How to find the numeric value of a function or of an expression?To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.
The function for this problem is defined as follows:
d = 1.75h.
For the person with a height of 6 feet, the distance is obtained replacing the lone instance of h by 6, hence:
d = 1.75 x 6

In AOPQ, m/O = (6x – 14)°, m/P = (2x + 16)°, and m/Q = (2x + 8)°.
Find m/Q.
The required measure of angle m∠Q is 42 degrees, as of the given condition.
What is the triangle?The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should equal to 180°
Here,
In a triangle, the sum of the angles is always equal to 180 degrees. Therefore, for triangle OPQ,
m∠O + m∠P + m∠Q = 180°
Using the given information,
m∠O = (6x - 14)°
m∠P = (2x + 16)°
m∠Q = (2x + 8)°
(6x - 14)° + (2x + 16)° + (2x + 8)° = 180°
10x + 10 = 180°
10x = 170
x = 17
Substituting the value of x back into the expression for m∠Q,
m∠Q = (2x + 8)°
m∠Q = (2 * 17 + 8)°
m∠Q = 42°
So the value of m∠Q is 42 degrees.

when running Chao has a stride length of 70cm,correct to the nearet 5cm.
Chao runs a distance of 11.2 km, correct to the nearest 0.1km
work out the minumum number of stride that Chao could take to complete this distance
The minimum number of strides that Chao could take to complete a distance of 11.2 km is approximately 16,000.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
To calculate the minimum number of strides that Chao could take to complete a distance of 11.2 km, we need to first convert the distance to meters since the stride length is given in centimeters.
11.2 km = 11,200 meters (1 km = 1000 meters)
Stride length in meters = 70 cm / 100 cm/m = 0.7 m
Now, we can calculate the minimum number of strides as follows,
Minimum number of strides = (Distance covered in meters) / (Stride length in meters)
Minimum number of strides = 11,200 m / 0.7 m ≈ 16,000
Therefore, the minimum number of strides that Chao could take to complete a distance of 11.2 km is approximately 16,000.

The price of a Loungy Chair was $400. The price of this chair has just gone up by 20%. Make a percent table to find the new price of the Loungy Chair
The percent table is:
100 % ⇒ $400
120 % ⇒ $480
The initial price of the Loungy chair was $400.
So, the initial price(P₀) = $400
The price of the chair has gone up by 20%
So, increase in price(r) = 20%
The final price will be calculated by using the formula:
P = P₀(1 + r/100) (where P is the final price)
P = 400(1 + 20/100)
P = 400(1 + 0.2)
P = 400 × 1.2
P = $480

Mrs. Townsend is giving you a test worth 100 points and it contains 40 questions. There are two-point and four-point questions on the test. How many of each type of question are on the test?
Answer:
[tex]10[/tex] four point questions and [tex]30[/tex] two point questions
Step-by-step explanation:
Let's say [tex]f =[/tex] [tex]\text{number of four point questions}[/tex] and[tex]t = \text{number of two point questions}[/tex]. The total number of questions is [tex]40[/tex], therefore [tex]t + f = 40[/tex]. We know the test is worth [tex]100[/tex] points so we can write [tex]2t + 4f = 100[/tex]. We have a system of equations: [tex]t + f = 40 \text{ and } 2t + 4f = 100[/tex]. We can rewrite [tex]t[/tex] as [tex]t = 40 - f[/tex]. We rewrite this in the equation [tex]2t + 4f = 100[/tex]. Since [tex]t = 40 - f[/tex], we have [tex]2 \cdot (40 - f) + 4f = 100[/tex]. Distributing & simplifying gives
[tex]2 \cdot (40 - f) + 4f = 100\\(80 - 2f) + 4f = 100,\\\text{Remove parentheses} 80 - 2f + 4f = 100,\\80 + (-2f) + 4f = 100\\80 + 2f = 100,\\\text{Subtract 80 from both sides} 2f = 20,\\\text{Divide 2 by both sides} f = 10.\\[/tex]
Since we determined [tex]t = 40 - f[/tex] and [tex]f = 10[/tex], subtracting [tex]10[/tex] from [tex]40[/tex] will give [tex]t = 30[/tex].
Therefore, there are [tex]10[/tex] four point questions and [tex]30[/tex] two point questions.

The corresponding p-value for this test statistic is 0.005, which is smaller than our significance level of α=0.05.
To begin, we define the population proportion of people who shop for groceries online in region A as p₁ and the population proportion of people who shop for groceries online in region B as p₂.
Our null hypothesis is that there is no difference in these proportions, which we can write as H0=> p₁ = p₂. Our alternative hypothesis is that there is a difference, which we can write as H1=> p₁ ≠ p₂.
Next, we need to calculate the sample proportions and standard errors for each region. We can do this using the formulas:
p₁ = x₁/n₁, p₂ = x₂/n₂
where x₁ and x₂ are the number of people in each sample who shop for groceries online, and n₁ and n₂ are the sample sizes. The standard errors are given by:
=> SE₁ = √(p₁(1-p₁)/n₁),
=> SE₂ = √(p₂(1-p₂)/n₂)
Using the given data, we find that p₁ = 0.16, p₂ = 0.24, SE₁ = 0.037 and SE₂ = 0.042.
We can now calculate the test statistic, which measures the difference between the sample proportions under the assumption that the null hypothesis is true. We use the formula:
z = (p₁ - p₂) / √(SE₁² + SE₂²)
Substituting the values we calculated, we get:
z = (0.16 - 0.24) / √(0.037² + 0.042²) = -2.83
