<span>Simplifying
23 + 45 + -48 + 34x = 292
</span><span>
Combine like terms: 23 + 45 = 68
68 + -48 + 34x = 292

</span><span>Combine like terms: 68 + -48 = 20
20 + 34x = 292
</span>
<span>Solving
20 + 34x = 292
</span>
<span>Solving for variable 'x'.
</span>
<span>Move all terms containing x to the left, all other terms to the right
</span>
<span>Add '-20' to each side of the equation.
20 + -20 + 34x = 292 + -20
</span>
<span>Combine like terms: 20 + -20 = 0
0 + 34x = 292 + -20
34x = 292 + -20
</span>
<span>Combine like terms:
292 + -20 = 272 34x = 272
</span>
<span>Divide each side by '34'.
x = 8
</span>
Simplifying x = 8

Hope it helped : )

Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 8

Alina [70]

Answer:

Null hypothesis = H₀ = There food preferences among vole species are independent of one another.

Alternate hypothesis = H₁ = There is a relationship between voles and food preference.

Expected meadow vole/apple slices = 29.983051

Expected common vole/apple slices = 28.016949

Expected meadow vole/peanut butter-oatmeal = 31.016949

Expected common vole/peanut butter-oatmeal = 28.983051

Chi-square value = χ² = 2.154239

Degree of freedom = 1

Critical value = 3.841

χ² < Critical value

We failed to reject H₀

We do not have significant evidence at the given significance level to show that there is a relationship between voles and food preference.

Step-by-step explanation:

He frequently traps the moles and has noticed what appears to be a preference for a peanut butter-oatmeal mixture by the meadow voles vs apple slices are usually used in traps, where the common voles seem to prefer the apple slices.

So he conducted a study where he used a peanut butter-oatmeal mixture in half the traps and the normal apple slices in his remaining traps to see if there was a food preference between the two different voles.

Null hypothesis = H₀ = There food preferences among vole species are independent of one another.

Alternate hypothesis = H₁ = There is a relationship between voles and food preference.

Data collected by Dr. Pagels:

                                              meadow voles     common voles      Row Total

apple slices                                     26                          32                      58

peanut butter-oatmeal                   35                          25                     60

Column Total                                   61                          57                     118

Where 118 is the grand total.

The expected number is given by

Expected = (row total)×(column total)/grand total

Expected meadow vole/apple slices = 58×61/118

Expected meadow vole/apple slices = 29.983051

Expected common vole/apple slices = 58×57/118

Expected common vole/apple slices = 28.016949

Expected meadow vole/peanut butter-oatmeal = 60×61/118

Expected meadow vole/peanut butter-oatmeal = 31.016949

Expected common vole/peanut butter-oatmeal = 60×57/118

Expected common vole/peanut butter-oatmeal = 28.983051

The chi-square statistic value is given by

χ² = Σ(Observed - Expected)²/Expected

χ² = (26 - 29.983051)²/29.983051 + (32 - 28.016949)²/28.016949 + (35 - 31.016949)²/31.016949 + (25 - 28.983051)²/28.983051

χ² = 2.154239

The degrees of freedom is given by

DoF = (row - 1)×(col - 1)

For the given case, we have 2 rows and 2 columns

DoF = (2 - 1)×(2 - 1)

DoF = 1

The given level of significance = 0.05

The critical value from the chi-square table at α = 0.05 and DoF = 1 is found to be

Critical value = 3.841

Conclusion:

Reject H₀ If χ² > Critical value

We reject the Null hypothesis If the calculated chi-square value is more than the critical value.

For the given case,

χ² < Critical value

We failed to reject H₀

We do not have significant evidence at the given significance level to show that there is a relationship between voles and food preference.

What are the the transformations of h(x)= -f(x+4)-12
katrin [286]

given f)x) then

- f(x) represents a reflection in the x-axis

f(x + 4 ) represents a shift of 4 units horizontally to the left

f(x) + 12 represents a vertical shift of 12 units down

thus h(x) = f(x + 4 ) - 12

is the graph of f(x), moved 4 units left, 12 units down and reflected in the x- axis
