Answer:

$\frac{16}{25}$

Step-by-step explanation:

We have four fractions and are asked to find the next one in the sequence.

So we see that 8/25 and 10/25 are together, which then follows up with 12/25 and 14/25.

Do we see a pattern? Yes indeed, the numerator is going up two values of every sequence, therefore we need to add 2/25 to 14/25 to find the next fraction.

$\frac{14}{25} + \frac{2}{25}$

$\frac{16}{25}$

Which is the graph of f (x) = 4 (1/2) Superscript x?

miss Akunina [59]

Answer:

Option (2) is correct graph.

Step-by-step explanation:

Given:

The function to graph is given as:

$f(x)=4(\frac{1}{2})^x$

Now, the above function is an exponential function of the form $f(x)=ka^x$

Where, 'k' and 'a' are constants.

The range of an exponential function is always greater than 0.

The domain is all real numbers.

Now, for graphing it, we need to find some points on it and its end behaviour.

Now, for x = 0, the function value is given as:

$f(0)=4(\frac{1}{2})^0=4$

So, (0, 4) is a point on the graph.

Now, for x = 1, the function value is given as:

$f(1)=4(\frac{1}{2})^1=4\times\frac{1}{2}=2$

So, (1, 2) is another point on the graph.

Now, for x = 2, the function value is given as:

$f(2)=4(\frac{1}{2})^2=4\times\frac{1}{4}=1$

So, (2, 1) is another point on the graph.

Now, as 'x' tends to ∞, the function value tends to:

$f(x\to\infty)=4\cdot\frac{1}{2}^{\infty}=\frac{4}{\infty}=0$

So, as

$x\to\infty,f(x)\to0\\\\x\to-\infty,f(x)\to\infty$

Now, from among all the options, only option (2) fulfills all the conditions given above.

So, option (2) is correct graph.

Can anyone help me with question number 3

ira [324]

The answer is: There are 595 calories in a banana split

To find this we first need to set up our equation:

$80= \frac{1}{7}x-5$ , where x= calories in a banana split

$85= \frac{1}{7}x$ ----------------Add 5 to both sides

595=x-------------------Multiply 7 to both sides to get rid of the fraction

So, there are 595 calories in a banana split

Hope this helps! :)

Chloe has 20 unit cubes how many different rectangular prisms can she build with the cubes

Makovka662 [10]

Cubes are 3D so what 3 numbers multiply to 20
20×1×1
10×2×1
5×4×1
5×2×2
so 4 different shaped cubes

∠E and ∠F are vertical angles with m∠E=8x+8 and m∠F=2x+38 . What is the value of x?

givi [52]

As they are vertical angles, their magnitude will be equal.
8x+8 = 2x+38
8x-2x = 38-8
6x = 30
x = 5

So, Your Final Answer would be 5

Hope this helps!

(d) estimate p(x < 1.5), i.e., the proportion of all thickness values less than 1.5. [hint: if you knew the values of μ and σ

Elan Coil [88]

This question's solution is based on two context. First off, the probability of any events or occurrence cannot be greater than 1. If the question demands finding the probability that the proportion of all thickness (X) is less than 1.5 given the available data (mu and rho) then that would practically be impossible. It would only be feasible to ask, "if it were less than 1" My point is, suppose X is 1.3 which is actually less than 1.5, then we have a contradiction because our probability of occurrence or non-occurrence cannot be greater than 1.On the other hand suppose X is 0.2, then it will be pretty easy to input the formula to get valuable results.
