Observing the histogram, frequency proportions, and normal probability plot based on the data set, below, of weights of hummingbirds (in grams) randomly selected from a population, we have a strong indication that the weights of the population of these hummingbirds from which these data were drawn are:

Answer:

24x-12y=0

6x-3y-5=0

a1/b1  = 4

a2/b2 =4

a1/b1 = b1/b2 ≠ c1/c2

∴ The pair of linear equations in two variables is said to be inconsistent and do not have any solution.

Answer:

Domain of a function means the set of values of the variable for which the given function exists.

(g circle f) (x) means g{f(x)}.

g{f(x)} will exists for all the real values of x except x = 7 and that particular x for which f(x) = -3.

Hence the domain of g{f(x)} will be all real values except x = 7 and the x for which f(x) = -3

Answer:

B) $3.56

Step-by-step explanation:

The price of one egg: $1.69

The price of a slice of bacon: $1.49

The price of a glass of orange juice: $1.09

Sara buys 2 eggs, 1 slice of bacon, and 1 glass of orange juice.

(2 eggs x $1.69) + (1 bacon x $1.49) + (1 glass of oj x $1.09) =

($3.38) + ($1.49) + ($1.09) = $5.96

Next, add the total gotten with the sales tax.

Sales tax: $0.48

$5.96 + 0.48 = $6.44

Then, subtract the total from the $10 that she used to pay:

$10 - 6.44 = $3.56

B) $3.56 is your answer.

~

Answer:

3.56

Step-by-step explanation:

because first, you 1.69$ dollars 2 times since your ordering it 2 times which gets you 3.38 $ next you add 1.49$ dollars because that's what a slice of bacon cost, then add1.09 since that's what a cup of orange juice cost. Then add  0.48 cents because that's the sale tax, at the end when you add everything up you get 6.44$ then subtract that from 10.00, then you get your answer!

Answer:

Step-by-step explanation:

distance = speed x time

? = 30 x 45

distance = 1350

Answer:

The answer is

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A (-2, 4) and B (-6, -7).

The distance between them is

[tex]d = \sqrt{ ({ - 2 + 6})^{2} + ({4 + 7})^{2} } \\ = \sqrt{ {4}^{2} + {11}^{2} } \\ = \sqrt{16 + 121} \\ = \sqrt{137} \: \: \: \: \: \: \: \: \: \: [/tex]

Step-by-step explanation:

Hey there! I'm happy to help!

To find the area of a triangle you multiply the base by the height.

We see that our base is 5 units long because it stretches from -6 to -1 on the coordinate plane. Our height is 8 because the y value goes from 3 to -5.

To find the area of a triangle, you just multiply the base by the height then divide by 2.

5(8)=40

40/2=20

The area is 20 square units.

Have a wonderful day! :D

im not sure what unit analysis is, but you would multiply 8 and 86. kilometer per hour. soo yeah lol 8×86=688. you would be able to travel 688 kilometers. you Don't have to give me brainliest lol but I hope that this helps :)

Answer: Choice B

If you lower your rates by 6% you will increase the number of occupancies by 12%

========================================================

Explanation:

Price Elasticity of Demand is found by dividing the percent change of demand over the percent change in price

[tex]\text{Price Elasticity of Demand} = \frac{\% \text{ change in demand}}{\% \text{ change in price}}[/tex]

If the price drops 6% leads to a 12% increase in demand, then we get this elasticity

[tex]\text{Price Elasticity of Demand} = \frac{\% \text{ change in demand}}{\% \text{ change in price}}\\\\\text{Price Elasticity of Demand} = \frac{12\% \text{ increase in demand}}{6\% \text{ drop in price}}\\\\\text{Price Elasticity of Demand} = \frac{12\%}{-6\%}\\\\\text{Price Elasticity of Demand} = \frac{0.12}{-0.06}\\\\\text{Price Elasticity of Demand} = -2\\\\[/tex]

The absolute value of that result is 2. We work backwards going from 2 to see the relationship between the 12% and 6%.

Answer:

Step-by-step explanation:

Answer:

The coordinates of Z is (-8,12)

Step-by-step explanation:[tex]\frac{2+x^{2} }{2}= -3 \\\frac{8+y^{2} }{2} = 10[/tex]

You multiply -3 by 2 to get -6 then multiply 10 by 2 to get 20

then you create the equations [tex]2+x^{2} =-6\\8+y^{2} =20[/tex] you subtract 2 by -6 and you get -8 (x coordinate) and you subtract 8 by 20 to get 12 (y coordinate)

To check your answer you use the Midpoint formula [tex](\frac{x^{1}+ x^{2} }{2} )(\frac{y^{1}+y^{2}}{2}) =M[/tex]

[tex]\frac{2+-8}{2} =\frac{-6}{2} = -3\\\frac{8+12}{2} =\frac{20}{2} =10[/tex] and you get your midpoint.

Answer:

Step-by-step explanation:

This question bothers on permutation since we are to select a some people out of a group of people and then arrange in a straight line. If r object are to be arranged in a straight line when selecting them from n pool of objects. This can be done in nPr number of ways.

nPr = n!/(n-r)!

Selection of 6 people out of 8 people can therefore be done in 8C6 number of ways.

8P6 = 8!/(8-6)!

8P6 = 8!/2!

8P6 = 8*7*6*5*4*3*2!/2!

8P6 = 8*7*6*5*4*3

8P6 = 56*360

8P6 = 20,160

Hence this can be done in 20,160 number of ways

Answer:

36.43

Step-by-step explanation:

In normal distribution(z) tomato plants have a height of less than 2.58 feet is 1.017%.

The normal distribution is a "continuous probability distribution that its symmetrical around its mean with most values near the central peak".

According to the question,

The heights of tomato plants are Normally distributed.

Mean(μ) = 3.56

Standard deviation (σ)  = 0.25

For a tomato plant that has a height of 2.98 feet

In order to find the Percentage of tomato plantof s have a height less than 2.98 feet

Standard Normal Distribution Formula,

z = (x-μ)/σ    where X~(μ,σ).

( 2.98 - 3.56 ) / 0.25  =-0.58 / 0.25  = -2.32.

P ( x < 2.58 ) = P( z < -2.32 )

                     = 0.01017( Using standard Normal distribution table)

Find the percentage of tomato plants with have a height of fewer than 2.58 feet is

Multiply 0.01017 by 100

= 0.01017 x 100 %

= 1.017%

Hence, using Standard Normal distribution we find tomato plants have heights less than 2.58 feet is 1.017%
