i really need help with this 6th grade work due today

Answer: The correct answer is B.

Step-by-step explanation:

Answer:

He performed better in the 800 m race

Step-by-step explanation:

Obtain the standardized score for each event :

Zscore = (score - mean) / standard deviation

1000 meter :

Mean = 4.5 ; Standard deviation = 0.75 ; x = 4.1

Zscore = (4.1 - 4.5) / 0.75

Zscore = - 0.4 / 0.75 = - 0.5333

800 meter :

Mean = 3.2 ; Standard deviation = 0.4 ; x = 3

Zscore = (3 - 3.2) / 0.4

Zscore = - 0.2 / 0.4 = - 0.5

-0.5 > - 0.533

Hence, he performed better in the 800 m race

Answer:

Abby had a better performance in the 800-meter because this z-score was closer to the mean than the z-score for the 1,000-meter.

Step-by-step explanation:

did it on egde

[tex] \red{20 \: \frac{1}{4} \div 9}[/tex]

[tex] = \frac{81}{4} \div 9[/tex]

[tex] = \frac{^{9}\cancel{81}}{4} \times \frac{1}{\cancel{9}^{1} } [/tex]

[tex] = \frac{9}{4} [/tex]

[tex] \blue{ = \boxed{2 \: \frac{1}{4} }}[/tex]

Step-by-step explanation:

Answer:

B, -3/4

Step-by-step explanation:

Slope can be found by using rise over run. From point x the line drops three points making the rise -3, and it goes to the right four points making the run 4. That makes our answer -3/4.

Answer:

625

Step-by-step explanation: 5^6/5^2

multiply 5^6 and than devide your answer with 5^2

Answer:

625

Step-by-step explanation:

5^6=15625

5^2=25

15625/25=625

Hope this helps and sorry about your points ;-;

The range of milk production that 95% of the cows will fall within is option B: 4.8 gallons to 7.6 gallons.

To find the range of daily milk production that 95% of the cows will fall within, we can use the empirical rule, which states that for a normal distribution:

About 68% of the observations fall within one standard deviation of the mean.

About 95% of the observations fall within two standard deviations of the mean.

About 99.7% of the observations fall within three standard deviations of the mean.

Since we are looking for the range of milk production that 95% of the cows will fall within, we need to find the range that is within two standard deviations of the mean. That range is:

Mean ± 2SD

= 6.2 ± 20.7

= 6.2 ± 1.4

= [4.8, 7.6]

To learn more about the standard deviation;

Answer:

0.441

Step-by-step explanation:

[tex](6.3 \times 10^3) \times (7 \times 10^{-5} ) \\ \\ = 6.3 \times 7 \times 10^3\times 10^{-5} \\ \\ = 44.1 \times {10}^{3 - 5} \\ \\ = 44.1 \times {10}^{ - 2} \\ \\ = 0.441 [/tex]

Answer:

y = -7/2x+3

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b  where m is the slope and b is the y intercept

y = -7/2 x+b

Substitute the point into the equation

-4 = -7/2(2) +b

-4 = -7+b

Solving for b

-4+7 = -7+b+7

3 = b

The equation is y = -7/2x+3

16 hours-36 scarves

20 hours-45 scarves

24 hours-54 scarves

pattern: h+4 (hours)  s+9 (scarves)

Answer:

The more they seem to change the more they stay the same.

Answer:

its the first choice

Step-by-step explanation:

Answer:

y=  -3/5x +5

Step-by-step explanation:

Step one - find where the line is intercepting. In your case this is at positive 1.

Next step is to check the change of the slope - directio.  The line goes up to the positive Y access  and to the left of the negative X access.

That leads to a negative slope.

Respectavley the only posible  answer on this question is  

y=  -3/5x +5

Good luck.

Answer:

x = 5

Step-by-step explanation:

set JN and NL equal to each other...

14x – 17 = 3x + 38

11x = 55

x = 5

Answer:

x = 10

Step-by-step explanation:

Given

- (x - 3) = - 7 ( divide both sides by - 1 )

x - 3 = 7 ( add 3 to both sides )

x = 10
