Answer:

For the first one, divide the price by the number of pounds to get price per pound.

$8.75/2.5 lbs = $3.5/lb

$9.75/3 lbs = $3.25/lb

Then take the difference $3.5 - $3.25 = $0.25 Same thing for the 2nd one. Divide $12.35/11

If you had 10 lbs, at $1.54 per pound..........

Would be over $15, so 11 pounds would be even more. The other prices would cost even

Soooooooo...... answer is $1.12

Step-by-step explanation:

Erm...the explanation is sorta in the answer E...


Hope this helps!!!

In the last chapter, we looked at three outliers arising from a plot of Average Wind Speed by Month in the Hopkins Forest. Each
Aloiza [94]

Answer:

Step-by-step explanation:

Hello!

We have the information of the average wind speed for three months:

February:

Mean: 2.324

SD: 1.577

Otlier: 6.73 mph

June:

Mean: 0.857

SD: 0.795

Otlier: 3.93 mph

August

Mean: 0.63

SD: 0.597

Outlier: 2.53mph

a)

Z=  X - μ ~N(0;1)

δ

Z_{February}= \frac{6.73 - 2.324}{1.577}

Z_{Februar}= 2.793 ≅2.79

Z_{June}= \frac{3.93 - 0.857 }{0.795}

Z_{June}= 3.87

Z_{August}= \frac{2.53 - 0.63}{0.597}

Z_{Augus}= 3.182 ≅ 3.18

b)

Comparing the three Z-scores you can say that the strongest wind event was in June. The number obtained means that is the furthest one in relation to the mean.

Answer:

when two inscribed angles in one circle both equal 75°, the two angles must intercept the same arc that measures 75°.

Step-by-step Explanation:

The relationship between an intercepted arc and an inscribed angle is given as:

the measure of the intercepted arc = twice the inscribed angle that intercepts it.

Also, by virtue of this, when two inscribed angles intercepts the same arc, both inscribed angles are said to be congruent. And the measure of both angles equal the measure of the arc they both intercept.

Therefore, if the measure of an arc, that is intercepted by 2 inscribed angles, is given as 75°, both inscribed angles equal 75° as well. Thus, each of the inscribed angles is half the measure of the intercepted arc.

Therefore, the statement that is true about inscribed angles is: "when two inscribed angles in one circle both equal 75°, the two angles must intercept the same arc that measures 75°."

For the equations given below, which statement is true?
seraphim [82]

Answer:

D. The equations do not have the same solution because the second eqlition can never be obtained when multiplying the first

equation by any value

Step-by-step explanation:

-21=14 Equ(1)

6.1=-42 Equ(2)

Multiplying the first equation by -3 will give

-63= -42

Which is not equivalent to the second equation

Multiplying the first equation by 3, we have

-63=42

Not equivalent to the second equation

Multiplying both sides of the first equation by -4, we have

84=56

Not equivalent to the second equation

D. The equations do not have the same solution because the second eqlition can never be obtained when multiplying the first

equation by any value

Please help!! I don't understand this!
e-lub [12.9K]

Answer: The first one is "translated 4 units down". The second one is "vertically stretched by a factor of 4".

Recall that y = f(x). When we say f(x)-4, we really mean y-4 so that means each y coordinate of all the points on the graph have been reduced by 4. Visually this shifts the graph down 4 units. A translation in geometry is the technical term for shifting.

When we say 4*f(x), we are multiplying each y coordinate by 4. A point like (1,2) turns into (1,8) for instance. If you apply this to every point on the graph, then the curve is stretched vertically to be 4 times taller than it usually is; which is an informal way of saying "vertically stretched by a factor of 4"
