Tiffany surveyed some of her classmates to find the number of times they wrote the weekly spelling words. She also found the number of words they missed on the spelling test. The scatterplot shows the results of Tiffany’s survey. Which statement does NOT match Tiffany’s scatterplot?
Options :
A.) A student who missed 2 words on the test wrote each word 4 times.
B.) A student who wrote each word once missed 6 words on the test.
C.) A student who did not write the words missed 8 words on the test.
D.) A student who missed 4 words on the test wrote each word 3 times.
Answer:
A student who did not write the words missed 8 words on the test.
Step-by-step explanation:
From the scatter plot, we could identify all the other points except that of option C.
For option A : (4, 2) is a marked point on the graph
For option B : (1, 6) is also a marked point on the graph
For option C : (0, 8) is not a marked point on the graph and hence, does not match Tiffany's scatter plot.

9. In a rhombus whose side measures 34 and the smaller angle is 42°. Find the length of the larger diagonal, to the nearest tenth.
Answer:
63.5
Step-by-step explanation:
The diagonals of a rhombus bisect opposite angles.
The longer diagonal bisects the 42° angle
The larger angle of the rhombus is 180 - 42 = 138
Let x = the length of the longer diagonal
You know two sides and the included angle of a triangle.
Using the law of cosines we get
[tex]x^{2} = 34^{2} + 34^{2} -2(34)(34) cos 138\\ = 1156 + 1156 - 2312 cos 138\\ = 4030.150837...\\x = \sqrt{4030.150837} = 63.48[/tex][tex]x^{2} = 34^{2} + 34^{2} -2(34)(34)cos 138\\ = 1156 + 1156 - 2312 cos 138\\ = 4030.1508...\\ x = \sqrt{4030.1508} \\ = 63.48[/tex]x^2 = 34^2 + 34^2 - 2(34)(34) cos 138
= 1156 + 1156 - 2312 c0s 138
= 4030.1508...
x = sq rt 4030.1508...
= 63.5

Let p and q represent the following simple statements:
p: The taxes are high.
q: The job pays well.
Write the following compound statement in its symbolic form.
The taxes are high and the job pays well.
The symbolic form is
Answer: [tex]p \ \wedge \ q[/tex]
The upside down V symbol is known as a wedge. It represents a conjunction which is informally the "and". In other words, [tex]p \ \wedge \ q = \text{p and q}[/tex]
Note how we can replace p with "the taxes are high" and replace q with "the job pays well" to arrive at the overall compound statement "The taxes are high and the job pays well".
Some logic textbooks will use an ampersand symbol & to be used in place of a wedge. It will depend on the notation that they, or your teacher, has set up.

(1 point) Dylan wants to determine a 99 percent confidence interval for the true proportion p of high school students in the area who attend their home basketball games. Out of n randomly selected students he finds that that exactly half attend their home basketball games. About how large would n have to be to get a margin of error less than 0.01 for p
Answer:
n would have to be at least 16577
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
Out of n randomly selected students he finds that that exactly half attend their home basketball games.
This means that [tex]\pi = 0.5[/tex]
99% confidence level
So [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].
About how large would n have to be to get a margin of error less than 0.01 for p
A sample size of n is needed. n is found when M = 0.01. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.01 = 2.575\sqrt{\frac{0.5*0.5}{n}}[/tex]
[tex]0.01\sqrt{n} = 2.575*0.5[/tex]
[tex]\sqrt{n} = \frac{2.575*0.5}{0.01}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.575*0.5}{0.01})^2[/tex]
[tex]n = 16576.6[/tex]
Rounding up
n would have to be at least 16577
When the error margin is smaller than 0.01, the value of n will be 16576.6.
What is a confidence interval?The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval.
Given that;
Confidence interval = 99 %
Randomly selected students,n
margin of error,M0.01
The margin of error for the given information is;
[tex]\rm M = z \frac{\sigma(1-\sigma)}{n} \\\\\ 0.01 = 2.575 \frac{0.5(0.5)}{n} \\\\ 0.01 \sqrt n = 2.575 \times 0.5 \\\\ \sqrt n = \frac{2.575 \times 0.5}{0.01} \\\\ n = 16576.6[/tex]
Hence, the value of n for which the margin of error is less than 0.01 will be 16576.6.

Write an exponential function to model the following situation: A population starting at 740 animals
decreases at an annual rate of 12%. Use your function to determine about how many animals there will
be after 5 years.
A. 390
B. 150
CC. 680
D. 340
Answer:
A. 390
Step-by-step explanation:
An exponential function can be written in the form [tex]f(n)=a\times b^n[/tex], where [tex]a[/tex] is your starting population, [tex]b[/tex] is the factor by which the population increases, and [tex]n[/tex] is the number of terms. In this case, [tex]a=740[/tex], [tex]b=0.88[/tex] because the population decreases by 12 percent (1-0.12=0.88), and [tex]n=5[/tex].
Thus, [tex]f(5)=740 \times 0.88^5[/tex], which is roughly equal to 390.
