Answer:

The number of ways = 151200

Step-by-step explanation:

Below is the calculation of the number of ways:

Total number of people = 10

Total number of posts = 6

The number of ways = 10P6

The number of ways = \(\frac{10!}{10! - 6!}\)

The number of ways = 10 x 9 x 8 x 7 x 6 x 5

The number of ways = 151200

Weight is in Olivia's backpack is 5/6 pound.

As in the given problem olivia's  history book weights 1/2 of a pound and

her lunch weighs 2/3 of a pound.

As both the units are same,

Thus total weight must be summation of both history book and her lunch  box.

total weight is =1/2 +2/3 pound

= (3+2)/6

that is equal to 5/6 pound.

Answer:

A = 35 degrees

Step-by-step explanation:

70 + 75 + A = 180

145 + A = 180

A = 35

The 95 percent confidence interval is (0.20, 0.32).

a. We can construct a 95% confidence interval to estimate the percentage of yellow peas as follows:

Let p = proportion of yellow peas = 155/595 = 0.26

Sample size = n = 595

Standard error = SE = √(p × (1-p) / n) = √(0.26 × (1-0.26) / 595) = 0.03

95% confidence interval = p ± 1.96 × SE

= 0.26 ± 1.96 × 0.03

= 0.26 ± 0.06

So, the 95% confidence interval is (0.20, 0.32).

b. Yes, the results of the experiment appear to contradict the expectation that 25% of the offspring peas would be yellow, as the 95% confidence interval does not include the expected value of 0.25.

Therefore, the 95 percent confidence interval is (0.20, 0.32).

Answer:

672 sq cm

Step-by-step explanation:

Each triangular base is 1/2 (12 * 8) or 48, making them = 96.

One of the sides is 12 x 18 = 216

The other 2 sides are 10 x 18 = 180 x 2 = 360

Add them all together to get 672 sq cm

The number of peanuts sold is 140 and the number o cotton candies sold is 40.

$4c + $2.5p = $460 equation 1

c + p = 160 equation 2

Where:

c = cotton candy

p = peanuts

Multiply equation 2 by 4

4c + 4p = 640 equation 3

Subtract equation 1 from equation 3

$1.50p = 180

p = 120

120 + c = 160

c = 160 - 120

c=  40

Answer:

20 square inches

Step-by-step explanation:

No. of bags Huma has : 4

No. of tiles in one bag: 6

Total no . of tiles in 4 bag = 4 * No. of tiles in one bag

                                             = 4*6 = 24

No of tiles left with huma = 4

Let x be the no of tiles used to cover rectangle

Hence,

sum of no. of tiles left with huma and no of tiles used to cover rectangle should be equal to Total no . of tiles in 4 bag

mathematically

no. of tiles left with huma(4) + no of tiles used to cover rectangle (x) =  Total no . of tiles in 4 bag (24)

4 + x = 24

subtracting 4 from both sides

4 + x -4 = 24 - 4

=> x = 20

Thus, 20 square inches tiles are used to cover the rectangle.

This means that area of rectangle is 20 square inches .

The number of days took to get the video of Felipe 1024 views is 4.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

The relationship between the elapsed time in days, d, since the video was uploaded and the total number of views, v, that the video received is modeled by the equation,

v = 4^(1.25d)

We have to find d when v = 1024

1024 = 4^(1.25d)

We have the rule for exponents aᵇⁿ = (aᵇ)ⁿ

1024 = \((4^{1.25} )^d\)

1024 = (5.6569)^d

Taking logarithms on both sides,

㏒ (1024) = ㏒ [(5.6569)^d]

We have the exponent rule for logarithm, ㏒ (aᵇ) = b ㏒ (a)

㏒ (1024) = d ㏒ (5.6569)

d = ㏒ (1024) / ㏒ (5.6569)

d = 4

Hence it took 4 days to for Felipe's video to get 1024 views.

The statement translated to an algebra equation will give the value of the unknown number w = 11/5

Algebra is the branch of mathematics that helps to represent problems or values in the form of mathematical expressions using letters to represent unknown values.

Let us represent the unknown number with the letter w so that the statement can be written as the equation:

5w - 8 = 3

add 8 to both sides

5w - 8 + 8 = 3 + 8

5w = 11

divide through by 5

5w/5 = 11/5

w = 11/5

Answer:

x = 2

Step-By-Step Explanation:

It is really easy to see that the angle on the left side is almost equal to 90° (Right Angle) but is a bit less.

35 × 1 + 3 = 38 F It is too less than 90°

35 × 2 + 3 = 73 T It is closer and less than 90°

35 × 3 + 3 = 108 F It is close but more than 90°

35 × 4 + 3 = 143 F It is too much more than 90°

So,

x = 2

Double Checking

(180° - (35° × 2 + 3)) + (2 + 39°) + (3 + 30°)

= (180° - 73°) + 41° + 32°

= 107° + 41° + 32°

= 180°

Answer:

First find the sales tax: $160 \times 0.0785 = $12.56.

Then add the sales tax to the price of the purchase to find the total cost: $160 + $12.56 = $172.56.

Next find the daily interest rate: $0.042\% = 0.00042$.

Then multiply the daily interest rate by the total cost to find the interest per day: $0.00042 \times $172.56 = $0.0725752$.

Finally, multiply the interest per day by 30 days to find the total interest and add it to the total cost to find the final answer: $0.0725752 \times 30 = $2.177256 + $172.56 = $174.737256 \approx $174.74.

Number of seats in each row is 51 given that a rectangular auditorium seats 2244 people and number of seats in each row exceeds the number of rows by 7. This can be obtained by assuming the value of number of seats in each row, forming quadratic equation and using quadratic formula to find root.

Here in the question it is given that,

We have to find the number of seats in each row.

Let us assume that the number of seats in each row be x.

From the given statement, number of seats in each row exceeds the number of rows by 7, we can write that,

Number of seats in one row = Number of rows + 7

x = Number of rows + 7

⇒ Number of rows = x - 7

Total number of seats in the auditorium can be written as,

⇒ (Number of seats in one row)(Number of rows) = Total number of seats

(x)(x - 7) = 2244

x² - 7x = 2244

⇒ x² - 7x - 2244 = 0

By using quadratic formula we can find the root,

x = (-b ± √b² - 4ac)/2a

here in the question, a = 1, b = -7, c = -2244

√b² - 4ac = √(-7)² - 4(1)(-2244)

√b² - 4ac = √49 + 8976

√b² - 4ac = √9025

√b² - 4ac = 95

x = (-b ± √b² - 4ac)/2a

x = (7 ± 95)/2

x = 102/2 or x = -88/2

⇒ x  = 51 or x = -44

Hence number of seats in each row is 51 given that a rectangular auditorium seats 2244 people and number of seats in each row exceeds the number of rows by 7.

EXPLANATION

We first need to represent the coordinates in a graphing calculator:

We can get the distance from A to B by subtracting the x-axis coordinates:

distance AB= (4-(-4),5-5)

Subtracting numbers:

distance AB = (4-(-4),5-5)

distance AB = ( 8 ,0)

The first part is equivalent to 8 units.

Now, we can get the distance from B to C by applying the distance formula:

Where (x_1,y_1) = (4,5) and (x_2,y_2) = (-3,-4)

Plugging in the values into the equation:

Subtracting numbers:

Computing the powers:

Adding numbers:

Simplifying:

The distance from B to C IS 11.40

Applying the same reasoning for the distance from C TO A give us distance CA=9.06

Adding all the distances:

AB + BC + CA = 8 + 11.4 + 9.06

Adding numbers:

= 28.46
