Write the standard form equation of the circle( 7,-5)

Select from the drop-down menu to correctly complete the statement.

Usimov [2.4K]

The true statement is that: if you cannot get from one term to the next by adding or multiplying by a constant value, the sequence is neither arithmetic nor geometric

<h3>How to determine the true statement</h3>

A progression can either be arithmetic, geometric or neither.

When the progression has a common difference (gotten by addition), then the progression is arithmetic
When the progression has a common ratio (gotten by multiplication), then the progression is geometric

If the above are not true, then the sequence is neither arithmetic nor geometric

A manufacturing company produces valves in various sizes and shapes. One particular valve plate is supposed to have a tensile st

maxonik [38]

Answer:

$z=\frac{5.0611-5}{\frac{0.2803}{\sqrt{42}}}=1.413$

$p_v =2*P(z>1.413)=0.158$

If we compare the p value and the significance level given $\alpha=0.1$ we see that $p_v>\alpha$ so we can conclude that we have enough evidence to fail reject the null hypothesis, so we can't conclude that the average tensile strength is different from 5lbs/mm at 10% of signficance

Step-by-step explanation:

Data given and notation

$\bar X=5.0611$ represent the sample mean

$\sigma=0.2803$ represent the population standard deviation for the sample

$n=42$ sample size

$\mu_o =5$ represent the value that we want to test

$\alpha=0.1$ represent the significance level for the hypothesis test.

t would represent the statistic (variable of interest)

$p_v$ represent the p value for the test (variable of interest)

State the null and alternative hypotheses.

We need to conduct a hypothesis in order to check if the true mean is different from 5, the system of hypothesis would be:

Null hypothesis: $\mu = 5$

Alternative hypothesis: $\mu \neq 5$

If we analyze the size for the sample is > 30 but and we know the population deviation so is better apply a z test to compare the actual mean to the reference value, and the statistic is given by:

$z=\frac{\bar X-\mu_o}{\frac{\sigma}{\sqrt{n}}}$ (1)

z-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".

Calculate the statistic

We can replace in formula (1) the info given like this:

$z=\frac{5.0611-5}{\frac{0.2803}{\sqrt{42}}}=1.413$

P-value

Since is a two sided test the p value would be:

$p_v =2*P(z>1.413)=0.158$

Conclusion

If we compare the p value and the significance level given $\alpha=0.1$ we see that $p_v>\alpha$ so we can conclude that we have enough evidence to fail reject the null hypothesis, so we can't conclude that the average tensile strength is different from 5lbs/mm at 10% of signficance

If 4x-3<32, Which of the following are solutions: 26/3, 9.1, 20, or -6?

ValentinkaMS [17]

The answer is :
$4x - 3 < 32 \\ 4 x < 32 + 3 \\ 4 x < 35 \\ x < \frac{35}{4} \\$
$x < 8.75$
and the only number among the choices that is less than 8.75 is -6
hope it's true

Identify the slope of the line for the equation y = 10x + 3.

Iteru [2.4K]

Answer:324

Step-by-step explanation:

int i = 42.7; /* konwersja z double do int */

float f = i; /* konwersja z int do float */

double d = f; /* konwersja z float do double */

unsigned u = i; /* konwersja z int do unsigned int */

f = 4.2; /* konwersja z double do float */

i = d; /* konwersja z double do int */

char *str = "foo"; /* konwersja z const char* do char* [1] */

const char *cstr = str; /* konwersja z char* do const char* */

void *ptr = str; /* konwersja z char* do void* */
