16 cups of water using 1/2 cup of measuring cup will fill a gallon of water.

To find the number of 1/2 cups that will fill a gallon, we simply need to know how many cups are in one gallon.

[tex]1cup = 0.0625 gallon[/tex]

This implies that

[tex]\frac{1}{2} cup = 0.03125 gallon[/tex]

Let's equate this and find how many cups are in one gallon.

[tex]\frac{1}{2} cup = 0.03125 gallon\\x cup = 1 gallon\\[/tex]

cross multiply both sides and make x the subject of formula

[tex]x = \frac{0.5}{0.03125}\\x = 16 cups[/tex]

The number of 1/2 cups that will fill 1 gallon will be 16 cups.

The measure of the angle y is 49 degrees if AB=AD and BC=DC; the answer is 49 degrees.

It is defined as a four-sided polygon in geometry having four edges and four corners. The kite is quadrilateral, having two pairs of congruent sides and it has one pair of opposite congruent angles.

The kite is given in the picture.

AB = AD

BC = DC

∠DBC + ∠CBD +  ∠C = 180  

From the property of kite: ∠DBC = ∠CBD

y + y + 82 = 180

y = 98/2

y = 49 degrees

Thus, the measure of the angle y is 49 degrees if AB=AD and BC=DC; the answer is 49 degrees.

The simplified value for 4 √84 x [tex]10^4[/tex] is 800 √21.

The exponent of a number shows how many times the number is multiplied by itself.

For example, 2×2×2×2 can be written as 24, as 2 is multiplied by itself 4 times. Here, 2 is called the "base" and 4 is called the "exponent" or "power." In general, xn means that x is multiplied by itself for n times.

Given:

4 √84 x [tex]10^4[/tex]

Now, first factorize 84 into prime factor

84 = 2 x 2 x 3 x 7

The, we can write it as

4 √84 x [tex]10^4[/tex]

=4 x √(2 x 2 x 3 x 7  x (10²)²)

There are 23 tickets which are purchased for children and 9 tickets are purchased for adults which cost total $148.

It is given in the question that 32 tickets are purchased by group which cost total $148.
Let the number of children of the group who are entering the zoo be x. Then the number of adults will be 32- x

Now cost of one ticket for adult = $7.50

Total amount spent on adult tickets = 7.50 × (32-x)

Similarly, cost of one ticket for child= $3.50

Total amount spent on children tickets = 3.50 × x =3.5x

Total amount spent by group on tickets =  $148
⇒ 7.5 × (32-x) + 3.5x = 148
⇒ 240 - 7.5x + 3.5x = 148
⇒ 7.5x - 3.5x = 240 - 148
⇒ 4x = 92
⇒ x = 23
Children = 23
Adults = 32-x = 32-23 = 9
Hence, 23 tickets are purchased for children and 9 tickets are purchased for adults.

The probability of a random sample of 80 households having a sample means a number of at least 2.55 televisions per household is 0.48173.

Given: Mean(μ) = 2.24, Standard deviation(σ) = 1.38, Sample size(n) = 1.28 and a random variable for X = 2.55

The formula to calculate the z-score from the mean. The standard deviation is:

z = (X - μ) / ( σ / √(n)) where,

z = z-score,

X = random variable,

μ = mean,

σ = standard deviation, and

n = sample size

Let's solve the given question:

We have,

Mean(μ) = 2.24,

Standard deviation(σ) = 1.38,

Sample size(n) = 80, and

a random variable for X = 2.55

As it is given sample means at least 2.55 so we have to find the Z(x ≥ 2.55).

Therefore, Z(x ≥ 2.55) = (2.55 - μ) / ( σ / √(n))

Substituting all values we get:

Z(x ≥ 2.55) = (2.55 - 2.24) / ( 1.38 / √(80))

Z(x ≥ 2.55) = 0.01 / 0.21819

Z(x ≥ 2.55) = 0.48173

Hence the probability of a random sample of 40 households having a sample means a number of at least 2.55 televisions per household is 0.48173.

The total amount due will be equal to $6.24.

This question can be solved by converting the situation into form of an equation. An equation may be defined as an expression which consists of numbers, variables related to each other by arithmetic expressions. The solution of equation often referred to as the variables for which the equation must be solved, are the values of the unknowable variables that satisfy the equality. The cost of video game is given as $12.98, and tax is equal to $0.78, and he paid an amount of $20. let the change left be x.

Total amount = cost of game + tax + change

$20 = $12.98 + $0.78 + x

$20 = $13.76 + x

=> x = $20 - $13.76

=> x = $6.24 which is the due amount.

Volume of a pyramid is calculated using the same basic formula as that of a cone: volume = (1/3) × base area × height, where height is the distance between the base and the apex. Then the height is 6 feet.

Using the equation volume = base area height / 3, one may calculate the volume of a regular square pyramid. Keep in mind that the base area is equal to the base edge length squared.

A polygonal base and an apex come together to form a polyhedron known as a pyramid. Volume of a pyramid is calculated using the same basic formula as that of a cone: volume = (1/3) × base area × height, where height is the distance between the base and the apex.

The volume of a square pyramid exists found by multiplying the area of the base by the height divided by 3.

32 = 4² × h/3

32 = 16 × h/3

Multiply both sides by 3

96 = 16 × h

Divide both sides by 16

H = 96/16

H = 6

Therefore, the height is 6 feet.

The covariance value between two variables says, days to 230 lbs and backfat thickness, is 0.48..

The covariance value between any two variables is used to determine whether the variables are changing in the same direction. It relates the two variables if they are from different data sets.

Let X and Y be two data sets with different values. Then the covariance between X and Y is given by

Cov ( X,Y) = ∑ ( X ᵢ– u) ( Yⱼ-v ) /n

Where are Xᵢ's elements in the X data set

Yⱼ→ elements of the Y set

μ → mean of X data set

ν→ mean of Y set

n→ total number of observations

As we have given two sets of data, let days to 230 lbs and backfat thickness be sets X and Y, respectively.

Now, we shall calculate the mean value for X and Y sets.

Mean of X set = (164+158+180 + +160+198+172+186+178+178+186)/10= 176

The mean of Y set =

 (1.0+ 1.1+ 1.2+ 1.4+1.2+1.3++1.1+1.3+1.4+1.0)/10 = 1.2

Xᵢ– μ - 12 -18 4 -16 22 -4 10 2 2 10

(Xᵢ - μ)(Yⱼ- ν) 2.4 1.8 0 - 3.2. 0 0.4 1 4.4 -2

∑ (Xᵢ - μ ) ( Yⱼ - ν) = 4.8

put all the values of variables in above formula we get,. Cov( X, Y) = 4.8 / 10 = 0.48 ..
