Answer:

∴ x = 1, y = -3

Step-by-step explanation:

x - y = 4 ------ equation (1)

2x + y = 5 ------ equation (2)

Add equations (1) and (2):
(2x + y) + (x - y) = 5 - 4

    2x + y - x - y = 1

                   ∴ x = 1

Substitute x = 1 into equation (1):

1 - y = 4

  -y = 3

∴ y = -3

Answer:

See step by step explanation below

Step-by-step explanation:

x  -2  -1  0  1  2

y  7   8   9  10  11

The geom_jitter() function is the function creates a scatterplot and then adds a small amount of random noise to each point in the plot to make the points easier to find

Given that,

In order to make the points in the plot easier to find, function first creates a scatterplot and then adds a small amount of random noise to each point in the plot.

Generally, To make the points in the scatterplot easier to find, the geom jitter() method first builds a scatterplot and then adds a little amount of random noise to each point in the plot.

What is the purpose of the Geom jitter () function? Description. The geom point (position = "jitter") shortcut is the jitter geom. It is a practical method of managing overplotting brought on by discreteness in smaller datasets by adding a little degree of random variation to the location of each point.

The percentage of women who spend less than $190.00. Assume the variable is normally distributed is 0.0694 or 6.94%

Given that,

Women spend an average of $146 on a Saturday lunch, according to a national retail federation poll. Suppose $29.44 is the standard deviation.

To find : How many ladies or the percentage of ladies spend less than $190 on a Saturday lunch

P(X < 190) = P(x-μ/σ <  190 -146.21 /29.44)

                 = P(Z > 1.487)

                 = 0.0694

So, the proportion of female consumers who spend less than $190 and that the variable has a 0.0694 or 6.94% normal distribution.

For integral 2 15 e1/x dx. 1, the approximate value of T10 = 27.05 and M10 = 30.29

In this question, we need to find  the approximations T10 and M10 for 2 15 e1/x dx. 1

i.e., To find: Integral approximate using Trapezoid rule and midpoint rule

f(x) = 15e^(1/x)

a = 1, b = 2, bx = 1/10

T10 = bx/2 [f(1) + 2f(1.1) + 2f(1.2) + 2f(1.3) + . . . + f(2) ]

      = 1/20[15e + 30e^(1/1.1) + 30e^(1/1.2) + . . . + 15e^(1/2)]

      = 1/20 * 30 [(e/2) + e^(1/1.1) + e^(1/1.2) + . . . + (e^(1/2) / 2)]

      = 1.5 * 18.0362

      = 27.05

Now we find M10

M10 = Δx [f(1.05) + f(1.15) + . . . + f(1.95)]

       = 1/10 [15e^(1/1.05) + 15e^(1/1.15) + . . . + 15e^(1/1.95)]

       = 15/10 [e^(1/1.05) + e^(1/1.15) + . . . + e^(1/1.95)]

       = 1.5 * 20.1909

       = 30.29

Therefore, for integral 2 15 e1/x dx. 1, the approximate value of T10 = 27.05 and M10 = 30.29

Answer:

3.45 hours. The closest answer option to this value would be (10/3), which is technically 3.3333 hours, but it is the closest correct option, by far.  3.333 hours would suggest the distance was 250 miles, not 259 (250/75) = 3.33333)

Step-by-step explanation:

Distance, D, is found by multiplying the speed (75 mph) times the time, x (in hours.  If distance is 259 miles, we can write:

   259 miles = (75 miles/hr)*x

Rearrange to find x  [divide both sides by (75 miles/hr):

x = (259 miles/(75 miles/hr)

Note the units:  miles cancel and hours moves to the top, leaving only hours, which is what we want.

(259 hours)/75 = 3.45 hours

Answer:

∠ D = 94°

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ CBY is an exterior angle of the triangle, then

∠ C + ∠ D  = ∠ CBY , that is

49° + ∠ D = 143° ( subtract 49° from both sides )

∠ D = 94°

The value of m on solving the equation 6 1/9m+ 3 1/3m = 28 1/3 is 3

We need to solve the equation

6 1/9m+ 3 1/3m = 28 1/3 for m

converting mixed fractions into improper fractions

55/9 m + 10/3 m = 85/3

Upon taking L.C.M.

55/9 m + 10x3/3x3 m = 85/3

(55 + 30)m/9 = 85/3

3 x 85m = 85 x 9

m = 3

Therefore, the value of m on solving the equation 6 1/9m+ 3 1/3m = 28 1/3 is 3

The probability that the first card is a face card and the second card is a diamond is 1/17.

Probability simply means the likelihood that a particular event will occur or take place.

Number of face cards = 12

Number of diamonds = 13

Total number of cards in a deck = 52

The probability of getting a face card is 12/52 = 3/13

The probability of getting the diamond will be 13/51

Therefore, the probability of the face card and diamond will be:

= P(face card) × P(diamond)

= 3/13 × 13/51

Step-by-step explanation:

because the line falls from left to right, the line has a negative slope. =)

Answer: Negative

Step-by-step explanation:

       This line is "going down the stairs," or starting from the upper lefthand side to the bottom righthand side. This means we have a negative slope.

     If you need to find the slope;

      We will use the "rise over run" method. Starting at (-2, 3) we will count 4 units down and three units right to (1, 1) for a slope of -4/3.

Step-by-step explanation:

a man is in a boat that is floating 175 feet from the base of a 200 foot cliff. what is the angle of depression between the cliff and the boat?

A boat is moving 175 feet from the base and a man is in the boat. The height of cliff is 200 feet. We need to find the angle between the cliff and the boat.

We have a right angled triangle where base is 175 ft and height is 200 ft.

We know that tan θ = opposite / adjacent

                             = 200 / 175

                So θ = tan ^-1 (200 / 175)

                So θ = 48.8 degree

A Venn diagram is a diagram that uses circles to show the relationships between things or finite groups of things. Intersecting circles have one thing in common, but non-intersecting circles  do not have these features.

Venn diagrams help visualize the similarities and differences between two concepts. They have long been recognized for their usefulness as educational tools.  Venn diagrams have been used as part of  introductory logic curricula and in elementary school planning around the world since the mid-20th century.

Venn diagrams help show how different concepts and elements intersect. At a glance, you can see how things are similar, how they differ, and where and how they overlap. The center of a Venn diagram (the intersection of two or more circles) often represents a connection or main idea that can be decomposed into  various other circles, and labels on the outer part are more common than labels in the center. is clear. .

The slope of the line m is -2 if the line passes through (4, -3) and (0, 5) the answer is -2.

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

From the graph:

(4, -3) and (0, 5)

The slope of the line m = (5+3)/(-4)
