Solve the inequality

Hey there!

Question reads….

“Are the ratios 5:20 and 1:2 equivalent?”

Let’s find out if they are or not!

5:20

= 5 ÷ 5 : 20 ÷ 5

= 1 : 4

So, therefore, your answer is: NO because 5:20 = 1:4 NOT 1:2

Good luck on your assignment & enjoy your day!

Answer:

  450

Step-by-step explanation:

To evaluate the function for a particular value of the variable, put that value in place of the variable and do the arithmetic.

__

  y = 200×1.07^x   for x = 12

  y = 200×1.07^12 ≈ 200×2.252 ≈ 450

The deer population is about 450 after 12 years.

Answer:

[tex]5 meters^{2}[/tex] or 5m2

Step-by-step explanation:

1 meter^2 = 10000 cm

There for we could set up a ratio for this problem

[tex]\frac{x}{50000}: \frac{1}{10000}[/tex]

Using cross-multiplication we get:

[tex]10000x = 50000[/tex]

Divide 50,000 by 10000 we get:

[tex]5[/tex]

Therefore the answer is [tex]5 meters^{2}[/tex]

50 000 cm2 = 5 m2

Hope this helps! :)

Answer:

6/11

Step-by-step explanation:

5 of the counters are white that are taken out of the bag. That means if one more was taken out if the bag after that was the only white counter left then we can conclude that since there are 11 counters in the bag and 6 are white then, the probability of picking a white counter would be 6/11.

Have a great rest of your day

Answer:

P(of picking one of the white counters )= 8/11

Step-by-step explanation:

Firstly you need to identify the counters

White counters = 5

Unknown= 6

Total outcome = 11

Answer:

3^5 = 3 x 5 ( False )

6^3 = 216 ( True )

9^1 = 1^9 ( False )

Step-by-step explanation:

3^5

= 3 x 3 x 3 x 3 x 3

= 243

6^3

= 6 x 6 x 6

= 216

9^1 = 9

First question:  

    [tex]3^5=3*3*3*3*3[/tex] ≠ [tex]3*5[/tex]

    Answer: False

Second question:

   [tex]216 = 6 * 6 * 6 = 6^3[/tex]

    Answer: True

Third Question:

   [tex]9^1[/tex] ≠ [tex]1 * 1*1*1*1*1*1*1*1=1^9[/tex]

   Answer: False

Answer:

(a) The approximate distribution of the proportion pf of women who worked = 0.82, the standard distribution = 0.00738

The approximate distribution of the proportion pM of men who worked = 0.88, the standard distribution ≈ 0.01625

(b)  pM - pF =  0.06

While pF - pM = -0.06

The difference in the standard deviation ≈ 0.01025

(c) The probability that a higher proportion of women than men worked last year is 0

Step-by-step explanation:

(a) The given information are;

The percentage of college men that were employed last summer = 88%

The percentage of college women that were employed last summer = 82%

The number of college men interviewed in the survey = 400

The number of college women interviewed in the survey = 400

Therefore, given that the proportion of women that worked = 0.82, we have for the binomial distribution;

p = 0.82

q = 1 - 0.82 = 0.18

n = 400

Therefore;

p × n = 0.82 × 400 = 328 > 10

q × n = 0.18 × 400 = 72 > 10

Therefore, the binomial distribution is approximately normal

We have;

[tex]The \ mean = p = 0.82\\\\The \ standard \ deviation, \sigma = \sqrt{ \dfrac{p \times q}{{n} } }= \sqrt{ \dfrac{0.82 \times 0.18}{{400} }} \approx 0.01921\\[/tex]

Therefore, the approximate distribution of the proportion pf of women who worked = 0.82, the standard distribution ≈ 0.01921

Similarly, given that the proportion of male that worked = 0.88, we have for the binomial distribution;

p = 0.88

q = 1 - 0.88 = 0.12

n = 400

Therefore;

p × n = 0.88 × 400 = 352 > 10

q × n = 0.12 × 400 = 42 > 10

Therefore, the binomial distribution is approximately normal

We have;

[tex]The \ mean = p = 0.88\\\\The \ standard \ deviation, \sigma = \sqrt{ \dfrac{p \times q}{{n} } }= \sqrt{ \dfrac{0.88 \times 0.12}{{400} }} \approx 0.01625\\[/tex]

Therefore, the approximate distribution of the proportion pM of men who worked = 0.88, the standard distribution ≈ 0.01625

(b) Given two normal random variables, we have

The distribution of the difference the two normal random variable = A normal random variable

The mean of the difference = The difference of the two means = pM - pF = 0.88 - 0.82 = 0.06

While pF - pM = -0.06

The difference in the standard deviation, giving only the real values, is given as follows;

[tex]The \ difference \ in \ standard \ deviation = \sqrt{ \dfrac{p_1 \times q_1}{{n_1} } -\dfrac{p_2 \times q_2}{{n_2} } }\\\\= \sqrt{\dfrac{0.82 \times 0.18}{{400} }-\dfrac{0.88 \times 0.12}{{400} }} \approx 0.01025\\[/tex]

(c) When there is no difference between the the proportion of men and women that worked last summer, the probability that there is a difference = 0

Therefore, taking 0 as the standard score, we have;

[tex]z = \dfrac{0 - (-0.06)}{0.01025} \approx 5.86[/tex]

Given that the maximum values for a cumulative distribution table is approximately 4, we have that the probability that a higher proportion of women than men worked last year is 0.

Answer:

Let's find how many letters California has first, c-a-l-i-f-o-r-n-i-a has 10 letters.

Now let's find how many letter A's are in the word California, California has two a's in the word.

So there are 2 cards out of 10 that could possibly be selected as the letter A.

Your probability is:-

2/10 which simplifies to 1/5, if you wanted to make this a percentage as well;

1/5 * x/100

solve for x;

20%

The required probability of turning over an A is given as 20% or 0.2.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

Here,
California = C, a, l, i, f, o, r, n, i, a = 10 letters
So,
Number of card = 10

Now,
there are two a's in the card deck
So the probability of turning over an A,
= 2 / 10
= 0.2 or 20%

Thus, the required probability of turning over an A is given as 20% or 0.2.

Step-by-step explanation:

Hope this helps

Option B is the correct answer.

Given that, the amount of time it takes to give a dog a bath is most likely to be a function of the _____.

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.

The amount of time it takes to give a dog a bath is directly proportional to the size of the dog.

Therefore, option B is the correct answer.

Answer: 23.1

Step-by-step explanation:

By the inscribed angle theorem, we know the measure of arc DC is 120 degrees. So, we can set 120=7x-42.

162 = 7x

x = 162/7, which is about 23.1

Answer:

The number of lines for each angle tell you which angles are congruent.

The angle with one line in one triangle is the same as the angle with one line in the other triangle.

(a)

∠A ≅ ∠X

∠B ≅ ∠Z

∠C ≅ ∠Y

The dashes of the side lengths tell you which side lengths are congruent.

The line with one dash in one triangle is the same as the line with one dash in the other triangle.

(b)

AB ≅ XZ

AC ≅ XY

BC ≅ ZY

(c)

ΔBCA ≅ ΔZYX

Step-by-step explanation:

so, the function is

h(t) = -16t² + 30t + 6

we get the point of the extreme value(s) by finding the zero solution(s) of the first derivative of the function.

h'(t) = -32t + 30

finding the zero solution

-32t + 30 = 0

30 = 32t

t = 30/32 = 15/16 seconds

after 15/16 seconds (not even a full second) the ball reaches its maximum height.

the height at that maximum is then h(15/16) :

-16(15/16)² + 30×15/16 + 6 = - 15²/16 + 450/16 + 6 =

= -225/16 + 450/16 + 96/16 = 225/16 + 96/16 = 321/16 =

= 20.0625 ft

and so, the range (the interval or set of all valid functional values) is

0 <= h(t) <= 20.0625

as naturally, on a normal surface and environment, the height of the ball cannot go below 0 (when it hits the ground, it's over).
