A blueberry plant produces about 26 blueberries per day. If the farmer picked 472 blueberries, how many days did the plants prod

Arte-miy333 [17]3 years ago

Answer:

About 18 days.  

Step-by-step explanation:

The problem states that a blueberry plant produces about 26 blueberries per day.  So, our answer will be somewhat of an estimate for the amount of days the plants produced blueberries based on the number picked.  In order to solve for the number of days, we can set up equivalent ratios (fractions):

\frac{blueberries}{day}=\frac{26}{1}=\frac{472}{d} where 'd' = number of days.

We can cross-multiply and divide in order to find the amount of days:

\frac{26d}{26}=\frac{472}{26}

So, d ≈ 18 days.

For each point on the unit circle, select the angle that corresponds to it.
IgorC [24]

Answer:

A) 3π/4

B) 9π/7

C) 11π/6

Step-by-step explanation:

In the picture attached, the points are shown

Point A is between π/2 radians (90°) and π radians (180°). The only possible option is 3π/4

Point B is between π radians (180°) and 3π/2 radians (270°). The only possible option is 9π/7

Point C is between 3π/2 radians (270°) and 2π radians (360°). The only possible option is 11π/6

Saul decides to use the IQR to measure the spread of the data. Saul calculates the IQR of the data set to be 27
german

Answer:

n = 78

Step-by-step explanation:

IQR is the interquartile range of the data set.

So Saul had already arranged the data in order, that is the first step when calculating the interquartile range.

25, 30, 50, 50, 50, 50, 56, n., 250

Next, is to find the median so we could easily separate the data into quartiles.

The median of the data 25, 30, 50, 50, 50, 50, 56, n., 250 = 50

Then, arrange the data into the first quartile and the third quartile

first quartile = 25, 30, 50, 50

third quartile = 50, 56, n., 250

first quartile median = 30 + 50 = 80/2 = 40

third quartile = 56 + n /2

The interquartile range formula is the first quartile subtracted from the third quartile:

IQR = Q3 – Q1.

Since 27 is the interquartile range, n=

27 = (56 + n /2) - 40

Use 2 to multiply through to eliminate the denominator

54 = (56 + n) - 80

n = 78

Find the average rate of change of the function between the given values of x. y = 9+ 5x + 0.5x2 between x = 2 and x = 4.
svet-max [94.6K]

Answer:

The average rate of change is 8.

Step-by-step explanation:

The formula to calculate the average rate of change of a function F(x) is:

\frac{F(b)-F(a)}{b-a}

In this case, F(x) = 0.5x^{2} +5x+9

a=2 and b=4

You have to evaluate x=2 (which is a in the formula) and x=4 (which is b in the formula) in the function.

In order to obtain F(b) and F(a) you have to replace x=4 and x=2 in the given function:

F(b) = (0.5)4^{2} + 5(4) +9= 37

F(a) = (0.5)2^{2} + 5(2)+9=21

\frac{F(b)-F(a)}{b-a} = \frac{37-21}{4-2}=\frac{16}{2} = 8

The answer is 8.
