Answer:

This function would be even.

Step-by-step explanation:

You can tell a function is even if you plug in -x for x and then simplify and it is the same function. This is the case below.

y = 2x^4 + 2x^2 ----> Plug in -x

y = 2(-x)^4 + 2(-x)^2 ----> Simplify

y = 2x^4 + 2x^2

You'll notice the simplified version is exactly the same as the original, which makes it odd.

2/11 + (4/11 + 1/11) = (2/11 + 4/11) + 1/11 Solve with step

aniked [119]

Answer:

$\frac{7}{11} = \frac{7}{11}$

Step-by-step explanation:

$\frac{2}{11} + ( \frac{4}{11} + \frac{1}{11} ) = ( \frac{2}{11} + \frac{4}{11} ) + \frac{1}{11} \\ \frac{2}{11} + \frac{5}{11} = \frac{6}{11} + \frac{1}{11} \\ \frac{7}{11} = \frac{7}{11} \\$

Deanna collected data on the favorite sports of the students of two grades. The table shows the relative frequencies of rows for

Blababa [14]

Answer:

In Grade 8, 22% of students liked volleyball.

Step-by-step explanation:

Given:

The table representing the relative frequencies of different sports in different grades among the students.

Swimming Running Volleyball Row totals

Grade 8 0.14 0.18 0.22 0.54

Grade 9 0.17 0.24 0.05 0.46

Column totals 0.31 0.42 0.27 1

Relative frequency gives the ratio of the number of quantities of a particular kind and the total number of quantities.

$\textrm{Relative frequency}=\frac{\textrm{Number of students in a particular sport}}{\textrm{Total students}}$

From the above table, we can conclude the following points:

Grade 8:

14% liked swimming, 18% liked running and 22% liked volleyball. So, a total of 54% students liked playing sports.

Grade 9:

17% liked swimming, 24% liked running and 5% liked volleyball. So, a total of 46% students liked playing sports.

Combining students of grade 8 and 9:

31% liked swimming, 42% liked running and 27% liked volleyball.

From all the options available, we observe that, third option is only correct.

In Grade 8, 22% of students liked volleyball.

Plz tell answer for 33 pnts but dont scam

Alchen [17]

Answer:

(i)

Given

∠BED = ∠BAC

Also we see that

∠ABC = ∠DBE as refer to same angle

Since two angles of triangles are congruent, the triangles are similar by AA similarity postulate

ΔABC ~ ΔEBD

(ii)

In similar figures corresponding parts have same ratio. Use ratios to find the value of x:

AB/EB = AC/ED
12/8 = x / 4
x = 4*12/8
x = 6 cm
