Answer:
1/52
Step-by-step explanation:
The probability that the card is a 4 in a pack of cards is 1 /13.
What is probability?A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
Given, A card is selected from a pack of 52 cards. A favorable outcome is getting 4 since there are four 4 in a pack of cards. Thus,
When a card is selected from a pack of 52 cards the number of possible outcomes is 52 i.e., the sample space contains 52 elements
Therefore there are 52 points in the sample space.
Let E be the event in which the card drawn is an ace.
Since there are 4 aces in a pack of 52 cards n(E)=4
∴P(E)= [tex]\frac{Totalnumberofpossibleoutcomes}{Numberofoutcomesfavourableto}[/tex]
E = [tex]\frac{n(S)}{n(E)}[/tex]
E = 4/52 = 1/13
Therefore, In a deck of cards, there is a 1 in 13 chance that the card is a 4.

What is a logarithm?The logarithm is exponentiation's opposite function in mathematics.
This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b. For instance, because 100 = 10², the logarithm of 100 in base 10 is 2, or log10 = 2.
Given, A logarithmic equation [tex]ln_ee[/tex], This in exponential form is, [tex]e^? = e[/tex].
We know, [tex]e^? = e[/tex], e to the what power should be e it should be 1.
Therefore, [tex]ln_ee = 1[/tex].
Similarly, [tex]log_{10}10[/tex] is 10 to the what power is 10 we know 10 to the power 1 is 10.
Therefore, [tex]log10[/tex] is 1.

A triangle is a shape with three sides and three angles. Types of triangles are isosceles triangle, equilateral triangle, scalene triangle, right angled triangle.
Two triangles are said to be congruent if all the corresponding three sides and three angles of one triangle is equal to the corresponding three sides and three angles of the other triangle.
Triangle SRV and triangle RQV are congruent triangles by side angle side congruency (i.e. SR = RQ, RV ≅ RV and ∠SRV = ∠QRV = 90°). Therefore:
SV = QV
4x - 1 = 15
4x = 16
x = 4 units
Triangle SRT and triangle RQT are congruent triangles by side angle side congruency (i.e. SR = RQ, TR ≅ TR and ∠SRT = ∠QRT = 90°). Therefore:
TQ = TS

Answer: (-3,3)
Step-by-step explanation:Answer: (-3,3)
Step-by-step explanation: P= IRT solve for T To solve for T, you must get T on it's own on one side of the equals sign, with all the other terms on the other side. IRT means that I and R are multiplied by T. To get rid of them we must do the opposite of multiply, which is divide. But because this is an equation, anything we do on one side of the equals sign, must be repeated on the other side. So if we divide the right side by IR, we must also divide the left side by IR

Answer:

Step-by-step explanation:
First you would write the equation 2+(-4)+8+(-6)
Now let’s solve starting from the left.
2+(-4) = -2
This is the equation so far: -2+8+(-6)
Then you would solve the right side 8+(-6) = 2
Now we have -2 + 2 which equals 0.
PS. You can also do in another way like 2-4+8-6. It’s the same method and concept.

A certain function h(x) contains the point (8,-2). Find the value of h^-1(-2) . Explain your answer.
Given:
A certain function h(x) contains the point (8,-2).
To find:
The value of [tex]h^{-1}(-2)[/tex].
Solution:
If a function is defined as
[tex]f(x)=\{(a,b):a\in R,b\in R\}[/tex]
Then, its inverse is defined as
[tex]f^{-1}(x)=\{(b,a):a\in R,b\in R\}[/tex]
It is given that, a certain function h(x) contains the point (8,-2). It means, its inverse [tex]h^{-1}(x)[/tex] contains the point (-2,8). So, the value of inverse function is 8 at x=-2, i.e.,
[tex]h^{-1}(-2)=8[/tex]
Therefore, the value of [tex]h^{-1}(-2)[/tex] is 8.

NEED HELP ASAP 30 POINTS
Answer:
88Step-by-step explanation:
Given the functions
f(x) = 3x² + x and g(x) = 2x
We are to find g(f(x))(-4)
First get g(f(x))
g(f(x)) = g(3x²+x)
Substitute x in g(x) with 3x²+x to have:
g(3x²+x) = 2((3x²+x))
g(3x²+x) = 6x² + 2x
Substitute = -4 into the result
g(f(x) (-4)) = 6(-4)² + 2(-4)
g(f(x) (-4)) = 6(16)-8
g(f(x) (-4)) = 96 - 8
g(f(x) (-4)) = 88
Hence the required answer is 88

Two cylinders are shown below. Find the volume of each cylinder. Use 3.14 for pie. Enter your answers rounded to the nearest hundredth.
Given:
For cylinder P: radius = 4.25 in. and height = 14 in.
For cylinder Q: radius = 7 in. and height = 8.5 in.
To find:
The volume of each cylinder.
Solution:
Volume of a cylinder is
[tex]V=\pi r^2h[/tex]
where, r is radius and h is height. Use 3.14 for [tex]\pi[/tex].
Using the above formula, the volume of cylinder P is
[tex]V_P=(3.14)(4.25)^2(14)[/tex]
[tex]V_P=794.0275[/tex]
[tex]V_P\approx 794.03[/tex]
Using the above formula, the volume of cylinder Q is
[tex]V_Q=(3.14)(7)^2(8.5)[/tex]
[tex]V_Q=1307.81[/tex]
Therefore, the volume of cylinder P is 794.03 sq. in. and volume of cylinder Q is 1307 sq. in.
The volume of cylinder P is 794.03 sq. in. and the volume of cylinder Q is 1307 sq. in.
What is the volume of a right circular cylinder?Suppose that the radius of the considered right circular cylinder be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
The given information is
For cylinder P:
radius = 4.25 in. and height = 14 in.
For cylinder Q:
radius = 7 in. and height = 8.5 in.
To find the volume of each cylinder.
The volume of a cylinder
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
where r is radius and h is height.
Using the above formula,
the volume of cylinder P
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
[tex]V = 3.14 \times (4.25)^2 \times 14 \: \rm unit^3\\\\V = 794.03[/tex]
The volume of cylinder Q
[tex]V = \pi r^2 h \: \rm unit^3\\\\V = 3.14 \times 7^2 \times 8.5 \: \rm unit^3\\\\V =1307.81[/tex]
Therefore, the volume of cylinder P is 794.03 sq. in. and the volume of cylinder Q is 1307 sq. in.
