Answer:

5

Step-by-step explanation:

Use the Pythagorean Theorem

a²+b²=c² plug in the info you have

a²+12²=13² (c is always the side opposite from the right angle)

Solve for a

a²+144=169

   -144  -144

a²=25   take the square root of both sides

√a²=√25

a=5

Answer:

$4

Step-by-step explanation:

let t represent teddy bear and v represent vase, then

2t + 3v = 27 → (1)

3t + 2v = 30.5 → (2)

Multiplying (1) by 3 and (2) by - 2 , then adding will eliminate t, that is

6t + 9v = 81 → (3)

- 6t - 4v = - 61 → (4)

Add (3) and (4) term by term to eliminate t, that is

5v = 20 ( divide both sides by 5 )

v = 4

The cost of the flower vase is $4

It is going to be $4.00

Answer:

The are 21 roses in the bouquet

Step-by-step explanation:

Since the 49 roses are distributed evenly amongst the 7, then what each of the seven will get would be 49/7 = 7 roses

So 3 of the friends combine every of theirs to make a bouquet

The number of roses in the bouquet will be 7 + 7 + 7 = 21 roses

Answer:

Sometimes

Step-by-step explanation:

I’ll give you an example so you can understand:

Let’s say x is 4. So plug 4 into the problem:

|4|=4  →  This is a very true statement, where the absolute value of 4 is equal to 4.

Now, let’s say x is -7. So plug -7 into the problem:

|-7|=-7  →  This is a false statement because it’s saying that the absolute value of -7 is -7 which is very untrue.

So |x|=x only works for positive numbers, but not negative numbers. Therefore, |x|=x is the absolute value of x sometimes.

Hope this helps and answers your question! :)

Answer:

[tex]h=\frac{h_{m}-h_{t}+44.145}{3}t-4.905t^{2}+h_{t}[/tex]

(if the heights are measured in meters)

Step-by-step explanation:

In order to solve this problem we will need to first draw a diagram of the situation (see attached picture) and then, make use of the following physics equation:

[tex]y_{f}=\frac{1}{2}at^{2}+v_{0}t+y_{0}[/tex]

where:

[tex]y_{f}[/tex]=height of the object at a given time t

a=acceleration due to gravity

t=time

[tex]v_{0}[/tex]=initial velocity of the object

[tex]y_{0}[/tex]=initial height of the object.

we know most of this data, except for the height of theh object at the given time t and the initial velocity of theh object. We can make use of the given time to write the velocity in terms of the height of thte tree and the height of the monolith.

So let's substitute the values we know so far:

[tex]h=\frac{1}{2}(-9.81)t^{2}+v_{0}t+h_{tree}[/tex]

the problem tells us that after 3 seconds, the object reaches the height of the monolith, so let's do the substitution:

[tex]h_{monolith}=\frac{1}{2}(-9.81)(3)^{2}+v_{0}(3)+h_{tree}[/tex]

we can now solve this equation for the initial velocity, so we get:

[tex]h_{monolith}-h_{tree}=-44.145+3v_{0}[/tex]

[tex]h_{monolith}-h_{tree}+44.145=3v_{0}[/tex]

so:

[tex]v_{0}=\frac{h_{monolith}-h_{tree}+44.145}{3}[/tex]

and now we can substitute this back into the original formula to get the equation that represents the height of the coconut above the ground after t seconds:

[tex]h=\frac{h_{m}-h_{t}+44.145}{3}t-4.905t^{2}+h_{t}[/tex]

Answer:

Note: The full question is attached as picture below

a) Hо : p = 0.71

Ha : p ≠ 0.71

p = x / n

p = 91/110

p = 0.83.

1 - Pо = 1 - 0.71 = 0.29.

b) Test statistic = z

= p - Pо / [√Pо * (1 - Pо ) / n]

= 0.83 - 0.71 / [√(0.71 * 0.29) / 110]

= 0.12 / 0.043265

= 2.77360453

Test statistic = 2.77

c) P-value

P(z > 2.77) = 2 * [1 - P(z < 2.77)] = 2 * 0.0028

P-value = 0.0056

∝ = 0.01

P-value < ∝

Reject the null hypothesis.  There is sufficient evidence to support the researchers claim at the 1% significance level.

Answer:

120?

Step-by-step explanation:

Let's solve the problem step by step: Let's assume the other number is x. According to the problem, the sum of the two numbers is 240. so we can write the equation as: [tex]x + y = 240[/tex]

To find the value of x, we need to substitute the value of y into the equation. Since y is given, we can substitute it. [tex]x + y = 240 x + y = 240 x + y + (-y) = 240 + (-y) x = 240 - y[/tex] Now, we have an equation expressing x in terms of y. To determine the value of x, we need to know the value of y.

Without that information, we cannot calculate the value of x specifically. However, based on the information given, we can conclude that the value of x will be equal to 240 subtracted by the value of y.

Step-by-step explanation:

Line e parallel to line g. Therefore, option A is the correct answer.

Parallel lines are those lines that are equidistant from each other and never meet, no matter how much they may be extended in either directions.

Given that, in a plane line e is parallel to line f line f is parallel to line g and line h is perpendicular to line e.

Since, e║f, f║g

So, e║g

Therefore, option A is the correct answer.

Answer:

The Mean absolute deviation of any data set is best for explain how spread out the data values are compared to each other and the mean. This value is found be finding the difference of all data points to the mean of the data set, and then finding the average of those, by adding them all up and dividing by the total number of data points there are. If the mean absolute deviation is larger, then this means that there is more variability in the data set, and it is in fact very spread out. Finding the average of the distances of data points from the mean can be very helpful in determining conclusions about data sets.

Step-by-step explanation:

The Mean absolute deviation of any data set gives us an idea about the variability in a dataset.

The mean absolute deviation of a dataset is the average distance between each data point and the mean.
