Answer 1

Answer: A

Step-by-step explanation:

81 - 1 1/5x [tex]\leq[/tex] 55 The first thing you could do is convert the mixed fraction into an improper fraction.

1 1/5 to an improper fraction is -6/5

Now rewrite the inequality as,

81 - 6/5x [tex]\leq[/tex] 55 Subtract 81 from both sides

-81 -81

-6/5x [tex]\leq[/tex] -26 Multiply both sides of the inequality by 5

-6x [tex]\leq[/tex] -130 Divide both sides by -6 and the sign will me flip since your divide both sides by a negative number.

x ≥ 130/6 Convert 130/6 to a mixed fraction

x ≥ 21 2/3

x + 5y = 8
3x = 24 - 157

Answers

Answer:

x = [tex]-\frac{133}{3}[/tex], y = [tex]\frac{157}{15}[/tex]

Step-by-step explanation:

x + 5y = 8

3x = 24 - 157

3x = -133

x = [tex]-\frac{133}{3}[/tex]

x + 5y = 8

[tex]-\frac{133}{3}[/tex] + 5y = 8

5y = [tex]\frac{157}{3}[/tex]

y = [tex]\frac{157}{15}[/tex]

Answer:

Step-by-step explanation:

Leshonda had been working at her job for almost twenty years. She felt like she worked overtime more often than not (more than 50% of the time) and deserved a raise, so she randomly selected 50 paychecks (each for one week of work) and found that she had worked overtime in 32 of those weeks. Use a TI-83, TI-83 plus, or TI-84 calculator to test whether Leshonda worked overtime more often than not. Identify the p-value, rounding to three decimal places.

Answers

Answer:

Z statistic = 1.980

Pvalue = 0.024

Step-by-step explanation:

Sample size (n) = number of paychecks = 50

Number of overtime (x) = 32

Let Number of overtime = o

Claim : Overtime work is done more than 50% of the time ;

Null hypothesis:H0: o = 0.5

Alternative hypothesis : H1: o > 0.5

Using the T84 calculator :

Selecting the 1 proportion test under the Stat menu:

p0 = 50% = 0.5

x = 32 ; n = 50 ; >p0

The z test statistic value obtained is 1.980 (3 decimal places)

The P value = 0.024 (3 decimal places)

At α = 0.05 ;

P value < α ; therefore we reject the null

Hence, overtime work is done more than 50% of the time.

A person invests 4000 dollars in a bank. The bank pays 6.25% interest compounded
annually. To the nearest tenth of a year, how long must the person leave the money
in the bank until it reaches 9600 dollars?

Answers

Answer:

14.4

Step-by-step explanation:

Given that :

Principal = 4000

Interest (r) = 6.25% compounded annually

Calculate time, t, if final amount A = 9600

Using the compound interest formula :

A = P(1 + r/n)^n*t

A = final amount

n = number of times interest is applied per period

9600 = 4000(1 + 0.0625)^t

9600 = 4000(1.0625)^t

9600/4000 = 1.0625^t

2.4 = 1.0625^t

Take the log of both sides

0.3802112 = 0.0263289t

t = 0.3802112/0.0263289

t = 14.440811

t = 14.4 ( nearest tenth)

i need a graph of 10x+6y=150

Answers

Rearrange the equation to get it into slope intercept form:

10x+6y=150

6y=-10x+150

y=-5/3x+25

The slope is -5/3, the y-intercept is 25. Graph below:

Answer:

See below

Step-by-step explanation:

Given

10x + 6y = 150

To graph the line easily, find x-intercept and y-intercept and connect those points with a line, that will be a graph you need.

x-intercept is the coordinate of x when y = 0

10x + 6*0 = 15010x = 150x = 15

y-intercept is the coordinate of y when x = 0

10*0 + 6y = 1506y = 150y = 25

We have now required points:

(0, 25) and (15, 0)

Mandy's approval based on her debt - to - income ratio is;

C: Not likely, recurring debt is higher than what is allowed.

What is Debt to income ratio?

Debt to income ratio is simply the percentage of your gross monthly income that goes to paying your monthly debt payments.

Now, her annual salary is $37,580. This means that her monthly income is; 37580/12 = $3131.67

Her monthly debt servicing = $265 + $120 =$385

Using the 28/36 ratio, the maximum allowable recurring debt for someone with a monthly income of $3,200 is $256.

Since her recurring monthly debt is $385 it is more than the maximum recurrent limit and so her home loan will not be approved.
