What is 9+(5x10)+1-(15x2)

Answers

Answer:

30

Step-by-step explanation:

=9 + 5 x 10 + 1 + -15 x 2 = ( 5 x 10 ) + ( −15 x 2) + ( 9 +1  ) = 5 x 10 + −15 x 2 + 10

Answer:

30

Step-by-step explanation:

9+(5x10)+1-(15x2)

First, we must evaluate the numbers in the parentheses. (5x10) is 50, and (15x2) is 30. Since we have the answers to that, we can now put the expression as: 9 + (50) + 1 - (30).

9 + (50) = 59

59 + 1 = 60

60 - (30) = 30

Therefore, the answer is 30.

A manufacturer knows that their items have a normally distributed lifespan, with a mean of 8.4 years, and standard deviation of 0.6 years. The 4% of items with the shortest lifespan will last less than how many years?

Answers

Answer:

7.35 years

Step-by-step explanation:

Given that :

mean = 8.4

standard deviation = 0.6

From the negative z tables, the corresponding data for 0.04 = -1.75

So, using the z-score formula:

[tex]z = \dfrac{x - \mu}{\sigma}[/tex]

[tex]-1.75 = \dfrac{x - 8.4}{0.6}[/tex]

-1.75 × 0.6  = x - 8.4

- 1.05 = x - 8.4

x = -1.05 + 8.4

x =  7.35 years

the shortest lifespan will last less than 7.35 years

∴ the longest 4% will have lifespans longer than x = 8.4 + 1.75(0.6)

= 9.45 years

Answer:

Base: [tex]7[/tex]

Exponent: [tex]4[/tex]

Step-by-step explanation:

What is the base and the exponent of [tex]7^4[/tex]?

If you want to know the base, you will have to look at the whole number. The whole number is 7. So that means the base is 7. The number on top of the whole number(exponent) is gonna be the exponent. The number 4 is on the exponent. So in that case, the number 4 is the exponent. So the base is 7 and the exponent is 4.

Hope this helps!

Answer:

Base(7)

Exponent(4)

Step-by-step explanation:

A base is always the whole number. In this exponent, the whole number you see is 7. So that means 7 is the base number. The exponent is the small number you see on top of the whole number(base). The exponent on top of the whole number is 4. So the base number is 7 and the exponent is 4.

The perimeter of a certain rectangle is 16 times the width. The length is 12cm more than the width. Find the length of the rectangle. Show work.

Answers

Answer:

Step-by-step explanation:

width = w

length = 12 + w

 

Perimeter of rectangle = 2*length + 2*width since perimeter measures the distance around an object.

 

The perimeter of a certain rectangle is 16 times the width means 2 * (12 + w) + 2 *w = 16w

24 + 2w + 2w = 16w

24 + 4w = 16w  subtract 4w from both sides

24 = 12 w  divide both sides by 12

2 = w

 

width = 2 cm

length = 12 + 2 = 14 cm

what is the solution to this system of equations?
x-2y=15
2x + 4y=-18​

Answers

Answer:

x = 3; y = -6

Step-by-step explanation:

 x - 2y =  15

2x + 4y = -18​

Multiply both sides of the first equation by 2. Write the second equation below it, and add the two equations.

     2x - 4y = 30

(+)  2x + 4y = -18

---------------------------

     4x         = 12

4x/4 = 12/4

x = 3

Now we substitute 3 for x in the first equation and solve for y.

x - 2y = 15

3 - 2y = 15

-2y = 12

y = -6

Answer: x = 3; y = -6

Carissa counts by 5s from 32 to 62. Which number does carissa count?

Answers

Answer:

32, 37, 42, 47, 52, 57, 62.

Step-by-step explanation:

It is given that Carissa counts by 5s from 32 to 62.

It means, we have to add 5 in the number to get the next number.

Add 5 in 32.

[tex]32+5=37[/tex]

Now, add 5 in 37.

[tex]37+5=42[/tex]

Similarly, continue the process.

[tex]42+5=47[/tex]

[tex]47+5=52[/tex]

[tex]52+5=57[/tex]

[tex]57+5=62[/tex]

Therefore, the numbers counted by carissa are 32, 37, 42, 47, 52, 57, 62.

Out of 270 racers who started the marathon, 247 completed the race, 14 gave up, and 9 were disqualified. What percentage did not complete the marathon?

Answers

Answer:

8.5%

Step-by-step explanation:

Total number of racers = 270

From the question, we have two categories who did not complete the race.

a. 14 that gave up

b. 9 that were disqualified

Total number of those who didn't complete race = 14 +9 = 23

To get the percentage of this group in the marathon:

= (23/270)*100

= 0.0851 *100

= 8.5percent

Tim has 74 socks, all in pairs. He has 1 more pair of white socks than black socks. How many
individual socks of each color does he have?

black socks

white socks

Answers

Answers:

36 individual black socks

38 individual white socks

Check: 36+38 = 74 total individual socks

====================================================

Work Shown:

b = number of pairs of black socks

w = number of pairs of white socks

w = b+1 since he has 1 more pair of white socks compared to black socks

2b = number of individual black socks

2w = number of individual white socks

2b+2w = total number of individual socks

2b+2w = 74

2b+2(b+1) = 74 .... plug in w = b+1

2b+2b+2 = 74 ... distribute

4b+2 = 74

4b = 74-2 .... subtracting 2 from both sides

4b = 72

b = 72/4 ... dividing both sides by 4

b = 18 is the number of pairs of black socks he has

2b = 2*18 = 36 is the number of individual black socks he has

w = b+1 = 18+1 = 19 is the number of pairs of white socks he has

2w = 2*19 = 38 is the number of individual white socks he has

2b+2w = 36+38 = 74 individual socks overall

Step-by-step explanation:

Q= ( c+d)/2

Multiply each side by 2

2Q = ( c+d)/2 *2

2Q = ( c+d)

Subtract c from each side

2Q - c = c+d-c

2Q -c = d

Steps to solve:

Q = (c+d)/2

~Simplify

Q = 1/2c + 1/2d

~Subtract 1/2c to both sides

Q - 1/2c = 1/2d

~Divide 1/2 to both sides

d = 2q - c

Answer:

The calculated value t = 3.032 >  1.9904 at 5% level of significance

Step-by-step explanation:

Step(i):-

Given mean of the population 'μ'=75 feet

Given mean of the sample(x⁻) = 77

Given standard deviation of the sample(S) = 5.9

Given sample size 'n' =80

Step(ii):-

Test statistic

              [tex]t=\frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }[/tex]

             [tex]t=\frac{77-75}{\frac{5.9}{\sqrt{80} } }[/tex]

            t = 3.032

Degrees of freedom ν=n-1 = 80-1 =79

tabulated value = 1.9904 at 5% level of significance

The calculated value t = 3.032

Final answer:-

The calculated value t = 3.032 >  1.9904 at 5% level of significance
