The stock market dropped 220 points on Monday. It lost another 48 points on Tuesday, and on Wednesday, it gained 96 points. What
Leona [35]

Answer: 48 points gained in those 3 days.

Subtract 220 with 48, then add 96. Last step would be subtracting 220 with the amount they have now in those 3 days to find how much points the stock market gained in those 3 days.

Subtract 220-48.It‘ll be 172.

Add 172 with 96. 172+96=268.

Subtract 268 with how much points the stock market had 3 days ago. 268-220. So it would be about 48 points gained.

Number 10Please just show the math and not the sentence explanations, I just want to use this problem as an example :)
Morgarella [4.7K]

Explanation

We are given the following right-angled triangle:

We are required to determine the indicated angle in the given figure.

This is achieved thus:

According to the image, we have:

\begin{gathered} Opposite=9 \\ Adjacent=21 \end{gathered}

Therefore, we have:

\begin{gathered} \tan\theta=\frac{opposite}{adjacent} \\ \tan\theta=\frac{9}{21} \\ \theta=\tan^{-1}(\frac{9}{21}) \\ \theta\approx23\degree \end{gathered}

Hence, the answer is:

23\degree

Sketch the areas under the standard normal curve over
SOVA2 [1]

Answer:

a) P(Z

b) P(Z>0.15)=1-0.560=0.440

c) P(-1.40

Step-by-step explanation:

a)To the left of z = 0.72.

For this case the shaded area is on the figure 1 attached.

And we can find the area with the normal standard table of with the following excel code:

=NORM.DIST(0.72,0,1,TRUE)

P(Z

b)To the right of z = 0.15.

For this case the shaded area is on the figure 2 attached.

And we can find the area with the normal standard table of with the following excel code:

=1-NORM.DIST(0.15,0,1,TRUE)

P(Z>0.15)=1-0.560=0.440

c)Between z = -1.40 and z = 2.03.

For this case the shaded area is on the figure 3 attached.

And we can find the area with the normal standard table of with the following excel code:

=NORM.DIST(2.03,0,1,TRUE)-NORM.DIST(-1.40,0,1,TRUE)

P(-1.40
