When born a baby weighed 8.5 pounds and gained 1.6 pounds per week for the first 10 weeks. which of the following functions accurately model the number of pounds,p, the baby weighs as function of the number of weeks,w, since it was born?
A. p= 8.5w+1.6 B. p=w/1.6 +8.5
C. P=1.6w + 8.5 D. P= w /8.5+1.6

Answers

Answer:

C. P = 1.6w + 8.5

Step-by-step explanation:

In y= mx + b,

8.5 is (b) because it is the starting weight. The baby's weight gain would be represented by (m), because it changes every week.

Answer:

4/6

Step-by-step explanation:

The probability of rolling a 6 is 1/6 as shown in the left section.

The probability of landing on tales is 1/2 as shown in the right section.

Becuase it is an or and not an and... you have to add them together.

1/6 + 1/2 = 1/6 + 3/6 = 4/6.

Therefore, the probability of rolling a 6 or landing on tails is 4/6.

Franco read 5/8 of a chapter of his history book in 2/5 of an hour. At this rate, how many chapters of his history book can he read in 1 hour?

Answers

Answer:

12.5/8 or 1 4.5/8 so the simplified answer could be 1 2.25/4

Step-by-step explanation:

multiply 5/8 by 2.5 becuase 2x2.5=5

so you want to get 5/5 for a full hour

5x2.5=12.5 and keep the donominator the same

then simplify so 1 4.5/8

Step-by-step explanation:

Facts:

Justin jogs 3 2/3 miles every morning

Jogs 4 6/10 miles every evening.

Miles jogged per day=?

To solve this question,add the 2 fractions.This makes sense because let's say you ran 3 miles in the morning and 2 miles in the evening, nothing more nothing less, and you wanted to find how much you ran in a day, you'd add these 2 nummbers.

3 2/3 + 4 6/10

Step 1: Add the whole numbers

3 2/3 + 4 6/10

3+4= 7

7 + 2/3 + 6/10

Step 2: Find a common denominator between 10 and 3

10x1= 10

10x2= 20

10x3= 30 (works for both 3 and 10)

7 + __ + __

30 30

Step 3: Change the neumerators

Now when adding fractions this way, you have to multiply and change the neumerator:

In the 1st fraction, the original denominator was 3. And 3x10= 30, right? So you must also multiply the neumerator by 10 so that they are equivalent to each other

2x10= 20

In fraction #2, the neumerator was 6. 6x3= 18

7 + 20 + 18

30 30

7+38/30= 7 38/30= 8 8/30 miles per day

QUSTIION 2

Facts:

Last year, the tree was 5 11/12 feet long.

This year, the tree is 7 2/3 feet long.

How many feet did it grow?

Convert to decimals and subtract:

7 2/3= 7.66667

5 11/12= 5.9166667

7.66667- 5.916667= about 1.75, which becomes 1 3/4

It grew 1 3/4 feet

A block of iron has dimensions of 1 cm x 2 cm x 5 cm and has a
mass of 799
What is its density? (V=lxwxh)

Answers

Answer:

79.9 units

Step-by-step explanation:

Hi there,

Before solving this problem, it is important to know the formula:

D = [tex]\frac{m}{v}[/tex].

D = density

m = mass

v = volume

Since we are given the mass and volume, we can simply enter these values into the formula to find the density of the block.

D = [tex]\frac{799}{10}[/tex]

D = 79.9

Therefore, the density of the block of iron is 79.9 units. I wrote units since you did not specify the unit for the mass. Hope this answer and explanation helps.

Cheers.

Answer:
The correct option is;
b. Stem and leaf plot

Step-by-step explanation:
A stem-and-leaf plot shows the data shape and the densities of the different classes in a graphical form such that the information in the data such as the data characteristics are self displayed by the data numbers arranged in the stem-and-leaf plot. The stem-and-leaf plot keeps the raw numerical data, in the form they were obtained and by their arrangement, outliers are easily spotted.

Answer:

Volume: 120

SA: 400

Step-by-step explanation:

Volume = Bh

Volume = (1/2 x b x h) h

Volume = (1/2 x 6 x 4) 10

Volume = 120

SA = 2B + Ph

SA = 2(1/2 x b x h) + (s + s + s)h

SA = 2(1/2 x 6 x 4) + (5 + 5 +6) 10

SA = (24 + 16) 10

How can we interpret probability?

Probability of an event is a measurement of how likely an event can occur as an outcome of a random experiment.

Probability ranges from 0 to 1, both inclusive. Events whose probability is closer to 0 are rarer to occur than those whose probabilities are closer to 1 (relatively).

Since it is given that:

The chance of a customer receiving a blue pen = 0.008The chance of a customer receiving a blue tote bag = 0.04

Both probabilities are too close to 0, than 1. So they both are very unlikely to occur.

Thus, it is very unlikely that a customer gets a blue tote bag, and it is very unlikely that a customer gets a blue pen (Option B).
