what is pi to the 30th digit (decimla place)

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

"The probability of an event is the number of favorable outcomes divided by the total number of outcomes possible".

Here the number of favorable outcomes is 4, and the number of total outcomes is 6.

So the probability of NOT rolling a 1 or 6 is [tex]\frac{4}{6}[/tex] which is [tex]\frac{2}{3}[/tex]

Answer:

so involved triangles we know that one angle is 90° because of the right angle sign and you know that two x two interior angles add up to 180 angle so 90 degrees we will name the unknown angle x + x is equals to 127 degrees x is equals to 37 degrees so we have two angles are both of the triangles that is 90 degrees and 37 degrees 37 degrees is on the upper part of the triangle so it'll be 37° + 37° to get 74 degrees and the angle that you're looking for is a reflex angle so it'll be 360 degrees - 74 degrees so they think the answer is 286 degrees

Answer:

Given that,

x⁴y⁵ + x⁵y⁴ = 810

➝ x⁴y⁴(x+y) = 810 ---(1)

[tex] \: [/tex]

Further given that,

x⁶y³ + x³y⁶ = 945

x³y³(x³y³) = 945

[tex] \: [/tex]

We know,

[tex] { \boxed{{x}^{3} + {y}^{3} = (x + y)( {x}^{2} - xy + {y}^{2}) }}[/tex]

So, using this identity, we get,

➝ x³y³( x + y )( x² - xy + y²) = 945

---(2)

[tex] \: [/tex]

On dividing equation (1) and (2), we get,

[tex] \longrightarrow\frac{ {x}^{2} - xy + {y}^{2} }{xy} = \frac{945}{810} [/tex]

[tex] \longrightarrow \: \frac{ {x}^{2} + {y}^{2} }{xy} - 1 = \frac{7}{6} [/tex]

[tex] \longrightarrow \: \frac{ {x}^{2} + {y}^{2} }{xy} = \frac{7}{6} + 1[/tex]

[tex] \longrightarrow \: \frac{ {x}^{2} + {y}^{2} }{xy} = \frac{7 + 6}{6} [/tex]

[tex] \longrightarrow \: \frac{ {x}^{2} + {y}^{2} }{xy} = \frac{13}{6} [/tex]

[tex] \: [/tex]

➝ 6x² + 6y² = 13xy

➝ 6x² - 13xy + 6y² = 0

➝ 6x² - 4xy - 9xy + 6y² = 0

➝ 2x( 3x - 2y ) - 3y( 3x - 2y ) = 0

➝ ( 3x - 2y ) ( 2x - 3y ) = 0

[tex] \longrightarrow \:{ \bold{ x = \frac{3y}{2} \: \: \: or \: \: x = \frac{2y}{3} }}[/tex]

[tex] \: [/tex]

[tex] \: [/tex]

[tex]{ \underline {\underline {\red{Case:- 1 }}}}[/tex]

[tex]{ \bold{When \: x = \frac{3y}{2}}} [/tex]

In Substating the value of x in equation (1) we get,

[tex] \frac{81 {y}^{4} }{16} \times {y}^{4} \times ( \frac{3y}{2} + y) = 810[/tex]

[tex] \frac{ {y}^{8} }{16} \times ( \frac{5y}{2} ) = 10[/tex]

[tex] {y}^{9} = 64[/tex]

[tex] {y}^{9} = {2}^{6} [/tex]

[tex] \: [/tex]

[tex] \longrightarrow \: { \bold{y = {(2)}^{ \frac{2}{3} } }}[/tex]

[tex]{ \underline {\underline {\red{Case:- 2}}}}[/tex]

[tex]{ \bold{When \: x \: = \frac{2y}{3} \rightarrow \: \: y = \frac{3x}{2} }}[/tex]

On Substituting the value of y in equation (2), we get,

[tex] \frac{81 {x}^{4} }{16} \times {x}^{4} \times ( \frac{3x}{2} + x) = 810[/tex]

[tex] \frac{ {x}^{8} }{16} \times ( \frac{5x}{2} ) = 10[/tex]

[tex] {x}^{9} = 64[/tex]

[tex] {x}^{9} = {2}^{6} [/tex]

[tex] \: [/tex]

[tex] \longrightarrow \: { \bold{x \: = {(2)}^{ \frac{2}{3} } }}[/tex]

The 90% confidence interval for the population mean is (132.1, 143.9). Then the correct option is C.

The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.

A simple random sample of 90 is drawn from a normally distributed population, and the mean is found to be 138, with a standard deviation of 34.

The 90% confidence interval for the population mean. Then we have

[tex]\rm Margin \ of \ error = z * \dfrac{Standard \ deviation}{\sqrt{sample \ size}}\\\\\\\Margin \ of \ error = 1.645 * \dfrac{34}{\sqrt{90}}\\\\\\Margin \ of \ error = 5.9[/tex]

The interval will be given as

Mean ± Margin of error

138 ± 5.9

Then the interval will be (132.1, 143.9).

Answer:

-5x² + 2x + 3

Step-by-step explanation:

Since its a trinomial, it has three terms.

Since it has a degree 2, the highest degree is 2 and will usually be the first term.

The coefficient of the first term must have a -5.

Standard form is like  ax² + bx + c

Where a,b, and c are variables.

So,  -5x² + 2x + 3 should work

Answer:

General form of an exponential function:  [tex]y=ab^x[/tex]

where:

If [tex]b > 1[/tex]  then it is an increasing function

If [tex]0 < b < 1[/tex] then it is a decreasing function

Also [tex]b\neq 1[/tex]

Given:

[tex]\implies y=(-3)b^x[/tex]

If we want the function to be decreasing, then as [tex]a[/tex] is negative, we need [tex]b > 1[/tex] to make the overall function decreasing.  

Let [tex]b=2[/tex] :

[tex]\implies y=(-3)2^x[/tex]

If we want the function to be increasing, then as [tex]a[/tex] is negative, we need [tex]0 < b < 1[/tex] to make the overall function increasing.

Let [tex]b=\dfrac12[/tex] :

[tex]\implies y=-3\left(\dfrac12\right)^x[/tex]

However, it doesn't matter whether the function is increasing or decreasing as the range of both of the above given functions is < 0 as [tex]a[/tex] is negative and [tex]b[/tex] is positive.

an= $,500 (x5) n-1

Step-by-step explanation:

The error is the n-1 because this means a number subtracted by 1 there for it would be 1.500 subtracted by 1 but this info is not needed.

Answer:

n>4

Step-by-step explanation:

1. Let's first simplify each sides.

7 + 13n − 1 > 5(2n+2) + 8

a. 7 - 1

Distribute the 5.

b. 5 x 2n = 10n

   5 x 2 = 10

c. 10n + 10 + 8 = 10n + 18

13n + 6 > 10n + 18

2. Now, eliminate 10n on both sides, as there can't be 2 variables on the opposite sides.

13n  + 6 > 10n + 18

-10n        -10n

a. 3n + 6 > 18

3. Subtract 6 from each side.

3n + 6 > 18

     -6     -6

a. 3n > 18

Divide 3

b. n > 4

Answer

D. -18

Step-by-step explanation:

p ( x ) = 5x + 30, q ( x ) = 11x -24

( q - p ) (6 ) = 11x -24 - ( 5x + 30 )

                  = 11.6 - 24 - 5.6 - 30

                  = 66 - 24 - 30 -30

                  = 12 -30

                  = -18

4. Translation 6 unit right and 2 units down.

Step-by-step explanation:

Let' take the point and it's corresponding image.

x(-2,0) and x'(4,-2)

Now,let's find the translation

-2+? =4

0+? =-2

Now, if we solve each for ?, we get

-2+?=4, gives ? =6

0+?=-2 gives ?=-2

It means the translation is move right 6 units and down 2 units.

So, option 4 is right.

Answer:

C. If a number has a negative cube root, then the number is negative.  

Step-by-step explanation:

took the quiz

The inverse of the conditional statement is " If a number does not have a negative cube root, then the number is not negative. "

A conditional statement is a type of logical statement that expresses a relationship between two propositions or statements. It typically takes the form "if p, then q" where p and q are propositions. The statement "if p, then q" is read as "if p is true, then q is true" or "p implies q".

The truth value of a conditional statement depends on the truth values of its antecedent (p) and its consequent (q). If p is true and q is true, then the conditional statement is true. If p is true and q is false, then the conditional statement is false. If p is false, then the truth value of the conditional statement is irrelevant and it is said to be vacuously true.

Given data ,

Let the statement be represented as A

Now , the inverse of the statement is A'

where A = "If a number is negative, then it has a negative cube root."

Now , the inverse of the conditional statement is

A' = " If a number does not have a negative cube root, then the number is not negative. "

Hence , the inverse is " If a number does not have a negative cube root, then the number is not negative. "
