Based on the graph, the slope of the line is -1/2 because the slope is negative, as it is going down 1 unit and then 2 units to the left.

The y-intercept(b), where x = 0, is -1

So your equation is:

y ? -1/2x - 1

The shaded area is above the line, which means that y is greater than "-1/2x - 1"

The inequality is:

y ≥ -1/2x - 1

The answer is A

First, we are going to find if the function is odd or even. Remember that we can determine if a function is odd of even from its graph by looking at its ends; if both ends go to the same the direction, the function is even. If both ends go to opposite directions, the function is odd. At both ends, the graph of our function go towards the same direction, minus infinity, so we can conclude that our function is even.

Next, we are going to find the possible degree of our function. Remember that the possible degree of a function is the number of x-intercepts.
We can infer from our graph that the function intercepts the x-axis at least 6 times.

We can conclude that the correct answer is: even degrees of 6 or greater.

slava [35]

Answer:

alternative hypothesis : H₁ :

Recent Gasoline surveys felt that gasoline price in Texas was significantly lower than the national average

Alternative Hypothesis : H₁: μ < $1.298 a gallon

Step-by-step explanation:

Explanation:-

Given A recent gasoline survey said that the national average price of gasoline was $1.298 a gallon

Population average μ= $1.298 a gallon

sample size 'n' = 37

Sample mean (x⁻) = $1.192 a gallon

Sample standard deviation 'S' = $0.0436

Null hypothesis :H₀ : μ = $1.298 a gallon

Alternative Hypothesis : μ < $1.298 a gallon

Degrees of freedom : ν = n-1= 37-1=36

t₀.₀₂₅ = 1.688

Test statistic

$t = \frac{x^{-}-mean }{\frac{S}{\sqrt{n} } }$

$t = \frac{1.192-1.298 }{\frac{0.0436}{\sqrt{37} } }$

t = -14.8044

|t| = |-14.8044| > 1.688

Null hypothesis is rejected

Alternative hypothesis is accepted

Recent Gasoline surveys felt that gasoline price in Texas was significantly lower than the national average

Triangle M R N. Angle N is 98 degrees. Side N M extends to form exterior angle with a measure of 109 degrees.

Scilla [17]

Answer:

16 degrees

Step-by-step explanation:

The question is

Find the measure of angle R

we know that

An exterior angle of a triangle is equal to the sum of the opposite interior angles

In this problem

$m\angle N+m\angle R=109^o$

we have

$m\angle N=93^o$

substitute

$93^o+m\angle R=109^o$

$m\angle R=109^o-93^o=16^o$

How many hours are in 1/4+3/5

I am Lyosha [343]

1/4 an hour is 60 divided by 4 times 1 which is 15 minutes.
3/5 an hour is 60 divided by 5 times 3 which is 36 minutes.
15 plus 36 equals 51 minutes which is less than 1 hour.

How To Multiply Decimals And Fractions

stich3 [128]

Answer:

$\large \boxed{\mathrm{view \ explanation}}$

Step-by-step explanation:

Convert the decimal into a fraction, then multiply both fractions.

For example:

0.5 × 1/4

0.5 is also 5/10 or 1/2.

1/2 × 1/4

Multiply both fractions.

(1 × 1)/(2 × 4)

= 1/8
