From the diagram, we are given that triangle ABC and triangle ADC shares the same side AC, so it means both triangles have one congruent side.

We are also given that angle BAC and angle DAC are equal.

If we want to prove the triangles congruent using Angle-Angle-Side congruent postulate, we need to see one angle in each triangle that is congruent. We will need the information either: ACB = ACD or ABC = ADC

Correct answer: fourth option

The standard deviation is 4 games

A standard deviation (or σ) is a measure of how dispersed the facts are in relation to the mean. Low general deviation method statistics are clustered around the imply, and excessive trendy deviation indicates facts are more unfold.

Don't forget the statistics set: 2, 1, 3, 2, four. The mean and the sum of squares of deviations of the observations from the mean will be 2. 4 and 5.2, respectively. as a consequence, the same standard deviation could be √(5.2/5) = 1.01.

In data, the same old deviation is a degree of the quantity of variant or dispersion of a set of values. A low preferred deviation indicates that the values tend to be close to the mean of the set, while a high general deviation shows that the values unfold out over a much broader variety.

Given that,

mean = μ = 18

standard deviation = Σ = 6

n = 2

μ x = μ = 18 games

√ x = Σ / √ = 6

√2 = 4 games

In 2012, the population of New Zealand was approximately 4.43

mrs_skeptik [129]

Answer: 6.71 × 10^6 people

Step-by-step explanation:

Given that the population of New Zealand was approximately 4.43million people. In the same year, the population of Belgium was approximately 11.14 million people.

The difference in number of population will be

(11.14 - 4.43) millions

= 6.71 millions people

Expressing the answer by using scientific notation will be

6.71 × 10^6 people.

Therefore, 6.71 × 10^6 people live in Belgium than in New Zealand

Gnom [1K]

Answer:

7/10

Step-by-step explanation:

If you have 10 sweets

Your brother eats 3

You eat 4

3 + 4 = 7

7 out of ten = 7/10

So therefore the answer is 7/10

Find the vertex, focus, directrix, and focal width of the parabola: -1/40x^2=y

dimulka [17.4K]

For
(x-h)^2=4p(y-k)
vertex is (h,k)
distance from vertex to directix=p=distance from vertex to focus
|4p|=focal width

remember, focus is on the side of the parabola where it opens and directix is at the back
when p is negative, it opens down
when p is positive, it opens up

look at equation
-1/40(x-0)^2=(y-0)
times -40 to both sides
(x-0)^2=-40(y-0)
(x-0)^2=4(-10)(y-0)
vertex=(0,0)
p=-10,it's negative so it opens down

focus is 10 units below vertex (y direction)
focus=(0,-10)

diretix is 10 above
directix is y=10

focal width=|4p|=|4(-10)|=|-40|=40

vertex=(0,0)
focus=(0,-10)
directix is y=10
focal width=40 units
