The probability of getting a 10 or a jack from a deck of poker cards (52 cards) is 15.38%.

Probability is concerning about numerical description  

Is how likely is an event is occur or how likely it is true.

As per the given sequence -

there are four 10 cards and  four jack cards respectively

4+4=8

If you want to get one from the  52 cards, so it's 8 out of 52. 8/52

To calculate the percentage, you must  multiply 8 by 100, then divide by 52.

Thus,

Answer:

B.  110°

Step-by-step explanation:

Vertical Angles Theorem

When two straight lines intersect, the opposite vertical angles are congruent.

Linear Pair

Two adjacent angles that sum to 180° (two angles which when combined together form a straight line).

Corresponding Angles Postulate

When a straight line intersects two parallel straight lines, the resulting corresponding angles are congruent.

Given:

Apply the Vertical Angle Theorem to find the measure of angle 8:

⇒  m∠3 = m∠8 = 70°

As angles 7 and 8 form a linear pair:

⇒  m∠7 + m∠8 = 180°

⇒  m∠7 + 70° = 180°

⇒  m∠7 = 110°

As line p is parallel to line q, apply the Corresponding Angles Postulate to find the measure of angle 15:

⇒  m∠15 = m∠7 = 110°

Therefore, the measure of angle 15 is 110°.

If  hose fills a hot tub at a rate of 3.49 gallons per minute. Then 1.64 hours will it take to fill a 343​-gallon hot​ tub

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given,

A hose fills a hot tub at a rate of 3.49 gallons per minute.

We need to find how many  hours will it take to fill a 343​-gallon hot​ tub

3.49/1=343/x

Apply cross multiplication

x=343/3.49

x=98.28 minutes

1 hr=60 minutes

So divide 98.28/60

By using slope intercept form of equation of line, the graph of

h(x) = [tex]-\frac{2}{5}x + 4[/tex] has been shown

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If  [tex]\theta[/tex]  is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

Let the independent variable be x and dependent variable be h(x)

The dependent variable decreases 2 units for every 5 units the independent variable increase.

Slope = [tex]-\frac{2}{5}[/tex]

So,

h(x) = [tex]-\frac{2}{5}x + c[/tex]

Now,

h(0) = 4

So, c = 4

h(x) = [tex]-\frac{2}{5}x + 4[/tex]

The distance traveled by train would be 300 miles.

What is the relation between speed, distance, and time?

You can use the equivalent formula d = rt which means distance equals rate times time. To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

A train travels for 3.75 hours at 80 miles per hour.

The distance traveled = speed * time

                                     = 3.75 * 80

To make this mixture 60% cashews, 240 pounds of cashews must be added to 36 pounds of this mixture.

For the stated question-

Let the total amount of mix be 'x'.

45% of the mix is cashew nuts: 0.45x.

Now, 60% cashews is made by making 36 lb; 0.60x.

Then, 0.45x + 36 = 0.6x

x = 36/0.15

x = 240

b) The alternative hypothesis is: [tex]H_1: p > 0[/tex]

c) The test statistic is: z = 9.71.

d) The correct option is of: A. Yes.

e) The confidence interval is of: 0.0819 < p < 0.1336.

At the null hypothesis, it is tested if there is not enough evidence that the proportion for men is greater, that is, the subtraction is not greater than 0:

[tex]H_0: p \leq 0[/tex]

At the alternative hypothesis, it is tested if there is evidence that the proportion for men is greater, that is, if the subtraction is greater than 0, hence:

[tex]H_1: p > 0[/tex]

We have a right-tailed test, as we are testing if the mean is greater than a value, with a significance level of 0.01, hence the critical value is of:

z = 2.327.

Thus the decision rule regarding the test statistic is given as follows:

For each sample, the mean and the standard error are given as follows:

Hence, for the distribution of differences, the mean and the standard error are given as follows:

The test statistic is given by the division of the mean by the standard error of the sampling distribution of the difference of sample proportions, hence:

z = 0.1078/0.0111 = 9.71.

z > 2.327 -> enough evidence that the proportion is greater.

The confidence interval is obtained as the mean plus/minus the multiplication of the standard error and of the critical value.

-8x-8 = -49.44+ 8x+12y=58.20

The total surface area of the solid object is the sum of the surface area of the cylinder and the surface area of the cone.

The surface area of the cylinder is 2πr(r+h), where r is the radius of the cylinder and h is its height.

The surface area of the cone is πr(l+r), where r is the radius of the cone and l is its slant height.

Since the cylinder and the cone have the same radius, we can call this radius r.

The total surface area of the solid object is therefore 2πr(r+h) + πr(l+r).

We are told that this total surface area is equal to 6336/210 = 30 sq. cm.

Thus, we can set up the equation: 2πr(r+h) + πr(l+r) = 30.

We are trying to find the value of l, which is the slant height of the cone. We are given the value of h, which is the height of the cylinder. We can substitute this value into the equation to get:

2πr(r+30) + πr(l+r) = 30.

This equation can be rearranged and solved for l to find the slant height of the cone.

l = sqrt(900 - 60r).

Since we are given that the slant height of the cone is 26 cm, we can substitute this value into the equation to solve for the radius of the cone:

26 = sqrt(900 - 60r)

Solving for r, we find that the radius of the cone is 15 cm.

Substituting this value back into the equation for the slant height of the cone, we find that the height of the cone is:

l = sqrt(900 - 60(15)) = sqrt(300) = 17.67 cm.

Thus, the height of the cone is approximately 17.67 cm.

The plane is perpendicular to the axis but does not go through the vertex. The plane intersects the double cone at only the vertex is ellipse.

A planar curve that has two focal points is normally called an ellipse on the condition that at every point on the curve, it will be seen that the sum of the two distances from the focal points is constant. This generalizes the shape of a circle, which is a unique variety of an ellipse whereby the two focus points coincide.

The plane is said to not be intersecting with the vertex, not parallel to the axis nor perpendicular to the axis, then not parallel to the side of the cone, but it intersects only one cone is called a circle.

A circle is defined as a closed, two-dimensional object whereby every point in the plane is seen to be equally spaced from a central point. The line of reflection symmetry is seen to be formed by all lines that transverse the circle. Additionally, every angle has rotational symmetry around the center.

b. The equation of the line that is perpendicular to the graph and intercepts the y-axis at (2,-2) is y = -1/m * x - 2

what is intercepts?

The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis.

a. The equation of the line that is perpendicular to the graph and intercepts the y-axis at (0, -6) can be written as:

                                    y = mx + b

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

Since the line is perpendicular to the graph, the slope of the line is the negative reciprocal of the slope of the graph. The y-intercept is (-6).

What is an area?

The measurement that expresses the size of a region on a plane or curved surface is called an area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

Here,

We take it that the semicircles cover the full width of the paper.

So the radius is 16/2 = 8 cm

Since there are two of them, the area is full circle.

First, we find the area of the rectangle before the cuts were made.

Area = L * W

L = 36

W = 16

Area = 36×16 = 576 cm²

Now, we find the area of the circle cutouts.

r = 8

Area = pi * r²

Area = 3.14 * 8²

Area = 3.14 * 64

Area = 200.96cm²

Now, we find the total area left

Total Area Left = rectangle - circle

Total Area Left = 576 - 200.96

Total Area left = 375.04cm².
