Are triangles DEF and LNM similar if DF = 8 and LM = 4?

Komok [63]

We Cannot conclude that triangles DEF and LNM are similar if DF = 8 and LM = 4.

Solution:

Given that for two triangle DEF and LNM, DE = 8 and LM = 4.

To say that two triangles are similar the provided information is not complete.

Two triangles DEF and LNM , will be similar if there corresponding sides are in ratio which means

$\frac{\mathrm{DE}}{\mathrm{LM}}=\frac{\mathrm{EF}}{\mathrm{NM}}=\frac{\mathrm{EF}}{\mathrm{NM}}$

But we have only information of $\frac{\mathrm{DE}}{\mathrm{LM}}=\frac{8}{4}=2$

But do not have any information regarding two remaining ratios that are $\frac{\mathrm{EF}}{\mathrm{NM}} \text { and } \frac{\mathrm{EF}}{\mathrm{NM}}$

Hence cannot conclude that triangles DEF and LNM similar if DF = 8 and LM = 4

vredina [299]

Answer:

C. One can be 95% confident that the true proportion of all students receiving financial aid is between 0.52 and 0.66

Step-by-step explanation:

Given that the confidence interval is a term that defines a range of values with the probability to contain a population value that has an actual degree of confidence.

This is represented in a situation where population means falls in between upper and lower intervals.

Hence, in this case, the correct interpretation is option C: One can be 95% confident that the true proportion of all students receiving financial aid is between 0.52 and 0.66

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).

ZanzabumX [31]

Answer:

A= $8w^2+5w$

Step-by-step explanation:

We are given that John is building a rectangular pen for his sheep.\

We have to complete the given equation

Let w be the width of rectangular pen

According to question

Length of pen=8w+5

We know that

Area of rectangle= $Length \times breadth$

Using the formula

Area of rectangular pen= $w(5+8w)=8w^2+5w$

Therefore, the area of rectangular pen=A= $8w^2+5w$

Answer:

The value of the annuity in 10 years will be US$ 15,552.90

Step-by-step explanation:

Let's use the ordinary simple annuity formula to calculate the value of the annuity in 10 years, this way:

FV = Future value of an annuity stream

PMT = Dollar amount of each annuity payment = US% 50

r = Interest rate = 3.5% compounded biweekly = 0.035/26

n = Number of periods in which payments will be made = 26 * 10 = 260

FV = PMT * [(1 + r)ⁿ − 1]/r

Now, replacing with the real values, we have:

FV = 50 * [(1 + 0.035/26)²⁶⁰ − 1]/(0.035/26)

FV = 50 * [(1.001346154)²⁶⁰ − 1]/0.001346154

FV = 50 * 0.41873217/0.001346154

FV = 50 * 311.058148

FV = 15,552.90

We only rounded the last product to the next cent, in all the other cases we used all the decimals for the calculations.
