Answer:

what?

Step-by-step explanation:

By using changes of units, we will see that the correct option is d.

We know that the yellow onion weighs 0.59 lb

The red onion weighs 208.65 grams.

The thing we need to do, is write the first mass in grams, then we use:

1 lb = 453.59g

Then we can rewrite:

0.59 lb =  0.59* 453.59g = 267.62g

Then we can see that the red onion is heavier.

The difference in mass is:

m = 267.62g - 208.65g = 58.97g

Now we want to rewrite this in ounces, remember that:

1g = 0.035oz

Then:

58.97g = 58.97*0.035oz = 2.064 oz

Then the correct option must be d.

A, If n is an odd number, then n + 1 is an even number

Step-by-step explanation:

Any number that is odd, when taken up by the integer 1, will become an even number.

The Z score is -2 if the standardized exam, the scores are normally distributed with a mean of 21 and a standard deviation of 4.

It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.

We have:

u = 21

SD = 4

X = 13

[tex]\rm Z = \dfrac{13-21}{4}[/tex]

Z = -2

Thus, the Z score is -2 if the standardized exam, the scores are normally distributed with a mean of 21 and a standard deviation of 4.

Answer:

x= 7 y=6

Step-by-step explanation:

Step-by-step explanation:

the slope-intercept form is

y = ax + b

"a" is the slope (the slope is in all forms the factor of x). and "b" is the y-intercept (the y value when x = 0).

so the first equation is

y = -5x + b

b we get by using the point coordinates :

-22 = -5×5 + b = -25 + b

b = 3

so, the full equation is

y = -5x + 3

for the second equation we need to calculate the slope first. remember, it is the ratio "y coordinate change / x coordinate change" :

x changes by +1 (from -4 to -3).

y changes by +7 (from -2 to 5).

the slope is +7/+1 = 7/1 = 7.

the equation looks like

y = 7x + b

again, we use the coordinates of a point to get b. I picked (-4, -2) :

-2 = 7×-4 + b = -28 + b

b = 26

and the full equation is

y = 7x + 26

The feet of ribbon Rosa left when she has 15 yards of ribbon and used 8 feet of ribbon to tie gift bags, is 7 feet.

Subtraction is the resultant number which is obtained by reducing a number with another. Let a number a is subtracted with the another number b. Then the subtraction of these two number will be,

[tex]D=a- b[/tex]

Here, (a, b) are the real numbers.

Rosa has 15 yards of ribbon. She uses 8 feet of ribbon to tie gift bags. Let suppose she has left n feet of ribbon. Thus,
