A person must have a score of 126.26 to qualify Mensa.

it is given that,

Mean [tex](\mu) = 100,[/tex]

Standard deviation [tex](\sigma) = 15[/tex].

A person must score in the upper 4% of the population,

100% - 4% = 96% = 0.96

P(X < Xo) = 96% = 0.96

P(X < 1.7507) = 0.96          ....................................using the Normal distribution table,

Or, when the Invnorm function is used, Invnorm(0.96) = 1.7507

Therefore, The required value of X is,

[tex]Z = \frac{(X - \mu )}{ \sigma }[/tex]

1.7507 = (X - 100) / 15

X - 100 = 26.26

X = 100 + 26.26

X = 126.26

thus, the score a person must have to qualify Mensa is 126.26.

The events “blonde hair” and “brown eyes” are not independent.

What are independent events?

The term "independent events" refers to those whose occurrence is not reliant on another event.

When two events A and B are independent then the intersection of the two events is equal to zero. i.e. They do not have any element in common.

But from the given table we can see that the intersection of the events of  "blonde hair" and "brown eyes" exists.

Therefore, the events "blonde hair" and "brown eyes" are not independent.

Answer:

For x² + kx + 16/9 to be a perfect square, k should be equal to 8/3

Step-by-step explanation:

If x² + kx + 16/9 is a perfect square then it must satisfy the formula of (a + b)² i.e. equal to a² + 2ab + b².

So, first we will form a equal that looks similar to the formula:

[tex] \rm \implies {x}^{2} + kx + \dfrac{4 \times 4}{3 \times 3} \\ \\ \rm \implies {x}^{2} + kx + { \bigg( \dfrac{4}{3} } \bigg)^{2} [/tex]

Sherry needs to invest 2000$ in mutual fund and 13200$ in bond to earn 548$ at the end of the year.

A percentage is just one of the many ways that a number, ratio, or fraction can be expressed. It is a number or ratio expressed as a fraction of 100.

Given:

Sherry has 15200$ to invest in mutual funds and in bonds.

Sherry has selected a mutual fund that earns 1% a year and a bond that earns 4% a year.

Here we need to find how much does she need to invest in each type of account if she wants to earn 548 at the end of the first year.

Here we have total amount = 15200$

So, let us consider x be the amount invested in mutual funds, then the amount invested in bonds will be 15200 - x.

It can be written in the following matrix

[x     15200-x ]

We know that the total amount earned at the end of the year is 548.

So, it can be written as

amount invested x percentage = final amount

[tex]\left[\begin{array}{cc}x&15200-x\\\\\end{array}\right][/tex]*[tex]\left[\begin{array}{ccc}1/100\\4/100\\\end{array}\right][/tex] = 548

We can simply it as

[x*1/100 + (15200 - x)*4/100] = 548

⇒ x/100 + 60800/100 - 4x/100 = 548

⇒ x + 60800 - 4x = 54800

⇒ -3x = 54800 - 60800

⇒ -3x = -6000

⇒ x = 2000

⇒ 15200 - 2000 = 13200

Therefore, Sherry invests 2000$ in mutual funds and 13200$ in bond to earn 548 at the end of the year.

The volume of prism with 1 layer=16 inch³; The volume of prism with 3 layer=48 inch³;The volume of prism with 5 layer=80 inch³;The volume of prism with 7 layer=112 inch³.

The total amount of space an object occupies in three dimensions is indicated by its volume. The term "capacity" describes something's ability to hold, absorb, or receive by an object .

Here,

Since each layer is of 1 inch.

So the volume of first prism,

=4*4*1

=16 inch³

When there is 3 layer, so the height is 3 inch,

=4*4*3

=48 inch³

When there is 5 layer, so the height is 5 inch,

=4*4*5

=80 inch³

When there is 7 layer, so the height is 7 inch,

=4*4*7

=112 inch³

The volume of a prism with one layer is equal to 16 inch³; with three layers, it is 48 inch³; with five layers, it is 80 inch³; and with seven layers, it is 112 inch³.

Answer:

Step-by-step explanation:
Here is an example:
Use this step by step explanation in your equation to help you find the answer.
For polynomial 2x2 - 3x5 + 5x6.

We observe that the above polynomial has three terms. Here the first term is 2x2, the second term is -3x5 and the third term is 5x6.

Now we will determine the exponent of each term.

(i) the exponent of the first term 2x2 = 2

(ii) the exponent of the second term 3x5 = 5

(iii) the exponent of the third term 5x6 = 6

Since, the greatest exponent is 6, the degree of 2x2 - 3x5 + 5x6 is also 6.

Therefore, the degree of the polynomial 2x2 - 3x5 + 5x6 = 6.

The speed of 213.25 mph  is the red car actually traveling along the road.

What is speed?

The definition of speed is the pace of movement of an object (covering a particular distance). It defines only the magnitude and not the direction, making it a scalar quantity.

The meter per second (m/s) unit of speed is taken from the SI.

let distance between the police and red cars = h

distance from the red car to a point horizontal to the police car = a

distance from from the road to the police car = b

=>[tex]h^2=a^2+b^2[/tex]

take the derivative with respect to time

=>hh' = aa' + bb' b'=0

=>174.64(75) = 90a'

=>a' = 174.64(75)/90 = 145.4ft/sec

=>145.4ft/sec = 145.4(5280)/60^2 = about 213.25 mph

Here ,1 mile = 5280 feet

=>1 hour = 60 minutes x 60 seconds = 3600 seconds

=>1 mile per hour = 5280 feet per 3600 seconds

=>1 foot per second = 5280/3600 mph = 1.4666...mph

=>145.4x 1.4666... = 213.25 mph

Hence 213.25 mph speed  is the red car actually traveling along the road.

The length and width of a rectangle that maximises the enclosed area are 162.5 yards. The maximum area is 26,406.25 square yards.

In the given question we have to find the maximum area of the rectangular area.

A farmer with 650 meters of fencing wants to enclose a rectangle plot that border on a river.

As we know that the perimeter of rectangle

P= 2(l+b)

Let length of the rectangle is x yards and width is y yards.

So the equation should be

2(x+y) = 650

Divide by 2 on both side we get

x+y = 325................(1)

From the area of rectangle is

A = xy

From the equation the value of y is 325-x.

Now putting the value of y

A = x(325-x)

A = 325x-x^2

On differentiating

dA/dx = 325-2x

Putting dA/dx=0

325-2x=0

Subtract 325 on both side we get

-2x= -325

Divide by -2 on both side we get

x = 162.5 yards

Now putting the value of x in the y=325-x

y=325-162.5

y=162.5 yards

So the maximum area is

A= 162.5*162.5

A= 26,406.25 square yards

Hence, the length and width of a rectangle that maximises the enclosed area are 162.5 yards. 26,406.25 square yards is the maximum area.

Step-by-step explanation:

Without decimal, 4 canisters need to buy for making 5 meatloafs for party or if answer in decimal values needed then it is 3.333 canisters.

From the provided data, we have

number of meatloafs = 5

Here we have need the cup measurements the number of meatloafs made per recipe and the net weight of canister.

net weight of the contents of 1 canister = 15 ounces

1 cup = 8 ounces

1.25 cups = 10 ounces

10 ounces of breadcrumbs makes 1 meatoafs.

but we made 5 meatloafs so, for 5 meatloaf needed breadcrumbs = 5×10

= 50

If we consider 4 canisters then

15ounces × 4 canisters = 60 ounces which are 10 more than the needed ( > 50 ounces.

and if we are consider 3 canisters then

15 ounces × 3 canisters = 45 ounces which is not enough.

So, we need 4 canisters of breadcrumbs and we will have 2/3 of a canister left over.

approximately 3.333 is a value of needed canisters in decimals values. If decimal values are not need ,i.e, whole are canisters are not partial then 4 canisters is right .
