The probability of having blood type a is 0.4, and the chance that nobody has blood type A is 0.1296, or about 12.96%.

The probability of having blood type a is 0.4.

Let x be the number of them with blood type a.

Choose 4 people at random.

The number of people with blood type a can be 0, 1, 2, 3, or 4. These are the possible values of X. If there are 4 people with blood type a, then nobody does have blood type a. Otherwise if X is less than 4, then at least one person does not have blood type a. It means we want to find P(X = 0).

X is a binomial random variable with parameters n = 4 and p = 0.4.

The probability mass function of X is given by:

P(X = x) = (n C x) * (p)^x * (1-p)^(n-x)

Now, for P(X = 0), let x = 0, n = 4, and p = 0.4.

P(X = 0) = (n C x) * (p)^x * (1-p)^(n-x)

⇒ (4 C 0) * (0.4)^0 * (0.6)^(4-0)

⇒ 0.1296

Therefore, the chance that nobody has blood type a is 0.1296.

1 doll shirt can be finished with 5 buttons if A machine makes 5 buttons at a time and Each doll shirt gets 5 buttons.

The given data is as follows:

Number of buttons the machine makes = 5 Buttons

Number of buttons that each doll shirt has = 5 Buttons

How many doll shirts can be finished with 5 buttons?

Here, we simply have to divide the number of buttons made each time by the number of buttons required for a doll shirt.

Mathematically,

doll shirts can be finished with 5 buttons =

( Number of buttons the machine makes / Number of buttons that each doll shirt has)

doll shirts can be finished with 5 buttons = 5/5 = 1

Therefore we can conclude that 1 doll shirt can be finished with 5 buttons.

The crucial value (z) relies on the desired level of confidence and is predicated on a normal distribution when creating a confidence interval for a proportion (p) with a confidence level of 93%.

A 93% confidence level in this instance translates to an alpha level of 0.07 (1 - 0.93 = 0.07) that is split evenly between the two tails. In the usual normal distribution table, we search for the value that falls within the range of 0.07 to find the proper z-value. A 93% confidence level corresponds to a z-value of roughly 1.81. The confidence interval for the proportion p may be calculated using this number and provides a range where the genuine proportion is like to fall.

Answer:

Step-by-step explanation:

The statement to prove is that PQ is the shortest segment from point P to plane M when PQ is perpendicular to plane M.

To prove that PQ is the shortest segment from point P to plane M, we can use the concept of perpendicularity. When PQ is perpendicular to plane M, it forms a right angle with the plane.

In Euclidean geometry, it is known that the shortest distance between a point and a plane is along the line perpendicular to the plane passing through the point.

Therefore, since PQ is perpendicular to plane M, it follows that PQ is the shortest segment from point P to plane M. This can be mathematically proven using the principles of geometry and the definition of perpendicularity.

The solution to the system equation  is (x, y, z, w) = (23, 12, 3, 1).

What is equation?

An equation could be a formula that expresses the equality of 2 expressions, by connecting them with the sign =

Main body:

Here is a system of linear equations that represents the situation.

x +5y +10z +20w = 133 . . . total amount earned

x +y +z +w = 39 . . . . . . . . . total number of bills

y = 4z . . . . . . . . . . . . . . . . . . the number of 5s is 4 times the number of 10s

x = 2y -1 . . . . . . . . . . . . . . . . the number of 1s is 1 less than twice the number of 5s

_____

We can substitute for x and z in the first two equations:

... (2y-1) +5y +10(y/4) +20w = 133

... (2y-1) +y +(y/4) +w = 39

These simplify to

... 9.5y +20w = 134

... 3.25y +w = 40

Solving by your favorite method, you get

... y = 12

... w = 1

So the other values can be found to be

... x = 2·12 -1 = 23

... z = 12/4 = 3

hence ,The solution to the system is (x, y, z, w) = (23, 12, 3, 1).

Answer:

Answer down below!

Step-by-step explanation:

Lets start off by finding a point we can start off at!

Since (2,0) lands perfectly on the number line, we can use that one!

From there, use the rise/run method to find your slope

We go up 2 and over -2

Thus our fraction is -2/2 BUT WE AREN'T DONE!

We can simplify this to be -1/1 or -1

Thus, our slope is -1

It's negative one, starting from the y intercept you're going down one right one and so on.

The closest option among the given choices is (D) 12.5%.To find the  percentage of students who could be expected to score between 70 and 90 on the standardized math exam.

We need to calculate the z-scores corresponding to these scores and then find the area under the normal distribution curve between these z-scores.

First, we calculate the z-score for a score of 70 using the formula:

z = (x - μ) / σ

where x is the score, μ is the mean, and σ is the standard deviation.

z1 = (70 - 100) / 60

z1 = -30 / 60

z1 = -0.5

Next, we calculate the z-score for a score of 90:

z2 = (90 - 100) / 60

z2 = -10 / 60

z2 = -0.1667

Now, we need to find the area under the normal distribution curve between these z-scores. This represents the percentage of students who would score between 70 and 90.

Using a standard normal distribution table or a calculator, we can find the area corresponding to each z-score:

Area between z1 and z2 = P(z1 < Z < z2)

From the standard normal distribution table, we find:

P(z1 < Z < z2) = P(Z < z2) - P(Z < z1)

P(Z < z2) = 0.4332

P(Z < z1) = 0.3085

Therefore, the area between z1 and z2 is:

0.4332 - 0.3085 = 0.1247

To convert this to a percentage, we multiply by 100:

Percentage = 0.1247 * 100 ≈ 12.47%

So, approximately 12.47% of the students can be expected to score between 70 and 90 on the standardized math exam.

There are 324 miles can Mario drive with 9 gallons of gas.

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

He can drive 18 miles on ½ a gallon of gas.

Now,

Since, He can drive 18 miles on ½ a gallon of gas.

Let the number of miles cover with 9 gallons of gas = x

So, By definition of proportion, we get;

⇒ 18 / (1/2) = x / 9

⇒ 18 × 2 = x / 9

⇒ 36 × 9 = x

⇒ x = 324 miles

Thus, The number of miles cover with 9 gallons of gas = 324 miles

Answer:

x = 8 , x = - 2

Step-by-step explanation:

the square of the number x is x² and 16 more than 6 times the number is 6x + 16 , then

x² = 6x + 16 ( subtract 6x + 16 from both sides )

x² - 6x - 16 = 0 ← in standard form

(x - 8)(x + 2) = 0 ← in factored form

equate each factor to zero and solve for x

x - 8 = 0 ⇒ x = 8

x + 2 = 0 ⇒ x = - 2

As a check

8² = 64 and 6(8) + 16 = 48 + 16 = 64 ← true

(- 2)² = 4 and 6(- 2) + 16 = - 12 + 16 = 4 ← true

then the required number is x = 8 or x = - 2
