can somebody explain how to do this?

Answer:

11.25 miles

Step-by-step explanation:

Given that,

No of days for which Jocelyn walks is 5

Each walk is \(2\dfrac{1}{4}\) miles long

We need to find the distance traveled by her each week.

Total distance = Distance per walk × days

\(=2\dfrac{1}{4}\times 5\\\\=\dfrac{9}{4}\times 5\\\\=11.25\ \text{miles}\)

Hence, she will cover 11.25 miles.

Answer:

Step-by-step explanation:

The point on the line that passes through point H and is perpendicular to line FG is (–6, 10).

First, we need to find the slope of line FG. The slope of a line can be calculated by dividing the change in the y-coordinate by the change in the x-coordinate. In this case, the change in the y-coordinate is 10 and the change in the x-coordinate is 3, so the slope of line FG is 10/3.

Since the lines are perpendicular, their slopes are negative reciprocals of each other. The negative reciprocal of 10/3 is -3/10.

Now, we need to find the equation of the line that passes through point H and has a slope of -3/10. The general equation of a line is y = mx + b, where m is the slope and b is the y-intercept. In this case, we know that m = -3/10 and the y-coordinate of point H is 10. Plugging these values into the equation, we get y = -3/10*x + 10.

To find the x-coordinate of the point we are looking for, we can substitute in the y-coordinate of point H. 10 = -3/10*x + 10, so x = –6.

Therefore, the point on the line that passes through point H and is perpendicular to line FG is (–6, 10).

Step-by-step explanation:

The equation of the circle is (x + 1)² + (y + 3)² = 6². When we plug in (-6, -6) we get (-6 + 1)² + (-6 + 3)² = 6², which is a true statement so that means that the point is on the circle.

The probability that exactly 6 patients is 2.0669, and the probability that at least 2 patients is 0.0017.

In large restaurants, an average of 3 out of every 5 customers ask for water with their meal. A random sample of 10 customers was selected. We need to estimate the probability that exactly 6 patients and at least 2 patients. The given situation is a binomial distribution since the experiment has only two outcomes, success or failure.

Here, Success is defined as requesting water with a meal, and failure as not requesting water with a meal. The probability of success is p = 3/5 = 0.6 and the probability of failure is q = 1 - p = 1 - 0.6 = 0.4. Let X be the number of patients requesting water with a meal out of 10 patients selected.

P(X = 6) = 10C6 (0.6) (0.4)⁴

= 210 × 0.31104 × 0.0256

= 2.0669P(X ≥ 2)

= P(X = 2) + P(X = 3) + .... + P(X = 10)P(X ≥ 2)

= 10C2 (0.6)² (0.4)⁸ + 10C3 (0.6)³ (0.4)⁷ + ..... + 10C10 (0.6)¹⁰ (0.4)⁰ P(X ≥ 2)

= 0.0022 + 0.0185 + 0.0881 + 0.2353 + 0.3454 + 0.2508 + 0.0986 + 0.0180 + 0.0016P(X ≥ 2)

= 1 - P(X < 2)P(X < 2) = P(X = 0) + P(X = 1)P(X < 2)

= 10C0 (0.6)⁰ (0.4)¹⁰ + 10C1 (0.6)¹ (0.4)⁹ P(X < 2)

= 0.0001 + 0.0016P(X < 2)

= 0.0017

The length of XZ in circle C is equal to the √34. This can be found using the Pythagorean theorem and the fact that XZ is a radius of the circle.

As WZ and XR are diameters, they intersect at the center of the circle, which we'll call point O.

Since WX is a chord of the circle, we can use the perpendicular bisector of WX, which passes through O, to find the length of XZ.

Let's call the midpoint of WX point M. Then OM is perpendicular to WX and bisects it.

So we have two right triangles, OXM and MXZ. We know that OM = 5 and XM = 3 (half of WX).

Using the Pythagorean theorem, we can find the length of OX:

OX² = OM² + MX²

OX² = 5² + 3²

OX² = 34

OX = √(34)

Since XZ is also a radius of the circle, we have XZ = OX = √(34).

Therefore, the measure of XZ in circle C is √(34).

Performance relative to the whole class refers to an individual's academic achievement in comparison to the rest of their peers in a particular subject or course.

We describe performance relative to the whole class.

To do this, we'll be using the terms "average", "percentile rank", and "standard deviation".
Average:

Calculate the average performance of the whole class by adding all students' scores and then dividing by the number of students.

This will give you a baseline to compare individual performances against the class average.
Percentile Rank:

Determine the percentile rank of a student by calculating the percentage of students in the class who scored lower than them.

For example, if a student is in the 75th percentile, it means they performed better than 75% of the class.
Standard Deviation:

Calculate the standard deviation, which measures the spread of scores within the class.

A low standard deviation indicates that most students have similar performances, while a high standard deviation shows more variability in scores.
By considering these three factors, you can effectively describe a student's performance relative to the whole class. For example, you might say: "John scored above the class average, placing him in the 80th percentile with a moderate standard deviation, indicating that his performance is better than the majority of his classmates."

For similar question on standard deviation.

The total capacity of the big school bus is 140 children.

To find out how many children can fit into the big school bus, let's work through the given information step by step.

When the bus left Area A, it was 2/7 full. This means that 2/7 of the bus's capacity was occupied by children. Let's represent the total capacity of the bus as 'x'. Therefore, 2/7 of 'x' corresponds to the number of children on the bus when it left Area A.

After the bus arrived at Area B, 9 children alighted, which means the number of children decreased by 9. We are then told that there were 31 children remaining on the bus. So, the number of children on the bus before any alighted was 31 + 9 = 40.

Since 2/7 of the bus's capacity was occupied by children when it left Area A, we can set up the following equation:

(2/7) * x = 40

To solve for 'x', we can multiply both sides of the equation by (7/2):

x = 40 * (7/2)

x = 140

Therefore, the total capacity of the big school bus is 140 children.

The translation in y = (x + 3)² is of 3 units to the left. The correct option is the last one.

For a general function y = f(x), we define a horizontal translation of N units as:

g(x) = f(x + N)

Here the original function is y = x² and the translated one is:

y = (x + 3)²

So we just added 3 on the argument, so this is a shift of 3 units to the left, the correct option is the last one.

Sonji choses the pieces that can be used to construct a triangle.

Given the question is shown in attached image.

We have to find which student chose pieces that can be used to construct a triangle.

Here, we will use the third important property of triangles is the triangle inequality rule, which states that the one length of a side of a triangle is always less than the sum of the lengths of the other two sides which are left and greater than the difference of the lengths of the other two sides.

So, applying this property in each case:

Case 1. Don’s uses the wires which measure 3 inches, 5 inches, and 12 inches.

Now using property

since sum of two sides = 3+5 =8

As we see here the third side 12 is not less than 8

So, Don’s wire cannot be used .

Case 2. Margo’s uses the wires which measure 6 inches, 8 inches, and 14 inches.

Now using property

since sum of two side :8+6=14

But third side 14 is not less than 14

So, Margo’s wire cannot be used .

Case 3. Sonji’s uses the wires which measure 12 inches, 8 inches, and 17 inches.

Now using property

since sum of two side :12+8=20

third side 17 is  less than 20

Now , difference of two sides : 12-8=4

third side 17 is greater than 4

So, Sonji’s wire can be used .

Case 4. Liam’s uses the wires which measure 16 inches, 8 inches, and 27 inches.

Now using property

since sum of two side :16+8 =24

But third side 27 is not less than 24

So, Liam’s wire cannot be used .

Hence, according to the question sonji choses the pieces that can be used to construct a triangle which is shown in attached image.

Answer:

f(x) = x^2 - 4x - √5

Step-by-step explanation:

A polynomial function of least degree with rational coefficients, a leading coefficient of 1, and zeroes at 4 and -√5 can be written as:

f(x) = (x - 4)(x + √5)

This is a polynomial of degree 2 (a quadratic), and it has rational coefficients as it is made up of two binomials, both of which have integers as their coefficients. The leading coefficient is 1, and the zeroes are at 4 and -√5.

In standard form, f(x) = ax^2 + bx + c, we can write it as

f(x) = x^2 - 4x - √5

Note that the above polynomial uses irrational numbers, which are not rational coefficients, but it has zeroes at the given value of 4 and -√5.
