Answer:

$\boxed{\sf \ \ \ answer \ b. \ \ +5 \ \ \ }$

Step-by-step explanation:

Hello

let's assume that we are looking for x >=0

$4x^2=100 \dfrac{4x^2}{4}=x^2=\dfrac{100}{4}=25\\\sqrt{x^2}=25\\ |x| = 5 x = 5 \ or \ x=-5$

Let's assume that we are looking for x>=0

so the correct answer is 5

If two dice are thrown whats si the probability that they will add to 9?A2/36B3/36C3/36D4/36

GuDViN [60]

Answer:

D. $\frac{4}{36}$

Step-by-step explanation:

Solution,

Two dice are thrown.

So we have to find out the total number of outcomes.

$(1,1),\ (1,2),\ (1,3),\ (1,4),\ (1,5),\ (1,6)$

$(2,1),\ (2,2),\ (2,3),\ (2,4),\ (2,5),\ (2,6)$

$(3,1),\ (3,2),\ (3,3),\ (3,4),\ (3,5),\ (3,6)$

$(4,1),\ (4,2),\ (4,3),\ (4,4),\ (4,5),\ (4,6)$

$(5,1),\ (5,2),\ (5,3),\ (5,4),\ (5,5),\ (5,6)$

$(6,1),\ (6,2),\ (6,3),\ (6,4),\ (6,5),\ (6,6)$

The total number of outcomes = $36$

We have to find out the probability of outcomes that add up to 9.

So, Possible outcomes are;

The total number of possible outcomes = $4$

Now, according to the formula of probability,

$P(E)=\frac{Total\ number\ of\ Possible\ outcomes}{Total\ Number\ of\ outcomes}$

$P(of\ add\ up\ to\ 9)=\frac{4}{36}$

Hence the correct option is D)4/36.

Four points are drawn on the coordinate plane and connected with straight lines to form a rectangle. Three of the vertices of th

pantera1 [17]

You have 2 points with the same x value of 2 and 2 points with the same y value of 4.

You now need 2 points with the same x value of 4 ( you are given 1) and 2 y values of 1 ( you are given 1.

The missing point would need to be (4,1)

The width would be x2-x1 = 4-2 = 2 units

The length would be y2-y1 = 4-1 = 3 units

Area = 3x 2 = 6 square units
