The 95% confidence interval for the effectiveness of the blood-pressure drug is given as follows:

\(22.6 < \mu < 24.4\)

The mean, the standard deviation and the sample size for this problem, which are the three parameters, are given as follows:

\(\overline{x} = 23.5, \sigma = 12.2, n = 775\)

Looking at the z-table, the critical value for a 95% confidence interval is given as follows:

z = 1.96.

The lower bound of the interval is then given as follows:

\(23.5 - 1.96 \times \frac{12.2}{\sqrt{775}} = 22.6\)

The upper bound of the interval is then given as follows:

\(23.5 + 1.96 \times \frac{12.2}{\sqrt{775}} = 24.4\)

Answer:

Step-by-step explanation:

the problem that would have to be plugged into the calculator would be as following

Answer:

The original price of the shoes was $53.

The discount percentage was 20%.

The discount amount was 53 * 0.2 = 10.6.

The sale price after the discount was 53 - 10.6 = 42.4.

The processing fee percentage was 20%.

The processing fee amount was 42.4 * 0.2 = 8.48.

The final price after the processing fee was 42.4 + 8.48 = 50.88.

Therefore, the discount was $10.60, and the final price was $50.88.

Answer:

Probability that first sock is blue is 0.33 and Probability that second sock is red is 0.16

Step-by-step explanation:

Number of red socks = 2

Number of white socks = 6

Number of blue socks = 4

Total socks in drawer = 2+6+4 = 12

The formula used to calculate probability is: \(Probability=\frac{Number \ of \ favourable \ outcomes}{Total \ number \ of \ outcomes}\)

We are given you draw out a  sock, return it, and draw out a second sock.

We need to find the probability that the first sock is blue and the  second sock is red?

Using formula:

Probability that first sock is blue = 4/12 = 1/3 = 0.33

Probability that second sock is red = 2/12 = 1/6 = 0.16

So, Probability that first sock is blue is 0.33 and Probability that second sock is red is 0.16

Answer:

y=4x+9

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(1-(-11))/(-2-(-5))

m=(1+11)/(-2+5)

m=12/3

m=4

y-y1=m(x-x1)

y-(-11)=4(x-(-5))

y+11=4(x+5)

y=4x+20-11

y=4x+9

Step-by-step explanation:

The equation of the line of best fit for the given data is Y = 0.979X + 1.722

We can use the following formula to calculate the slope of the line of best fit:

slope = (N∑XY - ∑X∑Y) / (N∑X² - (∑X)²)

where N is the number of data points, ∑X represents the sum of all X values, ∑Y represents the sum of all Y values, ∑XY represents the sum of the product of X and Y values, and ∑X² represents the sum of all squared X values.

Using the given data, we can plug in the values into the formula to get:

slope = (5(4)(5) + 7(7)(7) + 10(12)(10) + 12(14)(12) + 13(18)(13) - (4+7+10+12+13)(5+7+12+14+18)) / (5(4²) + 7(7²) + 10(10²) + 12(12²) + 13(13²) - (4+7+10+12+13)²)

slope = 0.979

Next, we can use the following formula to calculate the y-intercept of the line:

y-intercept = y - slope(x)

where y represents the mean of all Y values, x represents the mean of all X values, and slope represents the slope of the line of best fit that we just calculated.

Using the given data, we can calculate the mean of X and Y values as follows:

x = (4 + 7 + 10 + 12 + 13) / 5 = 9.2 y = (5 + 7 + 12 + 14 + 18) / 5 = 11.2

Now, we can plug in the values into the formula to get:

y-intercept = 11.2 - 0.979(9.2)

y-intercept = 1.722

Therefore, the equation of the line of best fit for the given data is:

Y = 0.979X + 1.722

Step-by-step explanation:

a prime polynomial is one which does not factor into 2 binomials.

its only factors are 1 and itself

attempt to factorise the given polynomials

3x³ + 3x² - 2x - 2 ( factor the first/second and third/fourth terms )

= 3x²(x + 1) - 2(x + 1) ← factor out common factor (x + 1) from each term

= (x + 1)(3x² - 2) ← in factored form

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

3x³ - 2x² + 3x - 4 ( factor the first/second terms

= x²(3x - 2) + 3x - 4 ← 3x - 4 cannot be factored

thus this polynomial is prime

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

4x³ + 2x² + 6x + 3 ( factor first/second and third/fourth terms )

= 2x²(2x + 1) + 3(2x + 1) ← factor out common factor (2x + 1) from each term

= (2x + 1)(2x² + 3) ← in factored form

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

4x³ + 4x² - 3x - 3 ( factor first/second and third/fourth terms )

= 4x²(x + 1) - 3(x + 1) ← factor out common factor (x + 1) from each term

= (x + 1)(4x² - 3) ← in factored form

Class  4,8,12,16

Chess 2,4,6,8,10,12

Fencing 3,6,9,12

Starting today at week 0, he will attend all 3 again at week 12

Answer:

12 weeks

Step-by-step explanation:

We know that Salvatore attends class every 4 week, chess club every 2 weeks, and fencing lessons every 3 weeks.

If he attended all today, to find out when he will attend all again,we just need to find the least common multiple (LCM) of 3, 4, and 2.

The LCM of 3, 4, and 2 is 12.

So, he will attend all classes again after 12 weeks.

Answer:

The value of x is 7

Step-by-step explanation:

Complementary angles have a sum of 90°, therefore the equation to solve for x is:

∠1+∠2=90°

60°+5(x-1)°=90°

5(x-1)=30°

x-1=6

x=7

So the value of x is 7

Step-by-step explanation:

The triangle ∠ADC is a central angle, m∠ADC is 60 degrees, and m∠ABC is 30°.

The central angle is the angle that a circle's arc occupies in its centre. The arms of the central angle are formed by the radius vectors. In other terms, it is an angle whose vertex is the centre of a circle, with the two radii lines acting as its arms and intersecting the circle at two distinct places. These two points make an arc when they are coupled together. The angle that this arc at the circle's centre subtends is called the central angle.

Half of the central angle is the circumferential angle.

∠ABC is equal to 1/2 of ∠ABC.

∠ABC = \(\frac{1}{2}*60\)

∠ABC = 30°

Option b. 30° is the right response, so.

Answer:

y-1= -1/3(x+3)

Step-by-step explanation:

y-y1=m(x-x1)

y-1=m(x+3)

the slope is rise over run

the slope is -1/3

Answer:

y - 1 = 3/2 (x + 3)

Step-by-step explanation:

To find the equation of a line parallel to the given line and passing through the point (-3, 1), we can use the point-slope form of a linear equation. The point-slope form is given by:

y - y₁ = m(x - x₁)

Where (x₁, y₁) is the given point and m is the slope of the line.

First, let's calculate the slope of the given line using the two points (-2, -4) and (2, 2):

slope = (y₂ - y₁) / (x₂ - x₁)

= (2 - (-4)) / (2 - (-2))

= 6 / 4

= 3/2

Since the line we want to find is parallel to the given line, it will have the same slope. Therefore, the slope (m) of the new line is also 3/2.

Now we can substitute the values into the point-slope form using the point (-3, 1):

y - 1 = (3/2)(x - (-3))

y - 1 = (3/2)(x + 3)

The equation in point-slope form of the line parallel to the given line and passing through the point (-3, 1) is:

y - 1 = 3/2 (x + 3)

The graph of the function y = -2x + 1/3 is added as an attachment

From the question, we have the following parameters that can be used in our computation:

y = -2x + 1/3

The above function is a linear function that has been transformed as follows

Next, we plot the graph using a graphing tool by taking not of the above transformations rules

The value of XZ is given by 26.

Given that the triangles RST and XYZ are congruent to each other.

So, RS = XY, since corresponding parts of Congruent triangles are equal.

Given also that,

RS = 11x-1

XY = 9x+5

XZ = 7x+5

So, RS = XY gives

11x-1 = 9x+5

11x-9x = 5+1

2x = 6

x = 6/2

x = 3

Substituting the value of x in the value of XZ is given by,

XZ = 7x+5 = 7*3+5 = 21+5 = 26
