thrown from a height of 25 feet and goes up at a rate of 3 feet per second. After how many seconds
would the two reach the same height?

We could say 18 + 6 = 2(9+3) as one example

The probability that the lot of the bulbs will fail inspection of the quality control inspector is 0.9856

Given data

p = 20%

sample drawn = 19 bulbs

20% of the bulbs in the lot are defective

n = 19

p = 20% = 0.20

if 20% of the bulbs are defective to find the non defective bulbs we solve as follows

q = 1 - p

= 1 - 0.20

= 0.80

Using binomial theorem,

[tex]P ( X = x) = (^n C _{x} ) * p x * (1 - p)n - x[/tex]

[tex]= 1 - P ( x < 1 )[/tex]

[tex]= 1 - P ( X = 0)[/tex]

[tex]= 1 - ( ^{19} C _{0} ) * 0.20^0 * (0.80)^{19}[/tex]

[tex]= 1 - 1 * 1 * 0.01441[/tex]

[tex]= 1 - 0.01441[/tex]

= 0.98559

= 0.9856 (to four decimal place)

Answer: He could put 8 blocks in 8 stacks

Step-by-step explanation:

Ken could put the blocks in stacks of 1, 2, 4, 8, 16, 32, or 64.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To find out how many blocks Ken could put in each stack, we need to divide the total number of blocks by the number of stacks.

So we have:

Number of blocks = 64

Number of stacks = x

To find out how many blocks can be put in each stack, we can set up the following equation:

64 / x = y

where y is the number of blocks in each stack.

Solving for y, we get:

y = 64 / x

So if Ken wants to put all 64 blocks into the same number of stacks, he can put:

64 blocks in 1 stack

32 blocks in 2 stacks

16 blocks in 4 stacks

8 blocks in 8 stacks

4 blocks in 16 stacks

2 blocks in 32 stacks

1 block in 64 stacks

Therefore,

Ken could put the blocks in stacks of 1, 2, 4, 8, 16, 32, or 64.

If f(x) = x² ₋ 4x ₋ 6 then we get the following answers for f(0),f(3) and f(-2) respectively. And the expression f(1/2) = f(7/2) and f(2₋h) = f(2₊h) is therefore proved.

f(0) = -6

f(3) = -9

f(-2) = 6

Given the function is f(x) = x² ₋ 4x ₋ 6

we need to find for f(0):

f(0) = 0² ₋ 4(0) ₋ 6

f(0) = ₋6

f(3) = 3² ₋ 4(3) ₋ 6

f(3) = 9 ₋ 12 ₋ 6

f(3) = ₋9

f(₋2) = (₋2)² ₋ 4(₋2) ₋ 6

f(₋2) = 4 ₊ 8 ₋ 6

f(₋2) = 6

we need to prove f(1/2)f(7/2)

now, f(1/2) = (1/2)² ₋ 4(1/2) ₋ 6

f(1/2) = 1/4 ₋ 2 ₋ 6

f(1/2) = 1 ₋ 8 ₋ 24 / 4

f(1/2) = ₋31/4

f(7/2) = (7/2)² ₋ 4(7/2) ₋ 6

f(7/2) = 49/4 ₋ 14 ₋ 6

f(7/2) = 49 ₋ 56 ₋ 24 / 4

f(7/2) = ₋31/4

therefore, f(1/2) = f(7/2)

f(2₋h) = (2₋h)² ₋ 4(2₋h) ₋ 6

f(2₋h) = (4 ₊ h² ₋ 4h) ₋ 8 ₊ 4h ₋ 6

f(2₋h) = h² ₊ 4 ₋ 4h ₋ 8 ₊ 4h ₋ 6

f(2₋h) = h² ₋ 10

f(2₊h) = (2₊h)² ₋ 4(2₊h) ₋ 6

f(2₊h) = 4 ₊ h² ₊ 4h ₋ 8 ₋ 4h ₋ 6

f(2₊h) = h² ₋ 10

therefore, f(2₋h) = f(2₊h)

Hence proved.

It is recommended that the expressions

d = 400 - 256 and

d = 256 - 400 be considered when attempting to determine how much farther Adam can see to the horizon.

Since, the eye-level height of Pam is 256 feet above sea level, whereas the eye-level height of Adam is 400 feet above sea level.

Therefore, the formula that indicates how much farther Adam can see to the horizon should be taken to be

d = 400 - 256 and

The partial products of 3706 × 4 is ( 3000 × 4 ) + ( 706 × 4 ).

Calculating the product of two or more numbers is the procedure known as multiplication in mathematics. When two integers are multiplied together in mathematics, the result is a product or an expression that describes the factors to be multiplied.

The decimal numeral system is widely used to express both integer and non-integer numbers. The way of representing numbers in the decimal system is known as decimal notation.

The given product is 3706 × 4 and can be written as:-

3706 × 4 = [ 3000 + 706 ] × 4

3706 × 4 = ( 3000 × 4 ) + ( 706 × 4 )

Therefore, the partial products of the given expression is ( 3000 x 4 ) + ( 706 x 4 ).

The two angles shown are corresponding angles. They are corresponding because each is in the same position left side) in its group of four angles.

Corresponding angles are equal

Therefore,15x + 9 = 21x - 27

Subtract 9 from both sides:
15x = 21x - 27 - 9

15x = 21x  - 36

Subtract 21x from both sides

15x - 21x = - 36

-6x =  36

Divide by -6 both sides

Simple interest , 4368 is  the amount of money Marty would have at the end of the second year.

What does the term "simple interest" mean?

P = $4000 R = 4% T = 1

then substitute the value into the formula = [tex]\frac{P * R * T }{100}[/tex]

                = [tex]\frac{4000 * 4 * 1}{100}[/tex]  = 160

So, the total amount is ( 4000 + 160) = 4160

Second year

P = 4160 , R = 5%  T = 1

then substitute the value into the formula = [tex]\frac{P * R * T }{100}[/tex]

                      =  [tex]\frac{4160 * 5 * 1}{100}[/tex]  = 208

So, the total amount is ( 4160 + 208 ) =   4368

2.50t + 4.00b = 175.50        (eq-2)

We take equation-1,

We can write,

              t= 60-b            (eq-3)

Substitute equation-3 into equation-2,

We can write,

          2.50t + 4.00b = 175.50

          2.50(60-b) + 4.00b = 175.50

 Multiply the values,

         2.5(60)-2.5b+4b = 175.5

         150-2.5b+4b = 175.50

Subtract the values,

           1.5b = 175.5-150

            1.5b = 25.5

             b = 25.5/1.5

Divide the values,

Replace the value 'b' in equation-3,
