I need help with this question

Answers

part a:
this is really just intuition. you can go either way as long as you back up what you say.
either you think hunter would be faster because he starts out with a lot more money, or you think amado would be faster because he earns a lot more.

part b:
let x be the number of hours hunter works, and y the number that amado works.
they both need to earn 600 dollars.

hunter's money is modelled by 150 + 7.5x
to get 600 dollars
150 + 7.5x = 600
7.5x = 450
x = 60

amado's money is modelled by 12y
to get 600 dollars
12y = 600
y = 50

hunter would need to work 60 hours to make enough money, but amado would only need to work 50, so hunter will take longer.

then say whether this agrees with what you guessed in part a

Answer:

a.5/4

Step-by-step explanation:

y equals mx plus c, where m is the gradient(slope of line) & c is the constant

∴y equals (5/4)x-5,where 5/4 represents the "m" & -5 is the constant.

Therefore,5/4 is "m" which is the slope(gradient).

Step-by-step explanation:

We are given the base, which is 15 meters. When we increase the base, we will obtain the height, which is 8 meters. Now, let's substitute the base and the height in the formula to find the area of the triangle.

[tex]\rightarrow \dfrac{1}{2} \times 15 \times 8[/tex]

[tex]\rightarrow 15 \times 4[/tex]

[tex]\rightarrow 60 \ \text{m}^{2}[/tex]

Thus, the area of the triangle is [tex]\bold{60 \ \text{m}^{2}}[/tex].

When Jocelyn runs the 400 meter dash, her finishing times are normally distributed with a mean of 61 seconds and a standard deviation of 2 seconds. Using the empirical rule, what percentage of races will her finishing time be between 57 and 65 seconds?

Answers

Answer:

95% of races will her finishing time be between 57 and 65 seconds.

Step-by-step explanation:

Mean=61 seconds

Standard deviation =2

Empirical rule says,

68% of data covered between mean±1 standard deviation

95% of data covered between mean ±2 standard deviation

99.7% of data covered between mean ± 3 standard deviation.

I'll upload the Empirical rule curve.

Because 57 is 61-2(2) and 65 is 61+2(2), so, 95% of data covered.

So, according to Empirical rule, 95% of races will her finishing time.
