Answer:

-9.32*10^- is -9.32*10^-5

Answer:

d=√((x_2-x_1)²+(y_2-y_1)²)

d=√((2-(-4))²+(1-(-3))²)

d=√(6²+4²)

d=√36+16

d=√52

d=7.21110255...

d=7.2

Step-by-step explanation:

d=7.2

The distance between the points on the coordinate plane is 7.2 units.

Coordinate geometry is the study of geometry using the coordinate points.  It provides a link between geometry and algebra through line graphs and curves.

For the given situation,

The points are (x1, y1) be (–4, –3) and (x2, y2) be (2, 1)

The formula for the distance between points,

[tex]d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }[/tex]

On substituting the above points,

⇒ [tex]d=\sqrt{(2-(-4))^{2}+(1-(-3))^{2} }[/tex]

⇒ [tex]d=\sqrt{6^{2}+4^{2} }[/tex]

⇒ [tex]d=\sqrt{52}[/tex]

⇒ [tex]d=7.211[/tex] ≈ [tex]7.2[/tex]

Hence we can conclude that the distance between the points on the coordinate plane is 7.2 units.

Answer:

a) "impossible event"

b) "certain event"

c) Letter A.

Step-by-step explanation:

a) An event with probability 0 is said to be:

These events are called "impossible events" (but there are more complex cases where we can have probabilities 0, and the events are not necessarily impossible events)

b) An event with probability 1 is said to be

An event with a probability of 1 is an event that will happen, these events are called "certain event"

c) The probability for each outcome of an unbiased experiment of N different outcomes will be 1/N

for example, for a 6-side dice we have 6 outcomes, then the probability of each outcome is 1/6.

For the coin, we have 2 outcomes, then the probability of each outcome is 1/2

Probability of getting a head = 1/2 = 0.5

In the image, we can see that letter A is on the 0.5 value, then the correct answer here is A.

Answer:

Answer:

144

Step-by-step explanation:

to find the missing angle in side of the triangle we subtract 111 and 33 from 180

180-111-33=36

so the angle inside of the triangle equals 36 to find the one on the outside of the triangle we subtract 36 from 180

180-36 which equals 144 so 1=144

Answer:

2x-60=180

Step-by-step explanation:

RQS = x-6

the two angles add to make 180 because they are on a straight line

so x + x-6 = 180

therfore, 2x+6 = 180

Answer:

5 units

Step-by-step explanation:

Answer:

ab = 24

so ac is half, so

ac = 12

and the radius is 13,

draw a line from a to o

and its tall will be 13 because it is the radius and o is the center

now use Pythagoras rule

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

put numbers

[tex] {12}^{2} + {b}^{2} = {13}^{2} [/tex]

and solve for b

b = 5

and that is the side we want

Answer:

a. 1

b. any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1

Step-by-step explanation:

Answer and explanation:

a) This value is equal to one because it is just the number divided by itself.

b) Since any number divided by itself is equal to 1, 6^3/6^3 also has to equal to one. This also means that when we bring the 6^3 up to the numerator, the equation 6^3-3, which simplifies into 6^0 also has to equal 1, because it is equivalent to being divided by itself.

The standard deviation is 2.08.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

We have the data,

X     :   0     1     2     5     10

P(X) :  0.4  0.2  0.2  0.1  0.1

CF   : 0.4   0.6  0.8  0.9  1

Sum of fx = 2.5

Mean = 2.5

Deviation X = -2.1 -2.3 -2.1 -2 -1.5

X² = 4.41 5.29 4.41 4 2.25

fX² = 1.764 1.058 0.882 0.4 2.225

Now, standard deviation

= √4.329/1

= 2.08

Answer:

[tex]a=4\ m/s^2[/tex]

Step-by-step explanation:

Given that,

The velocity of a car increases from 4 m/s at 2 sec to 32 m/s at 9 sec.

We need to find the car's average acceleration. It can be given by the change in velocity divided by the change in time. So,

[tex]a=\dfrac{v-u}{t_2-t_1}\\\\a=\dfrac{32-4}{9-2}\\\\a=4\ m/s^2[/tex]

So, the car's average acceleration is equal to [tex]4\ m/s^2[/tex].

Answer:

90, 70, 20

Step-by-step explanation:

The measure of an angle is 180 so if you add up 90,70,and 20 you get a total of 180

Answer:

70, 20, 90

Step-by-step explanation:

For all triangles, the sum of the angles is 180.

I got these three angles 70, 20, 90.

To double check you can add all the angles together.

70 + 20 = 90, 90 + 90 = 180
