Oh hello there help plz !

Find the common difference for the sequence shown 1/4,5/16,3/8

Vladimir79 [104]

<span>common difference for the sequence = 1/16

cause
1/4 = 4/16
and
3/8 = 6/16

so
4/16 + 1/16 = 5/16
5/16 + 1/16 = 6/16

Suppose a hypothesis test for a population mean is correctly conducted and the decision is made to not reject the null hypothesi

ArbitrLikvidat [17]

Answer: B) type II error

Step-by-step explanation: whenever hypothesis test is performed it is not possible to be 100% certain about the conclusion or decision made, hence their must be a level of confidence for the conclusion made.

The level of significance (α) usually takes the lower percentage of the area of distribution.

When you reject the null hypothesis instead of accepting it, you commit a type I error, the probability of committing this error is the level of significance (α).

When you accept the null hypothesis when you are suppose to reject it, you commit a type II error and the probability of committing this error is confidence level (β) which is (1- α)

For the graph, which are possible functions ƒ, g, and h?

lesya692 [45]

Answer:

The third option is correct

$\displaystyle h(x)=\left ( \frac{10}{3} \right )^x$

$\displaystyle g(x)=\left ( \frac{7}{4} \right )^x$

$\displaystyle f(x)=\left ( \frac{9}{8} \right )^x$

Step-by-step explanation:

Exponential function

The exponential function is usually expressed as

$f(x)=Cr^{kx}$

If both C and k are positive, then f is increasing in all of its domain. Same happens if both are negative. They all have one point in common: (0,C)

The graph shows three functions, all increasing and in all of them (given the options for the answer) have C=1 and k=1, so the equation for each one is

$f(x)=r^{x}$

When x=1, f(1)=r lets us know the value of r

From the graph we can see that the value of r is the greatest for h(x). The next value of r is that one for g(x). Finally, f(x) has the smallest r. That means that

$h(1)>g(1)>f(1)$

We only need to check the options to order h,g,f from greatest to lowest. Since (10/3)=3.3, (9/8)=1.12, (7/4)=1.75 then

h(x) must have $r=\frac{10}{3}$

g(x) must have $r=\frac{7}{4}$

f(x) must have $r=\frac{9}{8}$

So the third option is correct

$\displaystyle h(x)=\left ( \frac{10}{3} \right )^x$

$\displaystyle g(x)=\left ( \frac{7}{4} \right )^x$

$\displaystyle f(x)=\left ( \frac{9}{8} \right )^x$

A cone-shaped paper water cup has a height of 12 cm and a radius of 6 cm. If the cup is filled with water to one-third its hei

solniwko [45]

Answer is 150.72 cu.cm.
Let’s find the total cone volume first
Cone volume formula is 1/3 pi r^2 height
We know r = 6
We know height is 12
We will use 3.24 for pi
So
(1/3) (3.14) (6^2) (12) = 452.16
Now we want to find 1/3 of the volume so divide that by 3
Amount of water is 150.72 cu.cm.

In a parallelogram what can you say about the consecutive angle

Sav [38]

Answer:

Sum of two consecutive angle is always 180°

Step-by-step explanation:

In a parallelogram what we can you say about the consecutive angle is that they are supplementary to each other. By supplementary we mean that the sum of the two angles is always 180°
