The probability they choose a black and a brown puppy is 0.2857 (option B)
What is the probability?Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability they choose a black and a brown puppy = (number of black puppies / total number of puppies) x ( (number of brown puppies / total number of puppies - 1)
3/7 x 4/6 = 0.2857

When the ball leaves fingers x = 0 :
a) -1/25 ( 0-10)^2 + 11 = 7 ft
b) max height will be at - b/2a
-1/25 ( x^2 -20x +100 ) + 11 <====expand
-1/25 x^2 + 4/5x +7 a = -1/25 b= 4/5
then - b/2a = - 4/5 / (2* -1/25) = 10=x
sub in this value of x into the equation to find max height = 11ft
c) when x = 15
-1/25 ( 15-10)^2 + 11 = 10 ft

Of the songs in Brianna's music library, 1/3 are rock songs. Of the rock songs, 7/10 feature a guitar solo. What fraction of the songs in Brianna's music library are rock songs that feature a guitar solo?
Answer:
7/30 of her music library
Step-by-step explanation:
We are looking for 7/10 of 1/3. In this case this "of" means we will multiply the two fractions. To multiply fractions, we multiply
top × top
and
bottom × bottom
1/3 × 7/10
is 1×7 on top, and
3×10 on the bottom.
= (1×7)/(3×10)
= 7/30
7/30 cannot be simplified, so that is the answer.
Landon is lying in the grass looking at the top of a tree that is 200 m away. The angle of elevation between Landon's head and the top of
the tree is 36 degrees.
What is the height of the tree?

200 m
The height of the tree which is the opposite side of the right triangle is 145 meters.
How to find height when given angle of elevation?The angle of elevation is 36 degrees.
The situation forms a right angle triangle.
Therefore,
base of the triangle = 200 m
Hence, using trigonometric ratios,
tan 36 = opposite / adjacent

Option D is correct.
Figures are missing in the question.
The images below shows the missing figures of question.
Solution:For congruent figures, we need the same shape, same area, and inverse direction.
Congruent figures have congruency. That seems simple enough, but congruent figures need not be turned the same way or face the same direction to be congruent.
In the case of geometric figures, line segments with the same length are congruent and angle with the same measure are congruent.
In elementary geometry the word congruent is often used as follows. The word equal is often used in place of congruent for these objects.
In this sense, two plane figures are congruent implies that their corresponding characteristics are "congruent" or "equal" including not just their corresponding sides and angles, but also their corresponding diagonals, perimeters, and areas.
The figure in option D satisfies all these conditions. Hence, Option D is correct.

For the following exercises, determine whether each of the following relations is a function.
1. y = 2x + 8
Answer:
The relation y=2x+8 is a function because the two different output values of the function have the one unique input value.
Step-by-step explanation:
The given relation is y=2x+8.
It is required to determine the relation is a function.
This solution can be obtained by using the concept of function. First write the given relation y=2x+8 and determine whether the given relation is a function.
Step 1 of 1
The given relation is y=2x+8.
This relation shows that the two different output values of the function have one unique input value and this relation is a linear function.
Hence, the relation is a function.

49 2/10 x 7 1/5 = 980 / 10 x 36/5 = 35280 / 50 = 3528 / 5

using a bit of greek and latin roots, we can observe that all 3 terms have the same suffix of nomial in them. From this, we know that mono means one, bino means two, and tri means 3. Fun fact, there's also polynomial (if you did or didn't know), which is multiple terms more than 3.
Determine whether the given relation is an implicit solution to the given differential equation. Assume that the relationship does define y implicitly as a function x and use implicit differentiation.

We cannot express the function [tex]x^{2} -sin(x+y)=1[/tex] in y=f(x) form it has an implicit function.
Given function [tex]x^{2} -sin(x+y)=1[/tex] and dy/dx=2x sec(x+y)-1
A relation is said to be an implicit solution of a differential equation involving x,y and derivatives of y with respect to x if defined explicit solution. In other words the function which cannot be written as y=f(x).
Function is a relationship between two or more variables which have one value for each value of x.
We have to first differentiate the function with respect to x.
[tex]x^{2} -sin(x+y)=1[/tex]
2x-cos(x+y)(1+dy/dx)=0
2x-cos(x+y)+cos(x+y)dy/dx=0
cos(x+y) dy/dx=cos(x+y)-2x
dy/dx={cos(x+y)-2x}/cos(x+y)
dy/dx=cos(x+y)/cos(x+y)-2x/cos(x+y)
dy/dx=1-2x cos(x+y)
The given solution is incorrect.

Answer:
20 km rate should 7.76
Step-by-step explanation:
Definitions
The variable rate is the rate for every km.
The fixed rate is what is charged for someone just getting on their bicycle.
Givens
Length of race = 6 km
variable rate = 0.22 / km
fixed rate = x
Total cost = 4.68
Formula
Total cost = fixed rate + variable rate * distance
Solution
4.68 = 6*0.22 + x
4.68 = 1.32 + x Subtract 1.32 from both sides.
4.68 - 1.32 = 1.32 - 1.32 + x Combine
3,36 = x
The fixed rate is 3.36
Before getting the answer to the question asked, we should see if we get the same fixed rate for 24 km
Check
Total Cost = fixed rate + variable rate*distance
Total Cost = 8.64
fixed rate = x
variable rate = 0.22
distance = 24 km
8.64 = x + 0.22 * 24 Combine
8.64 = x + 5,28 Subtract 5.28 from both sides
8.54 - 5,28 = x + 5.28 - 5,28 Combine
3.36 = x which agrees with our first calculation for the fixed rate.
Answer
y = 3.36 + 20*0.22
y = 3.36 + 4.4 Combine
y = 7.76
A box had twice as many grapes as a basket. Once 2 kg of grapes were added to the basket, it contained 0.5 kg more than the box. How many kilograms of grapes are in the basket now? (it's not 3kg or 1.5kg)
Answer:
3.5kg
Step-by-step explanation:
Let original weight of grapes in box be X and weight of grapes in basket be Y.
From the first sentence
X = 2Y (weight in box = 2 times weight in basket) --- (1)
If you add 2kg of grapes to basket, the weight of grapes in basket = Y + 2
From the second statement
Y + 2 = X + 0.5
Subtracting Y from the LHS gives 2 = X - Y + 0.5
Subtracting 0.5 from both sides gives 2-0.5 = X - Y or X - Y = 1.5 --- (2)
Substituting for X from the first equation in (2) we get
2Y - Y = 1.5 or Y = 1.5kg
But this is the original weight of the grapes in the basket. Since we have added 2 kg of grapes to the original weight, we get the weight of grapes in basket now as 1.5 + 2.0 = 3.5kg
list the 8 numbers between 4 and 40 in a sequence of 10 numbers a common difference
Answer:
8, 12, 16, 20, 24, 28, 32, 36
Step-by-step explanation:
the nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
a₁ is the first term and d the common difference
given a₁ = 4 and a₁₀= 40 , then
4 + 9d = 40 ( subtract 4 from both sides )
9d = 36 ( divide both sides by 9 )
d = 4
add d to each term to obtain the next term
4 + 4 = 8
8 + 4 = 12
12 + 4 = 16
16 + 4 = 20
20 + 4 = 24
24 + 4 = 28
28 + 4 = 32
32 + 4 = 36
the 8 terms between 4 and 40 are
8, 12, 16, 20, 24, 28, 32, 36

Binomial distribution will be used to know the probability that the total weight of the samples will exceed 530 pounds.
It is given that the rocket that will return the rock and soil samples to Earth cannot lift off if the total weight of the samples from the rovers exceeds 530 pounds.
In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean-valued outcome: success (with probability p) or failure (with probability q = 1 − p). A single success/failure experiment is also called a Bernoulli trial or Bernoulli experiment, and a sequence of outcomes is called a Bernoulli process; for a single trial, i.e., n = 1, the binomial distribution is a Bernoulli distribution. The binomial distribution is the basis for the popular binomial test of statistical significance.
