Answer:

Five times a number" is written as 5x. This is because the number itself is unknown, so we use a variable.

"Difference" means subtraction; thus "The difference of five times a number and 9" would be 5x-9.

Solve for x in the picture please

Nutka1998 [239]

Answer: $x=1$

Step-by-step explanation:

In order to find the value of "x", it is important to remember that:

$Tangent\ chord\ angle=\frac{1}{2}(Intercepted\ arc)$

We can identify in the figure that:

$Tangent\ chord\ angle=(43x)\°\\\\Intercepted\ arc=AB$

Then:

$43x=\frac{1}{2}AB$

Solving for AB:

$2(43x)=AB\\\\AB=86x$

Now, since there are 360° in a circle, we know that:

$AB+(272x+2)=360$

Then we can substitute $AB=86x$ into $AB+(272x+2)=360\°$ and solve for "x". This is:

$(86x)+(272x+2)=360\\\\358x=360-2\\\\x=\frac{358}{358}\\\\x=1$

A researcher is testing a hypothesis of a single mean. The critical z value for a = .05 and a two‑tailed test is +1.96. The obse

grandymaker [24]

Answer:

The decision made by the researcher based on this information is to reject the null hypothesis.

Step-by-step explanation:

Two-tailed hypothesis test:

Critical value: $z_c$

Test statistic: z

If $|z| < |z_c|$ , we do not reject the null hypothesis.

If $|z| > |z_c|$ , we reject the null hypothesis.

In this question:

$z_c = 1.96, z = -2.05, |z| = 2.05$

Since $|z| > |z_c|$ , we reject the null hypothesis.

The decision made by the researcher based on this information is to reject the null hypothesis.
