The number of ways of selecting 7-cards with 2 hearts, 2 diamonds, 2 clubs, and 1 spade is 1,169,176.

A permutation is an act of arranging the objects or elements in order. Combinations are the way of selecting objects or elements from a group of objects or collections, in such a way the order of the objects does not matter.

A standard deck of 52 cards contains 13 cards with hearts, 13 with diamonds, 13 with clubs, and 13 with spades.

The number of ways of selecting 7-cards with 2 hearts, 2 diamonds, 2 clubs, and 1 spade will be

[tex]\rm Number \ of \ ways = \ ^{13}C_2 \times ^{13}C_2 \times ^{13}C_2 \times ^{13}C_1 \\\\Number \ of \ ways = 78 \times 78 \times 78 \times 13 \\\\Number \ of \ ways = 6,169,176[/tex]

The number of ways is 6,169,176.

The relationship that describes the measure of the inscribed angle and the measure of the intercepted arc is: 2(m∠JKL) = m(JL)

The inscribed angle theorem states in a circle, the measure of the angle that is inscribed is always half of the arc that is intercepted. Which means that the intercepted arc is twice the measure of the inscribed angle.

In the image given:

Using the normal distribution, it is found that there is a 0.0571 = 5.71% probability that the total weight exceeds the maximum weight.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

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

In this problem, we have that the parameters are given as follows:

[tex]\mu = 60, \sigma = 10, n = 10, s = \frac{10}{\sqrt{10}} = 3.1623[/tex]

The probability that the total weight exceeds the maximum weight is the probability of a sample mean above 650/10 = 65 kg, which is one subtracted by the p-value of Z when X = 65.

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

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{65 - 60}{3.1622}[/tex]

Z = 1.58.

Z = 1.58 has a p-value of 0.9429.

1 - 0.9429 = 0.0571.

0.0571 = 5.71% probability that the total weight exceeds the maximum weight.

The answer to 30*120 is 3,600

Answer:

30 times 120 equals 3600

Step-by-step explanation:

One thing that is really easy to use to multiply is a calculator (either online or a hand-held one). But here is how you can multiply without a calculator...

Set up an equation on a piece of paper like how it is shown right below...

  30

x 120

Then, times the last digit (so the zero) of the bottom number. (But it doesn't really matter what order you put them in). Then, times it by the last digit of the top number. So that would equal 0! So as shown below, you would put the answer like so...

  30

x 120

      0

Then, you do 0 (last digit of bottom number) times 3 (you keep going left of the top number's digits). So that would also equal 0.

   30

x 120

   00

     0

Then you add a zero below, since we are now moving on to the next number to the left of the last digit of the bottom number (hopefully this is making sense). Then you do the exact same thing.

   30

x 120

   00

 600

Now that we're done with that, we add two zeros this time, since we are in the hundreds now. So it is to the next number now! (1) And then we do the exact same thing again!

   30

x 120

   00

 600

3000

Alright, that's done! Now we add all those answers together (0+600+3000)

And that gives us our answer! 3600!

Hopefully that made sense! :)

60/100 * 75 & 0.60 * 75

60% can be rewritten as 0.60, and since 60/100=0.60, this expression is correct as well

The other two are incorrect because 0.60/100 would be 0.6%, and 60*75 would mean she is saving 6000%

The sine of the other acute angle is 15/17 if the cosine of one acute angle of a right triangle is 8/17.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a cosine of one acute angle of a right triangle is 8/17.

Let's suppose the angle is α

[tex]\rm Cos\alpha = \frac{8}{17}[/tex]

As we know the cos is the ratio of adjacent to hypotenuse and Sin is the ratio of the opposite to hypotenuse.

Let's suppose the length of the hypotenuse is x units

From the Pythagoras theorem:

[tex]\rm 17^2=x^2+8^2[/tex]

x = 15 units

Now the Sin ratio:

[tex]\rm Sin\alpha = \frac{15}{17}[/tex]

Thus, the sine of the other acute angle is 15/17 if the cosine of one acute angle of a right triangle is 8/17.

Answer:

45 degree angle

Answer:

a_n = 9n - 11

Step-by-step explanation:

Explicit rule for an arithmetic sequence is a_n = a_1 + (n-1) d

a_1 is the first term of the sequence

d is the common difference. To find d you pick a number in the sequence and subtract it by the previous number. For example, 7 - (-2) = 9

16 - 7 = 9 so, d = 9

a_1 = -2 since it is the first term. Now substitute these numbers into the formula.
a_n = -2 + (n-1)(9)

And then we simplify.
9 • n = 9n

9 • -1 = -9
Then we’ll have a_n = -2 + 9n -9 and well simplify even further.
-2 -9 = -11

So we get

a_n= 9n -11

the step equation because of the font

The product of the two equation in which one is binomial equation another quadratic equation,  is 12a³+2a²+23a+18.

To multiply the two equation, each term of the first equation is multiples from the second term.

The first equation given in the problem is,

[tex]3a+ 2[/tex]

The second equation given in the problem is,

[tex]4a^2 -2a+ 9[/tex]

The product of these two equations are,

The radius of the cone that holds ice cream which has height of 4.5 inches and 1.5π cubic inches, is 1 inches.

Volume of cone is the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.

The volume of the cone can be given as,

Here, (r) is the radius of the base of the cone and (h) is the height of the cone.

The diagram of the cone is shown, in which,

Let suppose the radius of the cone is r inches long. Thus, put the values in the above formula,

[tex]V=\dfrac{1}{3}\pi r^2h\\1.5\pi=\dfrac{1}{3}\pi r^2(4.5)\\1.5\pi\times3=\pi r^2(4.5)\\\dfrac{1.5\pi\times3}{\pi \times 4.5}= r^2\\1= r^2\\r=\sqrt{1}\\r=1\rm\; inches[/tex]
