x - 2y = 0
2x + y = 5

Answers

Answer 1
x - 2y = 0
x = 2y

2x+ y = 5
Replace x
2(2y) + y = 5
4y + y = 5
5 y = 5
y = 5/5 = 1

x - 2y = 0
x - 2(1) = 0
x - 2 = 0
x = 2

x=2 and y=1

Write the equation of a circle that has a center of (-8, 0)
and a diameter of 8.

Answers

Answer:

(x+8)^2+y^2=16

Step-by-step explanation:

The equation for a circle in center-radius form is

(x-h)^2+(y-k)^2=r^2

where (h,k) is the center and r is the radius.

We are given the diameter is 8 so the radius is 8/2=4.

We are also given (h,k) is (-8,0).

The equation for the circle is

(x--8)^2+(y-0)^2=4^2

(x+8)^2+y^2=16

Raul tossed a coin and spin a spinner with three equal sections. Based upon the results, what is the probability of tossing a tail and spinning a 2?
F. 1/10
G. 1/9
H. 1/8
J. 3/20

Answers

H is the answer for the question

The experimental probability of tossing a tail and spinning a 2 is given by: Option H: 1/8

What is experimental probability?

Experimental probability calculates the probability of some event from the results of experiments.

For an event E, we get the experimental probability of that event

[tex]P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}}[/tex]

where, [tex]P_e(E)[/tex] is denoting experimental probability of occurrence of E.

For this case, the table is missing, the results recorded were:

Toss         Spin        Frequency

Head          1                 2

Head          2                6

Head          3                7

Tail             1                 7

Tail             2                5

Tail             3                13

That means total number of times experiment was done was: 2+6+7+7+5+13=40

Let we take E = event of  tossing a tail and spinning a 2

Thus, from the table, we see that E occurred 5 times.

Thus, based on this, the experimental probability of occurrence of E is:

[tex]P_e(E) = \dfrac{5}{40} = \dfrac{1}{8}[/tex] (option H)

Two women share 60 eggs
it the ratio 1 to 2. How many eggs does each recieves?

Answers

Answer:

One woman receive 20 eggs

And the other receive 40 Egss

Explanation:

So the ratio is 1:2 so we gonna add them to get the total so 1+2=3

To find each amount divide each by the total so 1/3 and 2/3

To find the first amount

1/3×60=20

To find the other amount you can either subtract

60-20=40

or

2/3×60=40

One woman receive 20 eggs and the other receive 40 eggs.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

So the ratio is 1:2 so we have to add them to get the total.

So 1+2=3

In order to find each amount divide each by the total.

So 1/3 and 2/3

The first amount,

1/3 × 60 = 20

The other amount,

60-20=40

or

2/3 × 60 = 40

Thus, One woman receive 20 eggs and the other receive 40 eggs.

  D  9/DF = 18/16

Step-by-step explanation:

Corresponding sides are proportional. The proportions based on a given similarity statement can be written 4 ways.

For these isosceles triangles, the similarity statement could be written either of two ways:

  ΔDEF ~ ΔABC  or  ΔDEF ~ ΔCBA

Corresponding sides will depend on the similarity statement you use. Using the first one, they are ...

  DF and AC (short sides)

  DE and AB (long sides)

  EF and BC (long sides)

For each (short side, long side) pair, we can write the proportion 4 ways:

DF/DE = AC/AB  ⇒  DF/9 = 16/18DF/AC = DE/AB  ⇒  DF/16 = 9/18DE/DF = AB/AC  ⇒  9/DF = 18/16 . . . . . matches choice DAC/DF = AB/DE  ⇒  16/DF = 18/9

Using the other pair of long sides, or using the other similarity statement, the numerical proportions are the same as the ones listed above.

Answers

Answer:

Step-by-step explanation:

there is a 4 to 7 ratio in the first situation.

so if there is (4*3) the it would be (7*3) so it would be 21 carnations

this gives 12+21 for a total of 33 flowers.

the ratio is 4/7 so you could also go (4/7)(12) and then add that to the original 12 in the boqouet in order to get the same answer. Hope this helps!

Given P(A) = 0.74, P(B) = 0.6 and P(ANB) = 0.494, find the value of
P(AB), rounding to the nearest thousandth, if necessary.

Answers

Step-by-step explanation: Since we have given, P(A) = 0.75 and P(A|B) =0.8 .

So, P(A∩B) = P(B|A)× P(A) = 0.8×0.75 =0.6 .

We have given P(B|A') = 0.6

P(A’∩B) = P(B|A')×P(A') = 0.6 × 0.25 = 0.15.

P(B) = P(A∩B) + P(A'∩B) = 0.6 + 0.15 = 0.75.

=> P(A|B) = (∩)()=0.60.75

Answer:

B. 44°

Step-by-step explanation:

That's it.

90° + 46° + 44° = 180°

Answer:

m2 = 44°.

Step-by-step explanation:

The sum of the measures of the angles of a triangle always equals 180°.

One of the angles is a right angle, so its measure is 90°.

Let n equal m2.

90+46+n=180

n=44

Therefore, m2 = 44°.
