²/5

p⁻³ =2³*5⁻³ { 1/a^m = a^-m}

p⁻³ = 5⁻³ /2⁻³ {a^m = 1/a^-m}

p⁻³ = (5/2)⁻³

p= 5/2

2) 4x² = 81

x² = 81/4

x² = 9² /2²

x² =(9/2)²

x = 9/2

3) 9^x/3 =81

9^x/3 = 9^2

Comparing the powers, x/3 = 2

x = 2*3 =6

x = 6

Juliette [100K]

Answer:

The test statistic is $t = 2.79$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 59.3$

The sample size is $n = 79$

The sample mean is $\= x = 62.4$

The standard deviation is $\sigma = 9.86$

Generally the test statistics is mathematically represented as

$t = \frac{\= x - \mu }{ \frac{ \sigma}{ \sqrt{n} } }$

substituting values

$t = \frac{ 62.2 - 59.3 }{ \frac{ 9.86}{ \sqrt{ 79} } }$

$t = 2.79$
