choose the best selection for the quadrilateral with vertices at the following points: (-3,0), (3-, -3), (0, -3), (0,0)

Answer:

A = $5,984.74

A = P + I where

P (principal) = $5,000.00

I (interest) = $984.74

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 3/100

r = 0.03 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 5,000.00(1 + 0.03/12)(12)(6)

A = 5,000.00(1 + 0.0025)(72)

A = $5,984.74

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $5,000.00 at a rate of 3% per year compounded 12 times per year over 6 years is $5,984.74.

Answer:

There is no significant evidence to support the claim that an association between seed density and lawn quality exists.

Step-by-step explanation:

Given the data :

Seed Density Lawn Quality

1 30

1 40

2 40

3 40

3 50

3 65

4 50

5 50

Using technology to obtain the correlation Coefficient between seed density and lawn quality, the Coefficient, R = 0.6

H0 : ρ = 0

H1 : ρ ≠ 0

We can then calculate the test statistic :

Test statistic = r / √(1 - r²) / (n - 2)

Test statistic = 0.6 / √(1 - 0.6²) / (8 - 2)

Test statistic = 0.6 / 0.3265986

Test statistic = 1.837

Pvalue from test statistic : = 0.11583

α = 0.01

Pvalue > α ;

We fail to reject the null

Answer:

I’m pretty sure it’d be 17 because 15 is the lower extreme.

Step-by-step explanation:

I just learned this. 17 would be the Q1, 20 would be Q2, and 23 would be Q3. I hope this helped you out :)

Answer:

length = 12

width = 15

Step-by-step explanation:

if you foil (x+7)(x+10) you get:

x²+17x-110 = 0

the factors are:

(x+22)(x-5) = 0

x = -22 and 5

we can dismiss the negative as irrelevant for a measure; therefore, x = 5

length = 5+7, or 12

width = 5+10, or 15

Answer:

Incomplete question, but the binomial distribution with [tex]p = 0.9[/tex] and [tex]n = 4[/tex] is used to solve the questions.

Step-by-step explanation:

For each disk, there are only two possible outcomes. Either it passes the first test, or it does not. The probability of a disk passing the first test is independent of any other disk. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Suppose that past data indicate that the probability that a compact-disk player passes the first test is 0.9.

This means that [tex]p = 0.9[/tex]

4 compact-disk players are randomly selected

This means that [tex]n = 4[/tex]

Answer:

It must be a rectangle with dimension of either 1 by 8  or 2 by 4

Step-by-step explanation:

V = l*w*h

32 = l*w*4

32/4 = l*w*4/4

8 = l*w

We could have 1*8

We could have 2*4

It must be a rectangle

It must be a rectangle with dimension of either 1 by 8  or 2 by 4

Answer:

I believe it is 761 is the cost the roofer will charge.

Step-by-step explanation:

First: Multiply 32 with 19.25 (standing for h), which equals to 616.

Second: Add 616 with 145, which adds up to 761.

Answer:

a)  0.2347, 0.0007

b) 1.30

c) 0.63

Step-by-step explanation:

Given –  

Mean = 73.4

Sigma = 4.7

Probability that the speed is greater than 70 is  

P (X>70) = P (z> (70-73.4)/4.7) = P (z>-0.72) = 0.7653

a) The probability that a car is not speeding = 1 - 0.7653 = 0.2347

The probability that all 5 cars are not speeding = (0.2347)5 = 0.0007

b) E (X) = 1/p = 1/0.7653 = 1.30  

c) Standard deviation = Sqrt (1-p/p) = (1-0.7653)/0.7653 = 0.63

Answer:

Area=120 cm

Step-by-step explanation:

I think for each separate figure you find the area and then add them up to find the total area. The formula to find the area here is length times width or base times height.

First figure: 12 times 5= 60 cm

Second figure=8 times 5=40cm

Together we have 100cm as our area, that might be wrong, look in the comments, thanks for correcting me :)

Answer:

4

Step-by-step explanation:

BCD is a right triangle. The Pythagorean Theorem applies; a^2 + b^2 = c^2, with c being the hypotenuse. a^2 + 9 = 25, so a^2 = 16, so a = 4

Answer:

The answer is (h).

Step-by-step explanation:

When y = 2^x is shifted 4 units left, the x shifts 4 units to the left and x becomes (x+4). When the graph is shifted to units down, y has to be subtracted by 2.

The function becomes

y = 2^(x+4) -2.

Finally, you shift -2 to the same side as y.

This becomes

y+2 = 2^(x+4) which is (h)

Answer:

Jose's father weighs 70 kilograms.

Step-by-step explanation:

Given that Jose weighs 25 kg, while his father is 5 kg less than 3 times Jose's weight, to determine what is the weight of Jose father the following calculation must be performed:

Jose = 25

Father = 3J - 5

3 x 25 - 5 = Father

75 - 5 = X

70 = X

Therefore, Jose's father weighs 70 kilograms.

Answer:

  38.63 m

Step-by-step explanation:

The definition of the perimeter tells you that you need to find the lengths of each of the edges of the figure.

The diagonal edge at left is the hypotenuse of a right triangle with legs 4 and 6. They Pythagorean theorem tells you that length is ...

  d = √(4² +6²) = √52 ≈ 7.21 . . . meters

The straight line across the top is marked 9 meters.

The semicircle length is half the circumference of a circle with diameter 6 m. That semicircle length is ...

  semicircle length = (1/2)πd = (1/2)(3.14)(6 m) = 9.42 m

The straight bottom edge of the figure is 4+9 = 13 m.

Then the sum of lengths around the figure is ...

  7.21 m + 9 m + 9.42 m + 13 m = 38.63 m

The perimeter of the figure rounded to 2 decimal places is 38.63 meters.

Answer:

Depends. See below.

Step-by-step explanation:

Let's take 1*-2 for example. If we multiplied 1 with -2, the resulting product will be negative since it's -2. Now if we did -1*-2, then the resulting product will be positive since it's 2.

Answer:

Distance = 660 meters

Step-by-step explanation:

Given the following data;

Radius, r = 21 m

Number of revolutions = 5 times

To find the distance covered;

The distance covered in one revolution is given by the circumference of a circle.

Mathematically, circumfeence of a circle is equal to;

C = 2πr

Substituting into the formula, we have;

C = 2 * 22/7 * 21

C = 44 * 3

C = 132 meters

Next, we find the distance covered;

Distance = Circumference * Number of revolutions

Distance = 132 * 5

Distance = 660 meters

Answer:

A mixed number is a whole number plus a fractional part. An improper fraction is a fraction where the numerator (top number) is larger than the denominator (bottom number). You can convert between mixed numbers and improper fractions without changing the value of the figure.

Answer:

x = 43

Step-by-step explanation:

The two angles add to 93

x+ 50 = 93

Subtract 50 from each side

x+50-50 = 93-50

x = 43

Answer:

x = 43 °

Step-by-step explanation:

sum of two angles is equal to 93°,

50 ° + x = 93 °

Subtract 50° from each side

50° - 50° + x = 93° - 50°

x = 43°
