75% is the same as .75

So to make it into its simplest form convert it to a fraction

So the answer is 3/4

Question 1 1.1 Given the quadratic number pattern: 5; 10; 17; 26;.. 1.1.1 Write down the next TWO terms of the pattern. 1.1.2 D
vitfil [10]

The next two terms of the sequence based on the information given is 37 and 50.

<h3>How to illustrate the sequence?</h3>

It should be noted that from the information given, the numbers illustrated are 5, 10, 17, and 26.

In this case, there is an addition of 2 to the previous difference.

Therefore, 26 - 17 = 9.

The next number will be:

= 26 + 9 + 2 =37

The following number will be:

= 37 + 11 + 2

= 50

The valve was tested on 270 engines and the mean pressure was 6.6 lbs/square inch. Assume the variance is known to be 0.49. If t
BlackZzzverrR [31]

Answer:

z=\frac{6.6-6.5}{\frac{0.7}{\sqrt{270}}}=2.347      

The p value for this case would be given by"

p_v =2*P(z>2.347)=0.0189  

For this case since the p value is higher than the significance level we don't have enough evidence to conclude that the true mean is significantly different from 6.5 lbs/square inch at 10% of significance. So then there is not enough evidence to conclude that the valve does not perform to the specifications

Step-by-step explanation:

Information given

\bar X=6.6 represent the sample mean

s=\sqrt{0.49}= 0.7 represent the population deviation

n=270 sample size      

\mu_o =6.5 represent the value that we want to test    

\alpha=0.1 represent the significance level

z would represent the statistic

p_v represent the p value for the test

Hypothesis to verify

We want to verify if the true mean for this case is equal to 6.5 lbs/square inch or not , the system of hypothesis would be:      

Null hypothesis:\mu= 6.5      

Alternative hypothesis:\mu \neq 6.5      

The statistic for this case is given by:

t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}} (1)      

And replacing we got:

z=\frac{6.6-6.5}{\frac{0.7}{\sqrt{270}}}=2.347      

The p value for this case would be given by"

p_v =2*P(z>2.347)=0.0189  

For this case since the p value is higher than the significance level we don't have enough evidence to conclude that the true mean is significantly different from 6.5 lbs/square inch at 10% of significance. So then there is not enough evidence to conclude that the valve does not perform to the specifications

Probability of landing on even # on a spinner; probability of rolling an odd # on a die
KonstantinChe [14]

Answer:

Spinner: 50%

Die: 50%

Step-by-step explanation:

Well for the spinner it depends on the amount of numbers it has,

in this case we’ll use 6.

So The probability of landing on the even numbers in a 6 numbered spinner.

2, 4, 6

3/6

50%

Your average die has 6 sides so the odd numbers are,

1, 3, 5

3/6

50%

What is the expected value?
DochEvi [55]

Answer:

2.1

Step-by-step explanation:

The expected value of a probability is given by the formula:

E(x) = Σxp(x)

Therefore from the table showing the winnings of a game, the expected value of the probability distribution is:

E(x) = Σxp(x) = (0 * 0.5) + (2 * 0.2) + (4 * 0.15) + (6 * 0.1) + (10 * 0.05)

E(x) = 0 + 0.4 + 0.6 + 0.6 + 0.5 = 2.1

Hence we can conclude that the expected value of the winnings of the game is 2.1.
