What are proportions?

Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

Let the number of baskets she be x.

Now, 6:10 :: x:25

⇒ 6/10 = x/25

⇒ 10x =150

⇒ x=15

Therefore, number of baskets Lillianne made out of 25 attempted is 15.

Fawns Fawns between 1 and 5 months old in Mesa Verde National Park have a body weight that is approximately normally distributed with mean m 5 27.2 kilograms and standard deviation s 5 4.3 kilograms (based on information from The Mule Deer of Mesa Verde National Park, by G. W. Mierau and J. L. Schmidt, Mesa Verde Museum Association). Let x be the weight of a fawn in kilograms. Convert each of the following x intervals to z intervals.

The conversion of the respective x-intervals to z-intervals are;  z < 0.65; z > -1.91; 1.12 < z < 1.81

What is the z-interval?

The formula for z-score is;

z = (x - x')/σ

where;

x = the value that is converted to z-score

x' is the mean = 27.2 kg

σ is standard deviation = 4.3 kg

a) We want to convert x < 30 to z-interval;

Z-score is;

z = (30 - 27.2)/4.3

z = 0.65

Thus, the z-interval of x < 30 is; z < 0.65

b) We want to convert x > 19 to z-interval;

Z-score is;

z = (19 - 27.2)/4.3

z = - 1.91

Thus, the z-interval of x > 19 is  z > -1.91

c) We want to convert 32 < x < 35 to z-interval;

z-score for x = 32 is;

z₁ = (32 - 27.2)/4.3

z₁ = 1.12

z-score for x = 35

z₂ = (35 - 27.2)/4.3

z₂ = 1.81

Thus, the z - interval for 32 < x < 35 is 1.12 < z < 1.81

Answer:

a) x < 30 = z < 0.65

b) 19 < x = -1.91 < z

Or x > 19 = z > -1.91

c) 32 < x < 35 = 1.12 < z < 1.81

Step-by-step explanation:

The standardized score for any value is the value minus the mean then divided by the standard deviation.

z = (x - xbar)/σ

x = the value to be standardized, that is, converted to z-score

xbar = mean = 27.2 kg

σ = standard deviation = 4.3 kg

a) For x < 30

We standardize the 30 kg weight first

z = (x - xbar)/σ = (30 - 27.2)/4.3 = 0.65

x < 30 = z < 0.65

b) For 19 < x

We standardize the 19 kg weight first

z = (x - xbar)/σ = (19 - 27.2)/4.3 = - 1.91

19 < x = - 1.91 < z

Or x > 19 = z > - 1.91

c) For 32 < x < 35

We standardize the 32 kg and 35 kg weights first

z = (x - xbar)/σ

z₁ = (32 - 27.2)/4.3 = 1.12

z₂ = (35 - 27.2)/4.3 = 1.81

32 < x < 35 = 1.12 < z < 1.81

Change 12.39% to decimal

Answers

.1239
A decimal represents a value out of a whole, the "." representing everything under the amount of a whole (1). A percentage is essentially the same thing, except the "%" sign basically replaces the decimal. To convert a percentage to a decimal, move the decimal (and if there isn't one, add one to the right of the last number). Then, move that decimal two places to the right. For every empty space you move, add a zero there.

What is the volume of a room 84 feet long, 48 feet wide and 28 ft high​

Answers

Answer:

112,896 ft. cubed

Step-by-step explanation:

Volume is length times width times height. We have all three measures. 84*48*28 equals 112,896. Becuase we are solving for volume, the unit of measure has to be cubed (to the square root of 3). Therefore, the volume of the room is 112,896 ft. cubed.

A store is selling two mixtures of nuts in 20-ounce bags. The first mixture has 15 ounces of peanuts combined with five ounces of cashews, and costs $4.25. The second mixture has five ounces of peanuts and 15 ounces of cashews, and costs $6.75. How much does one ounce of peanuts and one ounce of cashews cost?

Answers

Given that a store is selling two mixtures of nuts in 20-ounce bags: peanuts and cashews.

Let the cost of one ounce of peanut be x and the cost of one ounce of cashew be y, then

Given that the first mixture has 15 ounces of peanuts combined with five ounces of cashews, and costs $4.25 implies that 15x + 5y = 4.25

Also, given that the second mixture has five ounces of peanuts and 15 ounces of cashews, and costs $6.75 mplies that 5x + 15y = 6.75

To obtain the cost of one ounce of peanuts and one ounce of cashews, we solve the two equations above, simultaneously:


Therefore, one ounce of peanuts and one ounce of cashews cost $0.15 and $0.40 respectively.

Answer: peanuts $0.15 and $0.40 cashews
