what line is parallel to y=7x-4

Answer:

∠AOB = 112°

Step-by-step explanation:

mentally draw line segment OC

that line bisects 124° so ∠OCB = 1/2(124°) = 62°

ΔOCB is isosceles because OB = OC

∠OBC = 62° because it is equal to ∠OCB

all triangle interior angles add up to 180°

∠BOC = 180° - 62° - 62° = 56°

∠AOC = 56° because OC was a bisector of ∠AOB

∠AOB = 56° + 56° = 112°

Answer: The first and last table.

As the x increases by 2, the y goes down by 1, so both tables have the same rate of change which means they are the same function.

Tables 1 and 5 are equal.

Given are 5 tables in x and y with two values each.

We are to find out which two represent the same function.

As for every function, two points are given.

Let us compare the slopes of each function.

Slope=change in y coordinate/change in x coordinate

Table           Slope

I                 -0.5

2               -0.5

3               -0.5

4                 1

5                -0.5

Table 4 is eliminated now.

Though slopes are the same for 1 and 2,f(4) =8 and 5 different . Hence I and II cannot be the same.  Similarly for 2 different values are there in table 3,4,5.  Hence 3,4,5 cannot be pairwise equal.

We find that table I and table 5 have the same slope. Also when pairwise taken, (4,8) and (2,9) slope = -0.5

So table I = table 5

Hope this helps... Stay safe and have a great day/night!!! :D

Answer: True, with a dice probability calculator, you can easily find the various probabilities related to rolling a set of dice. A dice probability calculator can be used to determine the probability of rolling a certain number or set of numbers on one or more dice, as well as the probability of achieving specific combinations or sums of numbers. By entering the number of dice and the number of sides on each die, a dice probability calculator can calculate the probability of rolling any given combination of numbers. This can be useful in a variety of applications, such as games of chance, statistical analysis, and simulations.

Answer:

Mean = 48

Median = 47.5

Range = 66

Step-by-step explanation:

to find the mean, you're going to add all the numbers up together and divide it by how many numbers there are. So in this case all the numbers add up to 480 And there are 10 numbers. So 480 / 10 is 48.

to find the median you need to find the middle number after putting these numbers in order.

15, 19, 28, 32, 43, 52, 66, 72, 72, 81

in this case there are an even amount of numbers so you need to find the two middle numbers which would be 43 and 52. You add those two numbers together and divide by 2 which would be 95 / 2 giving you 47.5.

to find the range you take the largest number which is 81 and subtract it from the smallest number which is 15 giving us the answer of 66.

Answer:

58= 2x +12

each pass is 23 dollars

Step-by-step explanation:

let x represent the cost of the passes

58= 2x + 12

solve for x

58-12 = 2x +12 -12

46 = 2x

46/2 =2x/2

23 = x

Answer: 29

Step-by-step explanation:

Answer:

D) x= square root of 89

Step-by-step explanation:

To find the missing side, use the equation a^2+b^2=c^2. You would plug 5 in for a to get 25 and 8 in for b to get 64. You would add those to get that 89 is equal to c^2 so you would get c by itself and and find that the answer is D. :)

16 unidades preparan simultáneamente 1200 empanadas por día.

Step-by-step explanation:

Si cada fuente tiene una capacidad de 75 empanadas por horneada y que la mayor cantidad posible ocurre cuando el volumen de producción se cocina simultáneamente, entonces el total de fuentes es la cantidad total de producción dividida por la capacidad de empanadas por fuente. Es decir:

\(x = \frac{1200\,emp}{75\,\frac{emp}{und} }\)

\(x = 16\,unidades\)

16 unidades preparan simultáneamente 1200 empanadas por día.

The dot product can be used to determine if the vectors v = 4i + j and w = i - 4j are parallel, orthogonal, or neither.The formula for the dot product of two vectors, v and w, is(v1 * w1) + (v2 * w2) = v w

Here, v1 equals 4, v2 equals 1, w1 equals 1, and w2 equals -4. How about we compute the dot product?v · w = (4 * 1) + (1 * -4) = 4 - 4 = 0

Two vectors are orthogonal (perpendicular) to one another if their dot product is zero. We can infer that the vectors v = 4i + j and w = i - 4j are orthogonal because their dot product is zero.Consequently, the appropriate response isThe orthogonal

The probability that the 3rd patient with heart failure that enters the emergency room is the first one due to outside factors is 0.02712.

Probability of natural occurrences = 0.82Probability of outside factors = 0.18To find the probability that the 3rd patient with heart failure that enters the emergency room is the first one due to outside factors, we have to consider two possibilities:

The first two patients are due to natural occurrences, or the first two patients are due to outside factors.If the first two patients are due to natural occurrences, the probability of the third patient being the first due to outside factors is:0.82 x 0.82 x 0.18 = 0.12272

If the first two patients are due to outside factors, the probability of the third patient being the first due to outside factors is:0.18 x 0.82 x 0.82 = 0.12272

Therefore, the total probability of the third patient being the first due to outside factors is the sum of these two probabilities:0.12272 + 0.12272 = 0.24544But, we have counted the case where all three patients have outside factors twice, so we need to subtract that probability once:0.24544 - 0.01836 = 0.22708

Therefore, the probability that the 3rd patient with heart failure that enters the emergency room is the first one due to outside factors is 0.22708 or approximately 0.02712.

Answer:

Step-by-step explanation:

If the wax was priced at $1.67 per square foot, it would cost $1,664.99 to wax the entire floor. The right answer is C.

The floor is made up of a trapezoid and a rectangle.

The area of a trapezoid can be calculated as:

A = (b₁ + b₂)/2 x h

Where b₁ and b₂ are the lengths of the bases and h is the height.

The trapezoid is 14 feet tall, and its bases are 33 feet long and (28 - 19) or 9 feet wide. Thus, its area is:

A = (33 + 9)/2 x  14

A = 294 square feet

The rectangle is 37 feet tall with a 19-foot base. Thus, its area is:

A = 19 x 37

A = 703 square feet

The area of the triangle and trapezoid together make up the overall area of the figure.

A = 294 + 703

A = 997 square feet

Finally, to find the cost of the wax, we multiply the area by the cost per square foot:

Cost = 997 * $1.67

Cost  = $1664.99

Using Marked recapature formula for estimation on population size we get,

the estimate for total population size is 1200.

Marked recaputure Method :

first step is to capture and mark a sample of individuals. The assumption behind mark-recapture methods is that the proportion of marked individuals recaptured in the second sample represents the proportion of marked individuals in the population as a whole. In algebraic terms,

R/S = M/N

where R --> second time marked

S---> size of sample second time

N --> estimate population size

M ---> Marked in start point

We have given that ,

Total marked turtles by researchers (M) = 800

Second time total sample size (S) = 300

second time marked turtles(R) = 200

we have to find out estimate for total population size .

For this , Mark -Recapture method is very efficient to calculate estimate for total population size.

putting all known values in above formula we get, R/S = N/M

=> 200/300 = 800/N

=> 800× 300 = N× 200

=> N × 200 = 240000

=> N = 240000/200

=> N = 1200

so, the estimate for total population size is 1200.
