Answer:

2 standard deviations of the mean. so, 41 to 65

Step-by-step explanation:

from the empirical rule we know that for 95% we are in 2 standard deviations of the mean. so:

53- 6- 6 = 41

*2 minus 6s because 2 standard dev. with the mean

53 + 6 + 6 = 65

Answer:

[tex]\#\text{ of 8-onion bags: }4,\\\#\text{ of 3-onion bags: }3[/tex]

Step-by-step explanation:

Let [tex]a[/tex] be the number of bags with 8 onions and let [tex]b[/tex] be the number of bags with 3 onions. We have the following system of equations:

[tex]\begin{cases}a+b=7,\\8a+3b=41\end{cases}[/tex]

Subtracting [tex]b[/tex] from both sides of the first equation, we get [tex]a=7-b[/tex]. Substitute this into the second equation:

[tex]8(7-b)+3b=41,\\56-8b+3b=41,\\56-5b=41,\\-5b=-15,\\b=\boxed{3}[/tex]

Therefore, the number of 8-onion bags is:

[tex]a=7-b,\\a=7-3,\\a=\boxed{4}[/tex]

Thus, the chef got 4 8-onion bags and 3 3-onion bags.

In geometry, an angle is formed when two rays are joined at their endpoints. These rays are called the sides or arms of the angle. Let us read about the different parts of an angle.

Parts of an Angle

There are two main parts related to an angle - the arms and the vertex.

Arms of the Angle

The two rays which join at a common point to form the angle are called the arms of the angle. Observe the figure given below which shows that OA and OB are the arms of the angle AOB.

<DEF=149

let <DEG be x

So,<GEF = 5x-13

Now

5x-13+x=149

6x=162

x=27

Hence, <GEF = 5(27)-13= 122

Answer: 4.5cm

Step-by-step explanation:

From the information given in the question, we are informed that an airport runway measuring 450 m is drawn to a scale of 1 cm represent 100m, then the length in the drawing will be calculated thus:

Let the length be represented by x. Therefore, we'll have:

1/x = 100/450

Cross multiply

(100 × x) = (1 × 450)

100x = 450

x = 450/100

x = 4.5

Therefore, the length in the drawing is 4.5cm

Answer: B. (x - 1) (x - 4)

Concept:

Here, we need to know the idea of zeros.

The zeros of a quadratic equation are the points where the graph of the quadratic equation crosses the x-axis.

If you are still confused, please refer to the attachment below for a graphical explanation.

Solve:

By definition, the factored form of quadratic equations is basically their zeros.

STEP ONE: Find the zeros / x-intercept of the graph

The grid number is 2 per grid as 5 grids are 10 units.

The first intercept is between the y-axis and the first grid.

The second intercept is on the second grid.

STEP TWO: Plug the zeros into factorization form

Factor form = (x - x₁) (x - x₂)

x₁ = (1, 0)

x₂ = (4, 0)

Factorization of x² - 5x + 4 = (x - 1) (x - 4)

Complete question is;

Determine whether the experiment is blind or double blind.

Is the aspirin produced by the World’s Best Pharmaceutical Company better than that of a competitor at relieving headaches? 200 headache sufferers are chosen at random. Migrained Testing Service administers the experiment and provides the results evaluation. Three levels are made: participants receive contents from Bottle A, Bottle B, or Bottle C. Other than the fact that one bottle contains placebo aspirin, no other information is given to the testing service regarding the bottles’ contents.

a) blind study

b) double blind study

C) Neither

Answer:

Double blind study.

Step-by-step explanation:

We are told that participants receive contents from Bottle A, Bottle B, or Bottle C.

However, the testing service only knows that one bottle contains placebo aspirin but they don't know the other contents nor which of the participants is taking the one with placebo aspirin.

Thus, this is a double blind experiment because neither the participants nor the testing service have knowledge of who is taking the bottle that contains placebo aspirin unlike a blind experiment where the testing service will know which participants got the bottle containing aspirin.

Answer:

10 ring boxes

Step-by-step explanation:

First, we need to calculate the total surface area of each cube ring boxes

The surface area of each square boxes = 6L²

Given that L =1.5inches

Total surface area = 6(1.5)²

Total surface area = 6(2.25)

Total surface area = 13.5in²

Since the question is incomplete. Let us assume the total surface area of the shipping box is 135in²

Number of ring boxes he can ship = 135/13.5

Number of ring boxes he can ship = 10

Hence the number of ring boxes he can ship is 10 ring boxes

NB: The total surface area of the shipping box was assumed

solution given;

36:5/5

38:86/69

To divide fractions, you basically just multiply the first fraction by the reciprocal of the second. To find the reciprocal, you just flip the numerator and the denominator.

For number 36, you have 2/3÷8/15. To solve this, you just multiply 2/3 by 15/8.

2/3×15/8 is 30/24, which is 5/4 or 1 1/4.

To answer the second problem, you have to convert the mixed numbers to improper fractions.

7 1/6 as an improper fraction is 43/6. 5 3/4 as an improper fraction is 23/4.

Do the same procedure; 43/6×4/23 is 86/69 or 1 17/69.

Answer:

-1/2

Step-by-step explanation:

- arrange the equation in the y=mx+b form

2x + 4y =21, subtract 2x from both sides of the equation

4y= -2x +21 , divide both sides by 4

y= -1/2x +21/4

-compare the slopes m of the 2 equations

y= kx -12, has the slope k

y= -1/2x +21/4, has the slope -1/2

- If the lines are parallel then they have the same slope

Therefore, k= -1/2

Answer:

use the distance formula to find the diameter of the circle.  From there, you can divide the diameter in half to find the radius of the circle

Step-by-step explanation:

so... the distance formula is...

d = [tex]\sqrt{(x_{2} - x_1)^{2}+(y_2 - y_1)^{2} }[/tex]

so...you just substitute the values into the equation

d = [tex]\sqrt{(-4-4)^2 + (-3-3)^2}[/tex]

d = [tex]\sqrt{64+36}[/tex]

d = 10

so...that means the diameter is 10

to find the radius you do 10/2 because radius is half of the diameter

so the radius is 5

hope that helps...that took so long to write out

Answer:

a₁₁ = 37

Step-by-step explanation:

There is a common difference between consecutive terms, that is

1 - (- 3) = 5 - 1 = 9 - 5 = 13 - 9 = 4

This indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 3 and d = 4 , then

a₁₁ = - 3 + (10 × 4) = - 3 + 40 = 37

Answer:

x=2

Step-by-step explanation:

A line that intersects a circle in two points is called a secant line, and this is the case for both line DE and AE.

For two secant lines that intersect outside of the circle, such as the ones here, we can say that

CE * DE = BE * AE

Therefore, we need to then define these lines.

CE is x+4, BE is x+1, AE = (BE + AB) = 11+x+1 = 12+x, and DE = (CE + DC) = 1+x+4 = 5+x

We then have

(x+4) * (5+x) = (x+1) * (12+x)

expand

5x + x² + 20 + 4x = 12x+x²+12+x

x²+9x + 20 = x²+13x+12

Next, we want to congregate all values to one side so we can solve for x. This can be done by subtracting both sides by (x²+13x+12) to get

-4x + 8 = 0

subtract 8 from both sides to isolate the x and its coefficient

-4x = -8

divide both sides by -4 to isolate the x

x = 2

Answer:

c) The golf ball will travel 260.8 yards.

d) Hence the residual is 4.2 yards.

Step-by-step explanation:

c) y' = 2.8333x - 22.4967

Now the golf ball will travel [tex]= 2.8333\times100 - 22.4967[/tex]= 260.8 yards

here y'= 260.8 yards.

d) The residual is : y - y' = 265 - 260.8 = 4.2 yards.

Answer:

a)  [tex]y=260.8333~yd[/tex]

b) [tex]\Delta d=4.1667~yd[/tex]

c) [tex]y=260~yd[/tex]

d) [tex]\Delta y'=0.8333~yd[/tex]

Step-by-step explanation:

Given:

equation of line, [tex]y=2.8333x-22.4967[/tex]

x = club-head speed​ (in miles per​ hour)

y = the distance a golf ball travels​ (in yards)

a)

x = 100 mph

Then the distance travelled by the ball:

(put the given value of x in the above eq.)

[tex]y=2.8333\times 100-22.4967[/tex]

[tex]y=260.8333~yd[/tex]

b)

If the observed distance in the above case comes out to be 265 yards then the residual value will be:

[tex]\Delta d=265-260.8333[/tex]

[tex]\Delta d=4.1667~yd[/tex]

c)

From the calculated value when rounding it to the nearest tenth:

[tex]y=260~yd[/tex]

d)

The residual on rounding the calculated value to the nearest tenth:

[tex]\Delta y'=260.8333-260[/tex]

[tex]\Delta y'=0.8333~yd[/tex]

Step-by-step explanation:

The experimental probability that the number cube shows 4 is 2/7.

Experimental probability is a probability that is determined on the basis of a series of experiments.

Given that, a number cube is rolled 14 times, we need to determine the experimental probability that the number cube shows 4,

The formula to calculate the experimental probability is:

P(E) = Number of times an event occurs/Total number of times the experiment is conducted

P(E) = 4/14 = 2/7

Hence, the experimental probability that the number cube shows 4 is 2/7.
