Answer:

Step-by-step explanation:

Multiply to find the total weight of all the bars in grams.

Then convert to kilograms.

There are 1,000 grams in a kilogram.

To get the correct answer, first multiply to find the total weight of all the bars in grams.

6 × 32 = 192 g

Then convert to kilograms.

192 g ÷ 1,000 = 0.192 kg

Answer:

Two transformations or series of transformation that support Maria's claim and Maps ΔABE to ΔACD are;

A dilation with a scale factor of 3 about point A

A dilation with a scale factor of 3 about point B followed by a translation of 4 units downwards

Step-by-step explanation:

Using an online source, we have;

ΔABE ~ ΔACD

The coordinate of triangle ΔABC are;

A(-6, 4), B(-6, 2), and E(-2, 2)

The coordinate of triangle ΔACD are;

A(-6, 4), C(-6, -2), and D(6, -2)

∠A ≅ ∠A by reflexive property

Segment BE ║Segment CD and segment DE and segment AE are collinear on transversal AD

∴ ∠E ≅ ∠D Corresponding angles

∴ ΔABE ~ ΔACD by Angle-Angle rule of congruency

Segment AB on ΔABE and segment AC on triangle ΔACD are corresponding sides on both triangles

The length of segment AB on ΔABE = 2 units

The length of segment AC on ΔACD = 6 units

The scale factor of dilation, SF = (The length of segment AC)/(The length of segment AB)

∴ SF = (6 units)/(2 units) = 3

Therefore, ΔABE maps to ΔACD by either of the following;

1) A dilation with a scale factor of 3 about point A

2) A dilation with a scale factor of 3 about point B followed by a translation of 4 units downwards.

Answer:

Her monthly payment is approximately $4,611.65

Step-by-step explanation:

The monthly payment on the loan is given by the following formula;

[tex]A = P \cdot \dfrac{r\cdot (1 + r)^n}{(1 + r)^n - 1}[/tex]

A = The monthly payment

P = The principal amount = $423,000

r = 5.65%

The number of years = 10 years

[tex]A = 423,000 \cdot \dfrac{\dfrac{0.0565}{12} \cdot \left (1 + \dfrac{0.0565}{12} \right )^{180}}{\left (1 + \dfrac{0.0565}{12} \right )^{180} - 1} \approx 4611.65[/tex]

Her monthly payment, A ≈ $4,611.65

Answer:

y = 3/4x -2

Step-by-step explanation:

Points on the graph: (4, 1) and (0, -2)

Slope:

m=(y2-y1)/(x2-x1)

m= (-2-1)/0-4)

m=(-3)/(-4)

m = 3/4

Point-slope:

y - y1 = m(x - x1)

y - 1 = 3/4(x - 4)

y - 1 = 3/4x - 3

y = 3/4x -2

Answer:

$ 100 is saved by paying the total amount at the time of purchase

Step-by-step explanation:

its Originally 800 but You put down 200 leaving it At 600 But 50 time 10 is 500 plus 200 more Because you pay 200 more for the last 4 months So 500 plus 200 is 700 plus the 200 you put down And it would be 900 instead of 800

Answer:

-8.45, 0.95, 8.25

Step-by-step explanation:

The easiest way to do this is to convert the fraction to a decimal, and then compare the values.

8 8/32 is equal to 8 and 1/4. Because 1/4 = 0.25, 8 and 8/32 equals 8.25.

Now, let's compare values.

Numbers we need to compare: -8.45, 0.95, 8.25

The smallest number is -8.45, then 0.95, and lastly, 8.25.

Thus the answer is

-8.45, 0.95, 8.25

Answer:

$756.00

12.60 x 60 = $756.00

Answer:

Step-by-step explanation:

You should add the weights of each kitten and then divide by the number of kittens. Ex. There are 5 kittens weighing 2, 1, 3, 2, and 2. So you would add those to get 10 and divide by the number of kittens which is 5 to get an average of 2.

So in this case you would first add the weight of the kittens

Then divide that by the number of kittens

Then the quotient would be the average of the weight of the kittens in the shelter.

Answer:

Explained below.

Step-by-step explanation:

There are quite a few examples of this but I will go with what is common in physics which is "acceleration due to gravity".

Acceleration due to gravity is positive when an object is falling down in the direction of gravity but negative when it is thrown upwards and acting against gravity motion.

Thus;

g_downwards = 9.8 m/s²

g_upwards = -9.8 m/s²

If acceleration due to gravity is zero, it means that the object is at the centre of the earth because at that point g = 0.

Answer:

here you go

Step-by-step explanation:

Answer:

a) 0.7639 = 76.39% probability that at least 3 passengers will have been stopped due to change in their pockets.

b) 0 is less than 2.5 standard deviations from the mean, so it would not be unusual.

Step-by-step explanation:

For each passenger, there are only two possible outcomes. Either they will have been stopped due to a change in the pocket, or not. Passengers are independent. This means that we use the binomial probability distribution 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.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

A measure is considered unusual if it is more than 2.5 standard deviations of the mean.

25% chance that the cause is change in the passenger's pocket.

This means that [tex]p = 0.25[/tex]

During a given hour, 15 passengers are stopped because of a signal from the metal detector.

This means that [tex]n = 15[/tex]

a) Find the probability that at least 3 passengers will have been stopped due to change in their pockets.

This is

[tex]P(X \geq 3) = 1 - P(X < 3)[/tex]

In which

[tex]P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]

So

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

[tex]P(X = 0) = C_{15,0}.(0.25)^{0}.(0.75)^{15} = 0.0134[/tex]

[tex]P(X = 1) = C_{15,1}.(0.25)^{1}.(0.75)^{14} = 0.0668[/tex]

[tex]P(X = 2) = C_{15,2}.(0.25)^{2}.(0.75)^{13} = 0.1559[/tex]

[tex]P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0134 + 0.0668 + 0.1559 = 0.2361[/tex]

[tex]P(X \geq 3) = 1 - P(X < 3) = 1 - 0.2361 = 0.7639[/tex]

0.7639 = 76.39% probability that at least 3 passengers will have been stopped due to change in their pockets.

b) If 15 passengers are stopped by the detector, would it be unusual for none of these to have been stopped due to change in the pocket

First we find the mean and the standard deviation:

[tex]E(X) = np = 15*0.25 = 3.75[/tex]

[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{15*0.25*0.75} = 1.68[/tex]

3.75 - 2.5*1.68 = -0.45

0 is less than 2.5 standard deviations from the mean, so it would not be unusual.
