Answer:

$1.17

Step-by-step explanation:

change = 20 - (3.99(3) + 2.99(1) + 3.09(1) + 0.78)

            = 20 - (11.97 + 2.99 + 3.09 + 0.78)

            = 20 - 18.83

            = 1.17

Answer: 90km/hour

Step-by-step explanation:

The formula for speed is given as:

= Distance / Time

where,

Distance = 120km

Time = 80 minutes = 80/60 = 1 1/3 hours

Speed = Distance / Time

= 120 / 1 1/3

= 120 / 4/3

= 120 × 3/4

= 90km/hour

The speed is 90km/hour.

To find the vector x such that T(x) = (3, 8), we need to solve the system of equations:

x₁ + x₂ = 3

4x₁ + 5x₂ = 8

We can rewrite this system in matrix form as Ax = b, where A is the coefficient matrix, x is the vector of variables, and b is the vector on the right-hand side:

[1 1] [x₁] [3]

[4 5] [x₂] = [8]

To solve this system, we can invert the coefficient matrix A and multiply it by the vector b:

x = A⁻¹ * b

To find A⁻¹, we calculate the inverse of the coefficient matrix A:

A⁻¹ = 1 / (1 * 5 - 4 * 1) * [5 -1]

[-4 1]

Multiplying A⁻¹ by b gives us the solution vector x:

x = [5 -1] * [3]

[8]

= [5 * 3 + (-1) * 8]

[-4 * 3 + 1 * 8]

= [7]

[20]

Therefore, the vector x that satisfies T(x) = (3, 8) is x = (7, 20).

The perimeter of the fence that José will place around his house will be 24.50 meters.

To find the perimeter of the fence that José will place around his house, we need to determine the length of all four sides of the fence.
Given that the shorter side of the fence is one-fourth (1/4) of the length of the longest side, which is 9.80m, we can calculate the length of the shorter side as follows:

Length of shorter side = (1/4) * 9.80m = 2.45m

Since the fence will form a rectangle around José's house, opposite sides will have the same length. Therefore, the length of the other shorter side will also be 2.45m.

To find the perimeter, we need to add up the lengths of all four sides of the fence:
Perimeter = Length of longer side + Length of shorter side + Length of longer side + Length of shorter side
        = 9.80m + 2.45m + 9.80m + 2.45m
        = 24.50m
So, the perimeter of the fence that José will place around his house will be 24.50 meters.
In conclusion, the perimeter of the fence that will be placed around Raúl's house is 24.50 meters.

The sequence is defined by adding 2 to the previous term. We can find the first six partial sums by adding the terms of the sequence together up to a certain point.

Given that the first term is 4, we can start calculating the partial sums:

S1 = 4

S2 = 4 + 6 = 10

S3 = 4 + 6 + 8 = 18

S4 = 4 + 6 + 8 + 10 = 28

S5 = 4 + 6 + 8 + 10 + 12 = 40

S6 = 4 + 6 + 8 + 10 + 12 + 14 = 54

So the first six partial sums are:

S1 = 4

S2 = 10

S3 = 18

S4 = 28

S5 = 40

S6 = 54

The 31st term of the given sequence will be 129.

An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.

\(T_n = a + (n-1)d\)

Given sequence;

309, 303, 297,...

The first term, a1 = 309

The common difference, d = 303 - 309 = -6

The 31st term will be

n = 31

\(T_n = a + (n-1)d\)

\(T_{31} = 309 + (31-1)(-6)\\\\T_{31} = 309 + (30)(-6)\\\\T_{31} = 309 + (-180)\\\\T_{31} = 129\)

Hence, The 31st term of the given sequence will be 129.

Answer:   20 ounces box of cheerios is cheaper.

Step-by-step explanation:

If 10 ounce box of cheerios cost $2.80  and 20 ounce cost $5.20  then to find which is cheaper, you need to find the unit price which is the cost of an ounce.

Divide the money by the amount of ounces.

2.80 / 10 =   0.28   which is 28 cents per ounce.

5.20/20 =  0.26  which is 26 cents per ounce.

So the 20 box of cheerios is cheaper because it is 2 cents less.

EF as a decimal rounded to the nearest tenth is 60.9.

A, I looked online and came across this statistic.

OM is probably perpendicular to CD and EF is perpendicular to ON, and I'm assuming there's more information there.

The chords are similarly split in half by the diameters that intersect them at right angles, so CM = (1/2) CD = 28.

r2 = OM2 + CM2 = 202 + 282 = 1184 r = 474 b; FN is the leg of a right triangle with other leg ON=16 and hypotenuse OF=r because it is a radius; r2 = OM2 + CM2 = 202 + 282 = r = 474 b.

r2 - ON2 = 1184 - 162 = 1184 - 256 = 928 = FN2 = 928

C, By the perpendicular diameter bisecting a chord theorem, EF is twice as large as FN.

EF = 2√928

The probability that a randomly selected person is infected with disease D is 11%. This is calculated based on the given information regarding the occurrence of minor cold-like symptoms and the associated probabilities of being infected with D.

Let's denote the event of experiencing minor cold-like symptoms as S, and the event of being infected with disease D as D. We are given that P(S) = 0.2 (20% of people experience these symptoms).

We also know that within the group of people experiencing symptoms (S), P(D|S) = 0.35 (35% chance they are infected with D), and within the group of people not experiencing symptoms (~S), P(D|~S) = 0.05 (5% chance they are infected with D).

To find the probability of being infected with D, we can use Bayes' theorem:

P(D) = P(D|S) * P(S) + P(D|~S) * P(~S)

Substituting the given values:

P(D) = 0.35 * 0.2 + 0.05 * (1 - 0.2)

Simplifying:

P(D) = 0.07 + 0.05 * 0.8
P(D) = 0.07 + 0.04
P(D) = 0.11

Therefore, the probability that a randomly selected person is infected with disease D is 0.11, or 11%.

The mean and variance of the number x of unusable fasteners in a randomly selected box are about 150 and 150 respectively.

Poisson distribution is a distribution function useful for characterizing events with very low probabilities of occurrence within some definite time or space. It is used when the number of trials is very large and the probability of success is comparatively small.

In Poisson distribution, the mean is defined as:

λ = np

where n = number of items and p = probability of success

Given: n = 5000 and p = 3/100 = 0.03

Thus,  λ = np = 5000 * 0.03 = 150

Since the mean and variance are equal in Poisson distribution. Thus, the variance (σ²) =  150
