Answer:
M=916 2/3
Step-by-step explanation:
3250-m=1500+2(m-500)
3250-M=1500+2m-1000
3250-M=2M+500
3M=2750
M=916 2/3
Answer:
M = 1250
Step-by-step explanation:
3250 - M = 1500 + 2(M - 500)
3250 - M = 1500 + 2m - 1000
3250 - M = 500 + 2m
- 3250 -3250
- M = -2750 + 2m
-2m -2m
-3m = -2750
-3m/-3m = -2750/-3m
M = 1250

Step-by-step explanation:
Is the order pair (3,-4) a solution of the system of linear equations x+y=1 and -6x-3y=-3
↝ A single coordinate point must make both equations true in order for the point to be a solution.
Substitute x = 3 and y = -4 in both equations.
[tex]3-4=1\\-1=1[/tex]
The equation isn't true. Therefore, this isn't the solution for the system.
[tex]-6(3)-3(-4)=-3\\-18+12=-3\\-6=-3[/tex]
The equation isn't true for this one.
Conclusion ↝ The (3,-4) isn't the solution.

Answer:
X= -1.333333333 and so on.
Step-by-step explanation:
3X^2 is 9X
So 9X= -12
Divide both sides by 9 to create 0 pairs
Answer is X= -1.3333333333

3. Find the rate of change in the represented table.
Explanation:
Pick two columns from the table to form the (x,y) points.
I'll pick the last two columns, since everything is positive here. So we have the points (2, 17) and (4, 45)
Apply the slope formula to those points
m = (y2 - y1)/(x2 - x1)
m = (45 - 17)/(4 - 2)
m = (28)/(2)
m = 14
The rate of change is 14.

How long will it take for $6400 to grow to $43,800 at an interest rate of 3.4% if the interest is compounded continuously?
Round the number of years to the nearest hundredth.
Answer:
57.53years to the nearest hundredth
Step-by-step explanation:
For compound interest,A=P(1+r/100)^t
where r=rate of interest
t= investment tenor
$43800=6400(1+3.4/100)^t
which simplifies to 57.5250≈57.53 to the nearest hundredth
The sales tax rate in New Mexico is $5.125%.
A pair of pants in New Mexico costs $30 before tax.
Answer:
The tax is $1.54 and the price after tax is $31.54
Step-by-step explanation:
Percentages
The procedure to add a percentage ratio p to a given quantity q is:
* Calculate the increase as i = p*q/100
* Add the increase to the original quantity to get the final quantity f=q + i
It's given the sales tax rate in New Mexico is p=5.125%. A pair of pants in New Mexico costs q=$30 before tax.
* The increase (tax) is i = (5.125*30)/100 = $1.54
* The price after tax is f = $30 + $1.54 = $31.54
The tax is $1.54 and the price after tax is $31.54
Since an instant replay system for tennis was introduced at a major tournament, men challenged 1425 referee calls with the results that 412 of the calls were overturned. Women challenged 739 referee calls, and 221 of the calls were overturned. Use a 0.05 significance level to test the claim that men and women have equal success in challenging calls. Test the claim using a hypothesis test. Consider the first sample to be the sample of male tennis players who challenge referee calls and the second sample to be the sample of female tennis players that challenged referee calls. What are the null and alternative hypotheses for the hypothesis test.
Answer:
CI = (-0.0445, 0.0225)
there is no sufficient evidence to men and women have equal success in challenging calls
Step-by-step explanation:
Sample size for men; n1 = 1425
Number of success for men; x1 = 412
Sample size for women; n2 = 739
Number of success for women; x2 = 221
Significance level; α = 0.05
Sample proportion for men;
p1 = x1/n1 = 412/1425
p1 = 0.2891
Sample proportion for women;
p2 = x2/n2 = 221/739
p2 = 0.2991
From tables, z-score at significance level of 0.05 is 1.96.
Formula for margin of error is;
E = z√[(p1(1 - p1)/n1) + (p2(1 - p2)/n2)]
Plugging in the relevant values;
E = 1.96√[(0.2891(1 - 0.2891)/1425) + (0.2991(1 - 0.2991)/1425)]
E = 1.96 × 0.0170687
E = 0.0335
Coordinates of the confidence interval will be;
[(p1 - p2) - E], [(p1 - p2) + E]
[(0.2881 - 0.2991) - 0.0335], [(0.2881 - 0.2991) + 0.0335]
CI = (-0.0445, 0.0225)
This means that the confidence interval contains 0 since it's between (-0.0445 and 0.0225). Thus we can conclude that there is no sufficient evidence to men and women have equal success in challenging calls

Solve for x: 5x + 4 = 2(x - 5) *
1)-4 2/3
2)-3
3)-2.
4)-1/3
Answer:
14/-3 or -4 2/3
Step-by-step explanation:
First distribute the 2 into the parenthesis. Then Isolate the variable by subtracting 2x from both sides to get.
3x+4=-10
Next subtract 4 from both sides to get.
3x=-14
To isolate x divide by three on both sides to get.
x=-4 2/3
