James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements ar

GarryVolchara [31]

Answer:

When x=2, both expressions have a value of 18.

The expressions have equivalent values for any value of x.

The expressions have equivalent values if x=8

Step-by-step explanation:

James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply. 7 x + 4 and 3 x + 5 + 4 x minus 1

When x = 2, both expressions have a value of 18.

7x + 4

= 7(2) + 4

= 14 + 4

= 18

3x + 5 + 4x - 1

3(2) + 5 + 4(2) - 1

6 + 5 + 8 - 1

= 18

The expressions are only equivalent for x = 4 and x = 6.

• This is not true because the expression is also equivalent for x = 2

The expressions are only equivalent when evaluated with even values.

When x = 1

7x + 4

7(1) + 4

= 7 + 4

= 11

3x + 5 + 4x - 1

3(1) + 5 + 4(1) - 1

3 + 5 + 4 - 1

= 11

The expressions have equivalent values for any value of x.

Yes, it has an equivalent value at any value of x

The expressions should have been evaluated with one odd value and one even value.

When x = 0, the first expression has a value of 4 and the second expression has a value of 5.

7x + 4

7(0) + 4

= 0 + 4

= 4

3x + 5 + 4x - 1

3(0) + 5 + 4(0) - 1

0 + 5 + 0 -1

= 4

The expressions have equivalent values if x = 8.

7x + 4

7(8) + 4

56 + 4

= 60

3x + 5 + 4x - 1

3(8) + 5 + 4(8) - 1

24 + 5 + 32 - 1

= 60

The yield from silver queen was compared to the yield of country gentlemen. Note: Differences were taken by taking Silver Queen

Mumz [18]

Answer:

$-0.223 \leq \mu_{sylver} -\mu_{Country} \leq 0.988$

We can conclude that the difference between the two means are between -0.223 and 0.988.

And for this case the confidence interval contains the value of 0 so then we have enough evidence to conclude that we don't have significant difference between the means of Silver Queen and the Country Gentlemen.

Step-by-step explanation:

For this case we have the following interval for the difference between Silver Queen - Country Gentlemen:

$-0.223 \leq \mu_{sylver} -\mu_{Country} \leq 0.988$

We can conclude that the difference between the two means are between -0.223 and 0.988.

And for this case the confidence interval contains the value of 0 so then we have enough evidence to conclude that we don't have significant difference between the means of Silver Queen and the Country Gentlemen.

Paha777 [63]

The answer is
60 km/h

Explanation:
To find the average speed, we have to divide the distance by the time taken. So,
avg. speed= distance/time
(600/10)km/h=60km/h
