Answer:
Less
Step-by-step explanation:
Working with the information provided, we are to determine whether Cameron obtained via exchange more or less on his second trip to Canada. While the time frame for this would help, it's likely that it isn't offered to you, so I'm going to try and simplify.
He would receive less, as the inflation rate in America is higher than in Canada, meaning U.S dollars depreciate in value faster.

Answer:
Step-by-step explanation:
Formula: Scored Marks/Out of Marks × 100 = result %
( 37 ÷ 50 ) x 100 = 74%
Hope this Helps!!!!
Answer:
the answer is C)13
Step-by-step explanation
50x2=100. 74% of 100 is 74 which leaves 26. 26/2 is 13

x=12 cos 36
x=12/cos 36
x=12 sin 54
x= 12/sin54
Answer:
If you have the hypotenuse, multiply it by sin(θ) to get the length of the side opposite to the angle. Alternatively, multiply the hypotenuse by cos(θ) to get the side adjacent to the angle. If you have the non-hypotenuse side adjacent to the angle, divide it by cos(θ) to get the length of the hypotenuse.

You can get the area of each square by taking 8*6 = 48. There are 2 of them so that would so far equal 96.
To get the triangles, we can subtract 15-8 to get 7, which is the base of 1 triangle. 7*6/2 to get the area of one triangle is 21. Since there are 4 triangles 21*4 = 84

Answer:
130.68 mm²
Step-by-step explanation:
given 2 similar figures with ratio of sides = a : b , then
ratio of areas = a² : b²
here ratio of sides = 5 : 11 , then
ratio of areas = 5² : 11² = 25 : 121
let x be the area of Δ YPR , then by proportion
[tex]\frac{25}{27}[/tex] = [tex]\frac{121}{x}[/tex] ( cross- multiply )
25x = 3267 ( divide both sides by 25 )
x = 130.68
area of Δ YPR ≈ 130.68 mm²
A bat flies 180 feet in 20 seconds. At this rate, how far can it fly in 30 seconds?
Answer:
270
Step-by-step explanation:
To solve this, we use the unitary method.
Distance flown in 20 sec = 180
Distance flown in one sec = [tex]\frac{180}{20}[/tex] = 9
Thus, distance flow in 30 secs = 9 × 30 = 270
I think this is the answer. Hope its correct :)

Answer:
m = -1/2, y-intercept = -3, x-intercept = -6,0
Step-by-step explanation:
M is the gradient (or slope) and is always in front of the x coefficient. -1/2 in this case.
To find the y-intercept, we have to know that it is at the point where the graph passes through the y-axis. At this point x = 0. So just substitute 0 for x and solve for y to give -3.
To find the x-intercept, do the opposite. When the graph passes through the x-axis, y = 0. So when y = 0, x = -6

What is the measure of angle x?
Answer:
83 is the measure of x.
Step-by-step explanation:
A triangle is equal to 180 degrees. So 180 - 53 - 44 = 83.
Answer:
83 degrees
Step-by-step explanation:
The measure of all three angles in any triangle will always add up to 180.
To solve a problem like this, simply add up the given measurements and then subtract that total from 180. In this case you would get an answer of 180 degrees.

What is geometric series diverges?Geometric sequence is the sequence in which the next term is obtained by multiplying the previous term with the same number for the whole series.
It can be given as,
[tex]a+ar+ ar^2+ ar^3+...[/tex]
Here,
is the (a) first term of the sequence, and (r) is the common ratio.
To be a series as geometric series diverges, it should follow,
[tex]|r| > 1[/tex]
First option given as,
3/5+3/10+3/20+3/40+ ...
Here, the common ratio is,
[tex]r=\dfrac{\dfrac{3}{10}}{\dfrac{3}{5}}\\r=\dfrac{1}{2}[/tex]
The common ratio is less than one. Thus option a is not correct.
First option given as,

Here, the common ratio is,
[tex]r=\dfrac{4}{-10}\\r=\dfrac{-2}{5}[/tex]
For the option number two the common ratio is (-2/5) which is less than 1. This option is also not correct.
In the option number c, the value of common ratio is -4. The absolute value of common ratio is,
[tex]|r|=|-4|\\|r|=4[/tex]
The absolute value of this common ratio is more than one. Thus, this is the correct option.

A computer company claims that the lifespan of its batteries is 2. 7 years. The population standard deviation is 0. 85 years. A sample of 25 batteries was tested, and their mean lifespan was 3. 1 years. Using a 95% confidence level, determine if the company's claim is correct. Reject the null hypothesis. There is enough evidence to oppose the company's claim. Fail to reject the null hypothesis. There is enough evidence to oppose the company's claim. Reject the null hypothesis. There is not enough evidence to oppose the company's claim. Fail to reject the null hypothesis. There is not enough evidence to oppose the company's claim
Using the z-distribution, as we have the standard deviation for the population, it is found that the correct decision is given by:
Reject the null hypothesis. There is enough evidence to oppose the company's claim.
What are the hypothesis tested?At the null hypothesis, it is tested if the mean is of 2.7 years, that is:
[tex]H_0: \mu = 2.7[/tex]
At the alternative hypothesis, it is tested if the mean is different of 2.7 years, hence:
[tex]H_1: \mu \neq 2.7[/tex]
What is the test statistic?The test statistic is given by:
[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.[tex]\sigma[/tex] is the standard deviation of the sample.n is the sample size.In this problem, the values of the parameters are given by:
[tex]\overline{x} = 3.1, \mu = 2.7, \sigma = 0.85, n = 25[/tex]
Hence, the value of the test statistic is given by:
[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{3.1 - 2.7}{\frac{0.85}{\sqrt{25}}}[/tex]
[tex]z = 2.35[/tex]
What is the decision?Considering a two-tailed test, as we are testing if the mean is different of a value, with a significance level of 0.05, the critical value is of [tex]|z^{\ast}| = 1.96[/tex].
Since the absolute value of the test statistic is greater than the critical value, the correct decision is:
Reject the null hypothesis. There is enough evidence to oppose the company's claim.
More can be learned about the z-distribution at https://brainly.com/question/16313918
Answer:
Reject the null hypothesis. There is enough evidence to oppose the company's claim.
Step-by-step explanation:
The test statistic needs to fall within the rejection regions that are above and below the critical z-score associated with a 5% level of significance in order to reject the null hypothesis. Otherwise, we will fail to reject the null hypothesis.
