Answer:
y = -5/2x + -4 (or) y = -5/2x - 4
Step-by-step explanation:
Your slope is -5/2, so all you have to do is take the point (-2, 1) and use the slope to find a second point of (0, -4) which is coincidentally the y-intercept. Then you just plug the data into the equation y = mx+b. You do that and you get the answer of y = -5/2x+-4

What is the Gcf of 225 and 415
Answer:
5
Step-by-step explanation:
To get the Greates Common Factor (GCF) of 225 and 415 we need to factor each value first and then we choose all the copies of factors and multiply them:
225: 3 3 5 5
415: 5 83
GCF: 5
The Greates Common Factor (GCF) is: 5
Answer:
5
Step-by-step explanation:
The factors of 225 are: 1, 3, 5, 9, 15, 25, 45, 75, 225
The factors of 415 are: 1, 5, 83, 415
Then the greatest common factor is 5.

Martha Stewart has developed a new perfume. She decides to test its side effects by spraying the perfume in 31 randomly chosen houses. She records the level of antigens that create an allergic response. If the antigen level is high enough, the person will go into anaphylactic shock. The mean of her sample is a lot bigger than the median, but Martha hopes that a 90% confidence interval will contain zero. Her confidence interval is (0.116, 1.884). Disappointed, she offers you $144 to find an acceptable, realistic way to change the confidence interval to contain zero. What could you say to earn the money
The acceptable and realistic ways to to change the confidence interval to contain zero are;
Martha should decrease x-bar by providing medicine to treat shock to the perfume users.Decrease sample size than 30Increase the confidence level, till the interval contains zeroReasons:
The confidence interval is given by the following formula;
[tex]CI=\bar{x}\pm t_{\alpha/2} \cdot \dfrac{s}{\sqrt{n}}[/tex]
When the mean, [tex]\overline x[/tex], is positive and large, both values, [tex]\bar{x}+ t_{\alpha/2} \cdot \dfrac{s}{\sqrt{n}}[/tex], and [tex]\bar{x} -t_{\alpha/2} \cdot \dfrac{s}{\sqrt{n}}[/tex], will be positive.
Therefore, Martha has to either intervene to reduce the mean also known as x-bar
Increasing the confidence level will increase the allowable error such that [tex]\bar{x} < t_{\alpha/2} \cdot \dfrac{s}{\sqrt{n}}[/tex], and the interval will contain zero
Therefore;
Martha should decrease x-bar, [tex]\overline x[/tex], by providing medicine to treat shock to the perfume usersUse a much smaller sample size, n, such that [tex]t_{\alpha/2} \cdot \dfrac{s}{\sqrt{n}} > \bar{x}[/tex]Increase the confidence level to 95% or 99%, thereby increasing the error boundLearn more here:

Solve the inequality: x+10>2x/5. *
Hello BATAPAAKO!
[tex] \huge \boxed{\mathbb{QUESTION} \downarrow}[/tex]
Solve the inequality: x+10>2x/5.
[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
[tex]x + 10 \gt \frac { 2 x } { 5 } \\ [/tex]
Firstly, multiply both sides of the equation by 5.
[tex]5(x + 10) > 2x \\ = 5x + 50 > 2x[/tex]
Since 5 is greater than 0, the direction of the inequality will remain unchanged. Now, subtract 2x from both the sides.
[tex]5x + 50 > 20 \\ = 5x + 50 - 2x > 0[/tex]
Combine 5x & -2x to get 3x.
[tex]5x + 50 - 2x > 0 \\ = 5x - 2x + 50 > 0 \\ = 3x + 50 > 0[/tex]
Now, subtract 50 from both the sides. Remember :- anything subtracted by 0 will result in its negation. So 50 subtracted from 0 will give you -50.
[tex]3x + 50 > 0 \\ = 3x > - 50[/tex]
Divide both sides of the equation by 3. Again, since 3 is > 0, the direction of inequality will remain unchanged.
[tex]3x > - 50 \\ = \large\boxed{\boxed{ \bf \: x > - \frac{ 50}{3} }}[/tex]

 what is the geometric sequence and the 8th term and the 10th term
Answer:
The geometric sequence is decreasing by 0.5 * each term
common ratio = 0.5
an equation for this exact sequence would be
50(0.5)^x-1
Step-by-step explanation:
To find the common ratio for a geometric sequence we can divide the previous term value by the next term value
so 50 / 25 = 0.5
and to check we can divide
25 / 12.5 = 0.5
So our common ratio is 0.5
Step-by-step explanation:
Given sequence:
50, 25, 12.5, ...The first term is 50 and the common ratio is:
r = 12.5/25 = 25/50 = 1/2The equation:
tₙ = t₁rⁿ⁻¹tₙ = 50(1/2)ⁿ⁻¹Find the 8th and 10th terms:
t₈ = 50(1/2)⁷ = 0.390625t₁₀ = 50(1/2)⁹ = 0.09765625Four students are training for their cross country team at school. They were told to run for as long as they could without stopping.
