Answer:

3

Step-by-step explanation:

first, let's find out how much Lyle wrote on Friday.

(2/3)(9)=6

Lyle wrote 6 pages on Friday.

9-6=3

this makes sense, because since he wrote 2/3 of the report on Friday, there will be 1/3 of the report to do on Saturday. (1/3)(9)=3

LYLE WROTE 3 PAGES ON SATURDAY

Answer:

Ling's principal can hire new teachers in 54 different ways.

Step-by-step explanation:

Since Ling's elementary school principal wants to hire some new teachers, and 6 teachers applied for one 1st grade teaching job, and 3 teachers applied for one 2nd grade teaching job, and there is also a job opening for a 3rd grade teacher, and 3 teachers applied for the job, to determine how many different ways can Ling's principal hire new teachers the following calculation has to be done:

6 x 3 x 3 = X

18 x 3 = X

54 = X

Therefore, Ling's principal can hire new teachers in 54 different ways.

Answer:

D. 5 1/8

Step-by-step explanation:

First, convert the mixed number into an improper fraction

8-2 7/8 = 8- 23/8

Calculate the difference

8-23/8 = 41/8

Simplify the fraction

41/8 = 5 1/8

Answer:

its 28

Step-by-step explanation:

C is the longest side which is 35 ye and b is 21 yd. Then you would subtract 21^2 from 35^2 and you would get 784. Then find the square root of 784 and you would get 28 as the answer! Good luck and have a great day or night!

Answer:

28 yards

Step-by-step explanation:

We can use pythagorean theorem to solve this problem; pythagorean theorem is denoted by the formula a^2 + b^2 = c^2. We already have b, as 21 yd and c, as the hypotenuse is 35 yd. We can plug these values into the formula:

a^2 + 21^2 = 35^2

a^2 + 441 = 1225

a^2 = 784

a = 28 yards

Answer:

A- impossible

B- unlikely

C- even chance

D- likely

E- certain

Step-by-step explanation:

A to E goes from 0 to 1 so I assume 0 means zero possibility (impossible) then to continue unlikely. now even chance at C (in the middle which makes sense) then likely and then 1 is certain  

Answer:i think A is impossible, B is unlikely, C is even chance, D is likely, and E is certain

Answer:

D. III, II, then I

Step-by-step explanation:

To find the space between the cylinder and the cone, the first thing to do is: find the volume of the cylinder => next is to find the volume of the cone => then look for the difference in volume between the cylinder and the cone which will give us the space between the cylinder and the cone.

The correct order would be:

III, II, then I

Answer: it’s 959cm squared.

Step-by-step explanation:

The total surface area of the new box will be C) 959 square centimeters.

A rectangular prism is a three-dimensional shape that has two at the top and bottom and four are lateral faces.

The surface area of this rectangular prism = 2( lb + bh + hl)

We are given that height of the box is 4 cm.

Also that height of the original box will be increased by 3.5 centimeters so a new instruction manual and an extra battery can be included.

The surface area of this rectangular prism = 2( lb + bh + hl)

= 2(18 x 13.5 + 13.5x 7.5 +  18 x 7.5)

= 958.5

= 959 cm sq.

Therefore, the correct option is C.

Answer: A

Step-by-step explanation:

Percent means 'per 100'

So, 0.55% means 0.55 per 100 or simply 0.55/100

If you divide 0.55 by 100, you'll get 0.0055

Answer:

3/10

Step-by-step explanation:

From the question :

Let amount rytis get = x

Hence, amount Linda gets = 3x

Hence, amount Adam gets = 2 times what Linda gets = 2(3x) = 6x

Hence, total amount shared :

x + 3x + 6x = 10x

Amount Linda got = 3x

Therefore, fraction Linda gets = Amount gotten by Linda / total amount = 3x / 10x = 3/10

Hence, fraction gotten by Linda = 3/10

The fraction of the amount of money does Linda gets is 3/10 and this can be determined by using the arithmetic operations.

Given :

The following steps can be used in order to determine the fraction of the amount of money does Linda get:

Step 1 - Let the total amount of money Rytis get be 'x'.

Step 2 - So according to the given data, the total money Linda has is 3x.

Step 3 - According to the given data, the total money Adam has is 2(3x).

Step 4 - So, the total amount of money shared is:

x + 3x + 6x = 10x

Step 5 - So, the fraction of the amount of money does Linda get is:

[tex]\rm =\dfrac{3x}{10x}[/tex]

[tex]= \dfrac{3}{10}[/tex]

Answer:

Step-by-step explanation:

Assuming you're solving for p:

[tex]m=2^{-1} *2^p(2^p-1)[/tex]

Let [tex]y=2^p[/tex]

Now we can re-write the equation with [tex]y[/tex] instead of [tex]2^p[/tex].

[tex]m=\frac{1}{2} y(y-1)[/tex]

[tex]2m=y^2-y[/tex]

[tex]y^2-y-2m=0[/tex]

Use the quadratic formula to get:

[tex]y = \frac{1+\sqrt{1+8m} }{2}[/tex]

or

[tex]y = \frac{1-\sqrt{1+8m} }{2}[/tex]

Therefore, using natural log and log rules:

[tex]2^p = \frac{1+\sqrt{1+8m} }{2}[/tex], [tex]ln(2^p)= ln(\frac{1+\sqrt{1+8m} }{2})[/tex],[tex]pln(2) = ln(\frac{1+\sqrt{1+8m} }{2})[/tex], [tex]p = \frac{ln(\frac{1+\sqrt{1+8m} }{2})}{ln(2)}[/tex]

or

[tex]2^p = \frac{1-\sqrt{1+8m} }{2}[/tex], [tex]ln(2^p)= ln(\frac{1-\sqrt{1+8m} }{2})[/tex], [tex]pln(2) = ln(\frac{1-\sqrt{1+8m} }{2})[/tex], [tex]p = \frac{ln(\frac{1-\sqrt{1+8m} }{2})}{ln(2)}[/tex]

Answer:

H0 : μ = 2

H1 : μ > 2

We fail to reject the null and conclude that no significant evidence exists to support that mean tree-planting time differs from two hours.

Step-by-step explanation:

Given :

X = 23.71,17.79,29.87,18.78,28.76

Sample mean, xbar = Σx / n = 22/10 = 2.2

Standard deviation, s = 0.516 (calculator)

H0 : μ = 2

H1 : μ > 2

Test statistic :

(xbar - μ) ÷ (s/sqrt(n))

n = 10

Test statistic :

(2.2 - 2) ÷ (0.516/sqrt(10))

0.2 / 0.1631735

Test statistic = 1.23

Using the Pvalue from Tscore calculator, df = n - 1 = 10 - 1 = 9

Pvalue(1.23, 9) = 0.1249

Since, Pvalue > α ; We fail to reject the null and conclude that no significant evidence exists to support that mean tree-planting time differs from two hours.
