Answers
Answer:
a=30 , b=60, c=105
Step-by-step explanation:
a=30 [Being vertically opposite angle]
Now,
a+b+90=180 [Being the sum of interior angles of a triangle]
or, 30+b+90=180
or, b+120=180
or, b=180-120
so, b= 60
Again,
c+75= 180 [Being linear pair]
or, c=180-75
so, c= 105

Why does this not exist? I thought if you plugged in infinity, you would just get infinity. Do you not plug in infinity?
Answers
Answer:
See below
Step-by-step explanation:
It does not exist because the

for ever
it exist when we have
[tex]\lim_{x\rightarrow \infty}[(\frac{1}{x})][/tex]

Miss Penny inherits £390.
She decides to save some of the
money and spend the rest.
The ratio of savings to spending
money is 9:4
How much does she save and how
much does she spend?
Answers
Answer:
£150 saved; £240 spent.
Step-by-step explanation:
If the ratio of savings to spending is 5:8, we find the fractions representing the amount saved and the amount spent by adding up 5 and 8 and then forming fractions:
savings: 5/13
spending: 8/13
(5/13) of £390 is £150; this is the amount saved.
(8/13) of £390 is £240; this is the amount spent.

Write an equation of the line passing through each of the following pairs of points. c (4, 0), (−2, 8)'
Answers
Answer:
Step-by-step explanation:
First, you must find the slope of the line using the formula (y2-y1/x2-x1). For your problem that would be (8-0/-2-4)= -4/3.
Then, you would plug in the slope and the y-intercept into the slope-intercept formula (y=mx+b), where m is the slope and b is the y intercept (4).
Your answer would be y=-4/3x+4

v=vo+at;find a if v = 20, vo = 30, t =5.
Answers
Answer:
-2 = a
Step-by-step explanation:
v = vo + at
20 = 30 + a5
now get the numbers and the variable on different sides
30 + a5 - 30 = a5
20 - 30 = -10
-10 = a5
now im going to divide each side by 5
a5 / 5 = a
-10 / 5 = -2
-2 = a
Step-by-step explanation:
[tex]V = V _{0} + at \\ 20 = 30 + a \times 5 \\ 5a = 20 - 30 \\ 5a = - 10 \\ \\ a = - \frac{10}{5} \\ \\ a = - 2[/tex]

Lee is a teacher at a local high school who wanted to assess whether or not dogs physically resemble their owners enough for people to be able to correctly match a dog to their owner better than if just guessing. Lee, who is also a dog owner, showed pictures of two dogs to her class of 16 students. One photo was of the teacher's dog (Yoda) and the other photo was of a dog the teacher had never met. The students were asked to guess which dog was actually the teacher's. If dogs do not physically resemble their owners, the students would get a correct match with probability 0.50. It turned out that 14 of the 16 students correctly picked out the teacher's dog.
Does it appear that the population proportion of people who can correctly match a dog to their owner (out of two options) is better than just guessing?
Answers
Answer:
The proportion of people who can correctly match a dog to their owner (out of two options) is better than just guessing.
Step-by-step explanation:
In this case we need to test whether the proportion of people who can correctly match a dog to their owner (out of two options) is better than just guessing.
The hypothesis can be defined as follows:
H₀: The proportion of people who can correctly match a dog to their owner is 50%, i.e. p = 0.50.
Hₐ: The proportion of people who can correctly match a dog to their owner is more than 50%, i.e. p > 0.50.
The information provided is:
[tex]x=14\\n=16[/tex]
The sample proportion is:
[tex]\hat p=\frac {x}{n}=\frac{14}{16}=0.875[/tex]
Compute the test statistic value as follows:
[tex]z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]=\frac{0.875-0.50}{\sqrt{\frac{0.50(1-0.50)}{16}}}\\\\=3[/tex]
The test statistic value is 3.
The decision rule is:
The null hypothesis will be rejected if the p-value of the test is less than the significance level.
Compute the p-value as follows:
[tex]p-value=P(Z>3)\\\\=1-P(Z<3)\\\\=1-0.99865\\\\=0.00135\\\\\approx 0.0014[/tex]
The p-value is, p-value = 0.0014.
The p-value of the test is very small for all the commonly used significance level. The null hypothesis will be rejected.
Thus, there is not enough evidence to support the claim.
Conclusion:
The proportion of people who can correctly match a dog to their owner (out of two options) is better than just guessing.
The double number line shows that 4 pounds of tomatoes cost $14. Draw tick marks and write labels to show the prices of 1, 2, and 3 pounds of tomatoes.
Answers
Answer:
every tick is 3.50
Step-by-step explanation:
14/4=3.5
The price of one, two, and three pounds of tomatoes is $10.5. Each quantity is represented by its own number line in a double number line, with corresponding pairs of values lined up.
How are double number lines created?Equal ratios are represented by two parallel number lines in a double number line diagram. The tick marks are in the same places on both number lines.Despite the fact that the other numbers change frequently, the tick marks labeled with 0 always line up.Diagrams with a double number line can show you how two quantities are related in terms of their ratios.They work best when the quantities have different units. (The unit rate is represented by the number 1) Students can more easily "see" that the same ratio can take many different comparable shapes when using double number line diagrams.Therefore,
Given,
4 pounds of tomatoes cost = $14
We find the prices of 1, 2, and 3 pounds of tomatoes
14/4 = 3.5
So,
1 lb = 3.5
2 lbs = 2× 3.5 = 7
3 lbs= 3 × 3.5 = 10.5
Hence, The price of one, two, and three pounds of tomatoes is $10.5.
