Answer:

68.268%.

Step-by-step explanation:

Let \mu be the mean pregnancy length.

The given standard deviation, [tex]\sigma=7[/tex] days

The z-score:

z=\frac{x-\mu}{\sigma}

where x is any pregnancy length.

The range of x within 7 days of the mean pregnancy length is

[tex]\mu-7<x<\mu+7.[/tex]

z-score for this range is:

[tex]\frac{\mu-7-\mu}{\sigma}<z<\frac{\mu+7-\mu}{\sigma}[/tex]

[tex]\Rightarrow -1<z<1[/tex]

So, the area on the normally distributed curve for the above range of z-score will give the expected percentage of birds to occur within 7 days of the mean pregnancy length.

Now, from the z-score table:

The area from [tex]z = -\infty[/tex] to z=1 is 0.84134

and the area from [tex]z = -\infty[/tex] to z=-1 is 0.15866.

So, the area for -1<z<1

=0.84134 - 0.15866

=0.68268

Hence, the percentage of births would be expected to occur within 7 days of the mean pregnancy length=68.268%.

Answer:

8.50 divided by 1.25 then when u get the answer subtract 40

Answer:

25

Step-by-step explanation:

so instantly 40-8.50=31.5

The question is very vague because it doesn't state the number of rides he wants to go on in minimum.

if you do 1.25x25=31.25

According to that, he will leave with a change of 0.25 and obv u cannot go on half a ride...

So in about 2 mins i guess it is 25???

Answer:

x = -18, y = 14

Step-by-step explanation:

4x + 6y = 12

x + 2y = 10

Divide both sides of the first equation by 2. Write the second equation below it.

2x + 3y = 6

x + 2y = 10

Rewrite the first equation. Multiply both sides of the second equation by -2 and write below it. Then add the equations eliminating x.

      2x + 3y = 6

(+)  -2x - 4y = -20

-------------------------

             -y = -14

y = 14

Substitute 14 for y in the second equation and solve for x.

x + 2y = 10

x + 2(14) = 10

x + 28 = 10

x = -18

Solution: x = -18, y = 14

The answer is C   100

Step-by-step explanation:

Answer:

Step 1: 4 x − 3 − 2 x − 10

Step 2: 2 x − 13

Step-by-step explanation:

Given the expression;

(4 x − 3) − 2 (x + 5)

The following steps/ procedure are to be taken when simplifying the expression.

open the parenthesis

(4 x − 3) − 2 (x + 5)

= 4x-3 -2(x)-2(5)

= 4x-3-2x-10

collect the like terms

= 4x-2x-3-10

simplify the resulting expression

= 2x-13

Hence the procedure that correctly simplifies the expression are:

Step 1: 4 x − 3 − 2 x − 10

Step 2: 2 x − 13

Answer:

5 adults went on the trip.

Step-by-step explanation:

There are 14 children ($75 each) and the total was $1475. We need to find out how many adults were there ($85 each)

c is for children and a is for adults

equation:  $75c+ $85a = $1475

$75(14)+ $85a= $1475

$1050 + $85a = $1475

-1050                   -1050

$85a = $425

85a/85 = 425/85

a = 5

5 adults went on the trip. Hope this helps! :)

There were 5 adults that went on the trip.

Unitary method is finding the value for a single unit.

According to the given question During spring break, a class of 14 children went to Walt Disney World in Florida the price for each child’s ticket was 75 dollars.

So, Cost of tickets of 14 children is

= (14 × 75) dollars.

= 1050 dollars.

Total amount spent on tickets for children and adults is 1475 dollars.

∴ Total amount spent for tickets for the adults is

= ( 1475 - 1050 ) dollars.

= 425 dollars.

Given price of one ticket for adult is 85 dollars, So for 425 dollars the no. of tickets will be

= 425/85 dollars.

= 5 tickets which states there were 5 adults.

Answer:

The dimensions that result in the maximum area are therefore;

Width = 3.5

Height = 3.5

Step-by-step explanation:

The given parameters are;

The area of the rectangle, y = x × h

Where;

x = The width of the rectangle

h = The height of the rectangle

By examination, we have;

x + h = 7

Therefore, x = 7 - h

Which gives;

y = x × (x - 7) = x² - 7·x

y = x² - 7·x

At x = 0, y = 0

At x = 7, y = 0

However, at x = 1, y = -6

Therefore, the function should be, y = -(x² - 7·x)

The maximum occurs where dy/dx = 0, which gives;

dy/dx = d-(x² - 7·x)/dx = 0

dy/dx = 2·x - 7 = 0

2·x - 7 = 0

x = 7/2 = 3.5

On second derivative, we have;

d²y/dx² = 2, which gives a local minimum

x = 3.5 at maximum height

Which give, the maximum height, [tex]y_{max}[/tex] = -(x² - 7·x) at x = 3.5

∴ [tex]y_{max}[/tex] = -(3.5² - 7×3.5) = 12.25

The maximum height = 12.25

The dimensions that result in the maximum area are therefore;

Width, x = 3.5

Height, h = 7 - x = 7 - 3.5 = 3.5

Height, h = 3.5.

Answer:

x = 2

Step-by-step explanation:

-4/5(-8x + 6) = 1 + 7 (distribute first)

6.4x -4.8 = 8 (add 4.8 on both sides)

6.4x = 12.8 (divide by 6.4)

x = 2

-4/5(-8(2) + 6) = 1 + 7

-4/5(-16 + 6) = 8

-4/5(-10) = 8

About 48 members would be expected to say that dues be raised

Step-by-step explanation:

Here, we shall be using a case of a representative sampling to determine the actual.

Out of the 100 selected members, 6 said the dues should be raised;

This represents a percentage of 6/100 = 6%

So out of the 800, the expected number of members that would ask for a dues raising will be;

6/100 * 800 = 48

Answer:

-313

Step-by-step explanation:

a1=2; d=-5

a64=2-5(64-1)=-313

The 64th term of the arithmetic sequence 2, -3, -8 ... will be -313.

What is Arithmetic sequence?

An arithmetic sequence is the sequence of numbers where each consecutive numbers have same difference.

Given that;

The arithmetic sequence;

⇒ 2 , -3 , -8 ...

Now,

The general equation for nth term of the arithmetic sequence is,

[tex]T_{n} = a + (n - 1) d[/tex]

Where, The term 'a' represent the first term.

And, 'd' represent the difference between each consecutive numbers.

Here, In the arithmetic sequence 2 , -3, -8;

The first term = 2

The difference = -3 - (2) = - 5

So, To find the 64th term of the arithmetic sequence, we can substitute

n = 64 and a = 2 and d = -5 in above formula as;

[tex]T_{n} = a + (n - 1) d[/tex]

[tex]T_{64} = 2 + (64 - 1) (-5)[/tex]

[tex]T_{64} = 2 + (63 * -5)[/tex]

[tex]T_{64} = 2 - 315[/tex]

[tex]T_{64} = -313[/tex]

Thus, The 64th term of the arithmetic sequence 2, -3, -8 ... will be -313.
