I got 100% :>

Answer:

99% C.I of the population mean is ( 11746, 11800 )

Step-by-step explanation:

Given the data in the question;

Sample size n = 9

mean x" = 11773  

standard deviation s = 24

for 99% confidence interval

∝ = 1 - 99% = 1 - 0.99 = 0.01

∝/2 = 0.01/2 = 0.005

degree of freedom df = n - 1 = 9 - 1 = 8

now, Critical t-value : [tex]t_{\alpha /2, df[/tex] =  [tex]t_{0.005, 8[/tex] = 3.355

Now, at 99% Confidence interval of the mean population is;

x" ± [ [tex]t_{\alpha /2, df[/tex] × s/√n ]

we substitute

11773  ± [ 3.355  × 24/√9 ]

11773   ± [ 3.355  × 8 ]

11773 ± 26.84

so

⇒ {11773 - 26.84}, {11773 + 26.84}

⇒ ( 11746, 11800 )

Therefore, 99% C.I of the population mean is ( 11746, 11800 )

Answer:

$22.00

Step-by-step explanation:

sales price x .05 = $1.90

Sales price = $1.90/.05

sales price = $38.00

total sales price less price of gloves = price of scarf

$38.00 - $16.00 = $22.00

The probability that Luca will win Wheel of Letters for this considered case is 6/13

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}}[/tex]

where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

For this case, the sample space of result of wheel of letters spin is

S = {A, B, ..., Z} , thus, n(S) = size of S = 26

Let E = event that the spinner will stop in one of the letters in  “COUNTRY PHRASE”

Then, the outcomes in favor of E are {'P', 'O', 'C', 'A', 'T', 'R', 'Y', 'N', 'H', 'S', 'U', 'E'}

Thus, n(Favorable cases for E) = 12 (counted unique ones, and not repeated), as each letter is only 1 time in the spinner.

Thus, we get:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{12}{26} =\dfrac{6}{13}[/tex]

Thus, the probability that Luca will win Wheel of Letters for this considered case is 6/13

Answer:

C. $45

Step-by-step explanation:

If 2 pounds of coffee costs $17.95, we divide this number by two to get the cost of one pound of coffee.

This value is equal to $8.975 and we multiply this number by 5 to get 5 pounds of coffee.

This is about equal to option C. $45

Answer:

4 4/9

Step-by-step explanation:

First, you have to set it up: 5/9 times 8/1

We made it 8/1 since it has to be a fraction in the multipying ocess and the one does not change the value.

Next, Multiply.

5/9x8/1=40/9 as an inproper fraction

As a proper fraction, it is written as 4 4/9

Answer:

<1 = <8

Step-by-step explanation:

Pair of alternate exterior angles are formed when two parallel lines are cut across by abl transversal line. The two angles are found on the other side of the parallel lines but located on opposite sides along the transversal line.

Thus, <1 and <8 are exterior angles of the parallel lines that are crossed by the transversal and they are on the alternate sides along the transversal.

Therefore, <1 and <8 form a pair of alternate exterior angles.

<1 = <8

Answer:

the volume of the sphere is 507.78981 cm^3

Step-by-step explanation:

The computation of the volume of the sphere is given below:

Given that

The Diameter is 9.9 cm

So, the volume of the sphere is

= 4 ÷ 3 ×π × r^3

= 4 ÷ 3 × 3.14 × 9.9 ÷ 2^3

= 4 ÷ 3 × 3.14 × 4.95^3

= 507.78981 cm^3

Here r denotes the radius

And, the radius would be comes by dividing the diameter from 2

Hence, the volume of the sphere is 507.78981 cm^3

Answer:

Answer: 16.81 min

Step-by-step explanation:

Given

Initial concentration [tex]A_o=970\ gm[/tex]

Half-time  [tex]T_{\frac{1}{2}}=6\ min[/tex]

Decay at any time t is given by

[tex]A=A_o2^{\dfrac{-t}{T_{\frac{1}{2}}}}[/tex]

put values

[tex]\Rightarrow 139=970\cdot 2^{\dfrac{-t}{6}}\\\\\Rightarrow 2^{\dfrac{t}{6}}=6.978\\[/tex]

Taking log both sides

[tex]\Rightarrow \dfrac{t}{6}\times \ln (2)=\ln (6.978)\\\\\Rightarrow t=6\times 2.802\\\Rightarrow t=16.81\ \text{min}[/tex]

Answer:

a) 3

b) 3

c) because of the permutations and combinations involved

Step-by-step explanation:

a) Determine the smallest number of cars needed

The number of cars are the same as conflict free cars

hence we can group the friends without conflict into the same car

1st car we will have : ACFI  in it

2nd car we will have : GD  in it

third care we will have : BEJH  in it

∴ number of car needed = 3

b) number of conflict free cars = 3

c) Coloring is important in the question because of the permutations and combinations involved

Answer:

[tex] x = 6 , -2[/tex]

Step-by-step explanation:

Let the required number be x .

According to the Question ,

[tex]\implies x^2 - 12 = 4x \\\\\implies x^2 -4x -12 = 0 \\\\\implies x^2 -6x + 2x -12 = 0 \\\\\implies x(x-6)+2(x-6) = 0 \\\\\implies (x-6)(x+2)=0\\\\\implies \boxed{\boxed{ x = 6 , -2}}[/tex]

Hence the number can be 6 or -2.

Answer:

The least common multiple is [tex]280a^6b^4cd[/tex]

Step-by-step explanation:

We find the least common multiple of the constant, and of each term.

Least common multiple of 40 and 28:

40 - 28|2

20 - 14|2

10 - 7|2

5 - 7|5

1 - 7|7

1 - 1

2*2*2*5*7 = 280

LCM of a^3 and a².

Exponents are 3 and 2.

LCM of 3 and 2 is 6. So

[tex]a^6[/tex]

b and b^4

LCM of 1 and 4, which are the exponents, is 4. So

[tex]b^4[/tex]

c and c

LCM of 1 and 1 is 1. So c

d

In the first term, no d means that it is [tex]d^0 = 1[/tex]

In the second, [tex]d^1 = d[/tex]

LCM of 0 and 1 is 1. So

d

Least common multiple:

Multiplication of all the LCM's. So

Answer:

40units²

Step-by-step explanation:

find the shapes you know the formula of. There's two shapes a rectangle and a trapezoid.

do the formula for rectangle

A = bh

A = 8×2

A = 16

Now the formula for Trapezoid

A = 1/2h(b+b)

A = 1/2×4(4+8)

A = 1/2×4(12)

A = 1/2(48)

A = 24

16+24 = 40
