Can someone help me figure out what is JK and LK

Mathematics
1 answer:
vivado [14]3 years ago
3 0

Answer:

JK = 10.524

LK = 21.065

Step-by-step explanation:

all angles in a triangle add up to 180, so angle K = 42.

law of sines states that \frac{A}{sin(a)} =\frac{B}{sin(b)} = \frac{C}{sin(c)}, where capital letters are side lengths and lower case letters are the angles opposite their corresponding capital letter sides.

in this case:

\frac{15}{sin(42)} = \frac{JK}{sin(28)} -----> JK = \frac{15sin(28)}{sin(42)} = 10.524

and

\frac{15}{sin(42)} = \frac{LK}{sin(110)} -----> LK = \frac{15sin(110)}{sin(42)} = 21.065

If a → b is true, then ~a → b is also true.
Rasek [7]

Answer:

False

Step-by-step explanation:

To determine whether the statemaent "If a\Rightarrow b is true, then \neg a\Rightarrow b is also true" holds, you can form the truth table:

\begin{array}{ccccc}a&b&a\Rightarrow b&\neg a&\neg a\Rightarrow b\\1&1&1&0&1\\1&0&0&0&1\\0&1&1&1&1\\0&0&1&1&0\end{array}

When the result of the column a\Rightarrow b takes value 1 (true), the result of the column  \neg a\Rightarrow b is not always 1, then the statement is false.

The dataset Restaurant Tips contains data recorded from 157 restaurant bills at a bistro in New York over a two week period and
xz_007 [3.2K]

Answer: ($3.532, $4.166)

Step-by-step explanation:

Given : Significance level : \alpha: 1-0.90=0.10

Critical value : z_{\alpha/2}=1.645

Sample size : n= 157

Sample mean : \overline{x}=\$\ 3.849

Standard deviation : \sigma= \$\ 2.421

The confidence interval for population mean is given by :_

\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

\text{i.e. }\$\ 3.849\pm (1.64)\dfrac{2.421}{\sqrt{157}}\\\\\approx\$\ 3.849\pm0.317\\\\=(\$\ 3.849-0.317,\$\ 3.849+0.317)=(\$\ 3.532,\$\ 4.166)

Hence, the 0% confidence interval for the average tip given at this restaurant = ($3.532, $4.166)
