Please find the missing side of the triangle and round the answer to the nearest tenth. Thanks.

Answer:

B

Step-by-step explanation:

The range is all values of y. Y goes from -1 to 1. Please mark brainliest.

Answer:

see below

Step-by-step explanation:

The domain of the function is the possible x values

The domain is all real values since x can be any number

The range of the function is the possible y value

The values of y go from -1 to 1 so

-1 ≤y≤1

Answer:

  θ = {0, π/2, π, 3π/2, 2π} . . . . choice B

Step-by-step explanation:

In this equation, r will be a maximum where cos(4θ) is a maximum. That is where ...

  4θ = 2kπ . . . . for some integer k

Dividing by 4 gives ...

  θ = k(π/2)

  θ = {0, π/2, π, 3π/2, 2π} . . . . matches choice B

__

You will note that the graph also has extremes at odd multiples of π/4. These are the locations where cosine is a minimum and r is negative. It can be argued that r is not a maximum at those points.

Answer:

$84.80

Step-by-step explanation:

find the difference between accurate price and written price: 74 - 47 = 27

find written total (before Mrs. Taylor found mistake) by undoing the mean calculation: 82.55 x 12 = $990.60

the total expenses is $27 more than what they thought: 990.60 + 27 = 1017.60

divide accurate total by 12 to find mean: 1017.60 / 12 = $84.80

hope this helps :)

Answer:

0.13

Step-by-step explanation:

First let's find the probability of finding the first species or the second species:

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 0.61 + 0.08 - 0.28

P(A or B) = 0.41

Then, to find the probability of finding one or another but not both, we just need the symmetric difference of the events, that is: P(A or B) - P(A and B):

P(A or B) - P(A and B) = 0.41 - 0.28 = 0.13

Answer:

Part A. I chose points (7,1.3) and (48,9.8)

Part B. a. Positive correlation; b.  y = 0.21x - 0.2

Step-by-step explanation:

Part A.

I chose the first and last points on the line — (7 in, 1.3 lb) and (48 in, 9.8 lb).

That put three points on the line, three above it, and four below.

Part B

a. Type of correlation

There is a positive correlation between the length of a puppy and its weight.

You would expect a longer dog to be bigger and weigh more than a shorter dog.

b.  The equation for the line of best fit

The slope-intercept equation for a straight line is

y = mx + b

where m is the slope of the line and b is the y-intercept.

The line passes through the points (7,1.3) and (48, 9.8).

(i) Calculate the slope of the line

\begin{array}{rcl}

[tex]m & = & \dfrac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\ & = & \dfrac{9.8 - 1.3}{48-9}\\\\& = & \dfrac{8.5}{41}\\\\& = & \textbf{0.21 lb/in}\\\\\end{array}[/tex]

The slope of the line is 0.21 lb/in.

(ii) Locate the y-intercept

Put the slope and the coordinates of one point into the slope-intercept formula.

[tex]\begin{array}{rcl}y & = & mx + b\\1.3 & = & 0.21\times7 + b\\1.3 & = & 1.47 + b\\b & = & -0.2\\\end{array}[/tex]

The y-intercept is at (0,-0.2)

(iii) Write the equation for the line

y = 0.21x - 0.2

Answer:

Graphed below.

Step-by-step explanation:

The slope of the line is -1/3.

The x-intercept is at (6, 0).

Answer:

Height = 8 yards, base = 15 yards.

Step-by-step explanation:

Let the height be x yards then the base = x+7 yards.

Area  = 1/2 * base * height, so:

1/2 * (x+7) * x = 60

1/2x(x + 7) = 60     Multiply through by 2:

x(x + 7) = 120

x^2 + 7x - 120 = 0

(x - 8)(x +15) = 0

x = 8, -15

x = 8. ( we ignore the negative root).

So the base is 8+7 = 15 yards long.

The correct answer is 20.7 inches of snow

Explanation:

The chart registers the total of snowfall at the school, in this, you can observe the total of snow in December was 3.4 inches, while in January the total was 12.3 and in February it was 8.4. Additionally, if you want to know the total during January and February combined the correct process is to add the two numbers. This means 12.3 inches (January) + 8.4 inches (February) = 20. 7 inches (Total in January and February.) Thus, the answer is 20.7 inches of snow.

Answer:

[tex]y=3t^9+C[/tex]

Step-by-step explanation:

Given:  [tex]\dfrac{dy}{dt}=27t^8[/tex]

We want to obtain the general solution of the given differential equation.

[tex]dy=27t^8$ dt\\$Take the integral of both sides\\\int dy =\int 27t^8$ dt$\\y=\dfrac{27t^{8+1}}{8+1} +C$, (where C is the constant of integration)$\\y=\dfrac{27t^{9}}{9} +C\\\\y=3t^9+C[/tex]

The general solution of the differential equation is: [tex]y=3t^9+C[/tex]

CHECK:

[tex]\dfrac{d}{dt} y=\dfrac{d}{dt}(3t^9+C)=\dfrac{d}{dt}(3t^9)+\dfrac{d}{dt}(C)\\\\\text{Since derivative of a constant is zero}\\\\\dfrac{dy}{dt}=27t^{9-1}\\\dfrac{dy}{dt}=27t^8[/tex]

Answer:

27°

Step-by-step explanation:

Let line AB be extended to touch line DC at point F, thereby forming triangle BCF.

∠ABC + ∠BCE = 180° (sum of interior angles in a transversal).

∠ABC + 48 = 180

∠ABC = 180 - 48 = 132°

Also in triangle ADF, ∠ADF + ∠DFA + ∠FAD = 180 (sum of angle in a straight line)

85 + ∠DFA + 25 = 180

∠DFA + 110 = 180

∠DFA = 180 - 110 = 70

∠DFA = 70

∠DFA + ∠BFC = 180° (sum of angle on a straight line)

∠BFC + 70 = 180

∠BFC = 180-70 = 110

∠BFC = 110°

∠ABC + ∠CBF = 180° (sum of angle on a straight line)

132 + ∠CBF = 180

∠CBF = 1800 - 132 = 42

∠CBF = 42°

In triangle BCF:

∠BFC + ∠CBF + x = 180° (sum of angle in a triangle)

42 + 110 + x = 180

x + 152 = 180

x = 180 - 152

x = 27°

Answer:

22 Degrees

Step-by-step explanation:

First, i extended the line AB, to make a triangle and then i found out that the angle is 70 degrees, and from that i got that the other angle is 110 degrees, so now i know that the triangle (that has X in it) is this formula:

110+48+X=180

so now 180-158=22, so that is the answer

Step 1: Find the area of the rectangle

A = lw

A = (29)13

A = 377

Step 2: Find the leg of the triangle

13 + 11 = 24

Step 3: Find the area of the triangle

A = 1/2bh

A = 1/2(24)(13)

A = 12(13)

A = 156

Step 3: Add the areas of the 2 figures together

377 + 156 = 533

Answer:

We need to remember that the Z value comes froma normal standard distribution given by:

[tex] Z\sim N(\mu=0,\sigma=1)[/tex]

So then the mean is 0 and all the values in the left are negative. So then if we want to analyze that if A is negative then  value of Z indicates that :

B. the number of standard deviations of an observation is to the left of the mean

Step-by-step explanation:

We need to remember that the Z value comes froma normal standard distribution given by:

[tex] Z\sim N(\mu=0,\sigma=1)[/tex]

And the z score formula is given by:

[tex]z=\frac{X -\mu}{\sigma}[/tex]

So then the mean is 0 and all the values in the left are negative. So then if we want to analyze that if A is negative then  value of Z indicates that :

B. the number of standard deviations of an observation is to the left of the mean

B. the number of standard deviations of an observation is to the left of the mean

A [tex]Z[/tex] score is a numerical measurement that describes a value's relationship to the mean of a group of values. The value of the [tex]Z[/tex] score tells you how many standard deviations you are away from the mean. A negative [tex]Z[/tex] score reveals the raw score is below the mean average. Also, a negative value of Z indicates that B. the number of standard deviations of an observation is to the left of the mean

Answer:

The probability is 40%

Step-by-step explanation:

a) There are ten pieces of paper with ten numbers

Probability of selecting four pieces of paper = 4/10 or 40%

Probability that the four numbers selected will have a sum greater than 82 = 82/205 = 40%

Therefore, the probability of selecting four numbers that have a sum greater than 82 out of ten numbers totalling 205 is 40%.

b) Probability is the ratio of the number of outcomes favourable for the event to the total number of possible outcomes.   In other words, it is a measure of the likelihood of an event (or measure of chance).
