Draw an equilateral triangle of perimeter 10 centimetres.
Answer:
See attachment for triangle
Step-by-step explanation:
Given
Shape: Equilateral triangle
[tex]Perimeter = 10cm[/tex]
Required
Draw the triangle
First, we determine the side lengths.
The perimeter of an equilateral triangle is:
[tex]Perimeter = 3 * Length[/tex]
So, we have:
[tex]10= 3 * Length[/tex]
Solve for Length
[tex]Length = \frac{10}{3}[/tex]
[tex]Length = 3.33[/tex]

In the diagram, △NPQ ∼ △NLM and PL = 8.
a. Find the value of x
b. Find the lengths NP and NL, rounding to the nearest hundredth.
NP =
and NL =
Answer:
x = 14
NP = 3.66
NL = 8.01
Step-by-step explanation:
since △NPQ ∼ △NLM
<L = <P
3x + 18 = 60
3x = 60 - 18
3x = 42
x = 42/3
x = 14
Similarly;
PN/PL = QN/QM
y/8 = 3.2/7
Cross multiply
7y = 3.2* 8
7y = 25.6
y = 25.6/7
y = 3.66
Hence NP = 3.66
Also
NP/NQ = NL/NM
3.66/3.2 = NL/7
3.2NL = 7 * 3.66
3.2NL = 25.62
NL = 25.62/3.2
NL = 8.01
Two triangle are similar if they have the same ratio of the corresponding sides and equal pair of corresponding angle. The value of the x is 14 degrees, the length of the NP is 3.7 cm (round to the nearest hundred), and the length of the NL is 8 cm ( round to the nearest hundred).
Given information-The given tingle NPQ and triangle NLM are the similar triangle.
The length of the line PL is 8 cm.
Similar triangle-Two triangle are similar if they have the same ratio of the corresponding sides and equal pair of corresponding angle.
Value of the x-
As the two triangle are similar triangle, thus the length of the angle P is equal to the angle L. Therefore,
[tex]\angle L =\angle P\\ [/tex]
Keep the value of the angle from the diagram,
[tex]\begin{algined}\\ 3x+18&=60\\ 3x&=60-18\\\\ 3x&=42\\ x&=\dfrac{42}{3} \\ x&=14\\ \end[/tex]
Thus the value of the x is 14.
The length of the NP.
In the similar triangle the following ratios are equal,
[tex]\dfrac{PN}{PL} =\dfrac{QN}{QM} [/tex]
Put the values from the diagram,
[tex]\begin{aligned} \dfrac{y}{8}&=\dfrac{3.2}{7} \\ y&=\dfrac{3.2}{7} \times 8\\ y&=3.66\\ \end[/tex]
Value of y is equal to the length NP. Hence the length of the NP is equal to the 3.66 cm.
The length of the NL-
In the similar triangle the following ratios are equal,
[tex]\dfrac{NP}{NQ} =\dfrac{NL}{NM} [/tex]
Put the values from the diagram,
[tex]\begin{aligned} \dfrac{3.66}{3.2}&=\dfrac{NL}{7} \\ NL&=\dfrac{3.66}{3.2} \times 7\\ y&=8.01\\ \end[/tex]
Thus the length of the NL is equal to the 8.01 cm.
Hence the value of the x is 14 degrees, the length of the NP is 3.7 cm (round to the nearest hundred), and the length of the NL is 8 cm ( round to the nearest hundred).

Twenty nine concrete blocks were sampled and tested for crushing strength in order to estimate the proportion that were sufficiently strong for a certain application. Twenty seven of the 29 blocks were sufficiently strong. Use the small-sample method to construct a 95% confidence interval for the proportion of blocks that are sufficiently strong.
Answer:

A cell phone company is offering a plan for unlimited talk and text with an additional charge for data that can be represented by the function C(g) = 14.99g + 32, where C represents the cost, in dollars, and g represents the number of gigabytes of data, According to this model, fill in the blanks with the values that complete the sentence. The cost of the plan for unlimited talk and text is $ ______ , with an additional cost of $ ______ for each gigabyte of data.
This means that the extra cost for using 1 gigabyte of data will be $14.99, for using 2 gigabytes of data it will be $29.98, and so on.
What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
The given function C(g) = 14.99g + 32 represents the cost, in dollars, for a cell phone plan that offers unlimited talk and text, with an additional charge for data usage.
The function has two parts:
The fixed cost of the plan is $32 (this is the cost you pay even if you don't use any data).
The variable cost of the data usage is $14.99 per gigabyte.
So, the cost of the plan for unlimited talk and text is the fixed cost, which is $32.
And, the additional cost for each gigabyte of data is the variable cost, which is $14.99.
This means that if you use 1 gigabyte of data, the additional cost will be $14.99, if you use 2 gigabytes of data, the additional cost will be $29.98, and so on.

Intelligence Quotient (IQ) scores are often reported to be normally distributed with μ=100.0 and σ=15.0. A random sample of 51 people is taken. Step 1 of 2 : What is the probability of a random person on the street having an IQ score of less than 98? Round your answer to 4 decimal places, if necessary.
Answer:
0.4470 = 44.70% probability of a random person on the street having an IQ score of less than 98.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
What is the probability of a random person on the street having an IQ score of less than 98?
This is the pvalue of Z when X = 98. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{98 - 100}{15}[/tex]
[tex]Z = -0.1333[/tex]
[tex]Z = -0.1333[/tex] has a pvalue of 0.4470
0.4470 = 44.70% probability of a random person on the street having an IQ score of less than 98.

2. Solve the LP relaxation of the problem graphically. Round this solution to the nearest integer solution and check whether it is feasible. Then enumerate all the rounded solutions by rounding this solution for the LP relaxation in all possible ways (i.e., by rounding each non-integer value both up and down). For each rounded solution, check for feasibility and, if feasible, calculate z. Are any of these feasible rounded solutions optimal for the IP problem?
Answer:
See Annex
Step-by-step explanation:
The relaxation of any Linear Programming problem, consists of eliminating the integer constraint condition, keeping the original constraint and the objective function, solving the problem as continuous variables. If in such new condition we find that optimal solution consist of integer solution we have found optimal solution already, if not we need to go ahead with the branching procedure of making variables integer above and down of the fractional values.
In this particular case ( see GeoGebra graphic solution attached changing x₁ and x₂ by x and y respectively ), and Objective Function in red we got integer solution :
z(max) = 11
x₁ = x = 2
x₂ = y = 1

Suppose a normal distribution has a mean of 50 and a standard deviation of 3. What is P(x<53)?
A. 0.84
B. 0.16
C. 0.025
D. 0.975
The correct answer is A. 0.84
The value of P(X<53) is 0.84 if the Z = 1 and normal distribution has a mean of 50 and a standard deviation of 3 option (A) is correct.
What is a normal distribution?It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.
We know,
[tex]\rm Z = \dfrac{X-\mu}{SD}[/tex]
X = 53, μ = 50, and SD = 3
[tex]\rm Z = \dfrac{53-50}{3}[/tex]
Z = 1
From the Z table.
The value of P(X<53) = 0.84
Thus, the value of P(X<53) is 0.84 if the Z = 1 and normal distribution has a mean of 50 and a standard deviation of 3 option (A) is correct.
