Name 3 decimals whose product is about 40

Write a function in any form that would match the graph shown below.

BabaBlast [244]

Answer:

y = 2(x +1)(x -4)

Step-by-step explanation:

The intercepts are at grid points, so it is easiest to make use of those. For an x-intercept of "a", one of the factors of the function is (x -a). Here, the x-intercepts are -1 and +4, so the function has factors (x +1)(x -4).

When x=0, the product of these factors is (1)(-4) = -4, so there is a vertical scale factor of 2 to make the y-intercept be -8. The function can be written as ...

y = 2(x +1)(x -4)

A restaurant has 4 appetizers, 5 entrees and 2 desserts. How many different meal combinations could you order?

vovangra [49]

Step-by-step explanation:

1.) Firstly, you need to count out how many things there are. 4 app, 5 entrees, 2 desserts. This makes 11 different things

2.) for 11 numbers there can be 9 ways for each number for 1st nine places since 0 can't be the fist figure and next two are reciprocated from 10 numbers. Therefore 10!/2!

3.)So 99 combinations have 10!/2! Permutations hence total ways are 99*10!/2!

A machine in the student lounge dispenses coffee. The average cup of coffee is supposed to contain 7.0 ounces. A random sample o

Elenna [48]

Answer:

$t=\frac{7.4-7}{\frac{0.7}{\sqrt{7}}}=1.512$

The degrees of freedom are

$df=n-1=7-1=6$

And the p value for this case is:

$p_v =2*P(t_{(6)}>1.512)=0.181$

The p value is a higher value and using a significance levels of 5% or 10% we see that the p value is higher than the significance level and then we FAIL to reject the null hypothesis and we don't have enough evidence to conclude that the true mean is different from 7 ounces.

Step-by-step explanation:

Information provided

$\bar X=7.4$ represent the sample mean

$s=0.7$ represent the sample standard deviation

$n=7$ sample size

$\mu_o 7$ represent the value to verify

t would represent the statistic

$p_v$ represent the p value

System of hypothesis

We want to verify if the average amount of coffee per cup is different from 7 ounces, the system of hypothesis would be:

Null hypothesis: $\mu = 7$

Alternative hypothesis: $\mu \neq 7$

The statistic is given by:

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

Replacing the info given we got:

$t=\frac{7.4-7}{\frac{0.7}{\sqrt{7}}}=1.512$

The degrees of freedom are

$df=n-1=7-1=6$

And the p value for this case is:

$p_v =2*P(t_{(6)}>1.512)=0.181$

The p value is a higher value and using a significance levels of 5% or 10% we see that the p value is higher than the significance level and then we FAIL to reject the null hypothesis and we don't have enough evidence to conclude that the true mean is different from 7 ounces.
