The number of frogs on the pond is Proportional to the number of salamanders placed in the pond. Suppose there are 10 Frog’s for

bonufazy [111]

Answer:

Y=10x

(multiply 10 times the salamanders)

Step-by-step explanation:

a formula that can be used for this circumstance is a linear y=mx+b problem. for 1 salamander there are 10 frogs. so with this we can state that y=10x. whatever you plug into the x for the number of salamanders will give you the answer of how many frogs are in the pond. for example.

Y=10x

Y=10(3)

Y=30

30 frogs.

also because 10 is a nice number you can just multiply the number of salamanders times 10. 3*10=30

4d. Health Survey. In a survey of 1020 adults in the United States, 44% said that they wash their hands after riding public tran

AleksandrR [38]

Answer:

Discrete. See explanation below

Step-by-step explanation:

We need to remember some previous concepts:

We have two types of numerical data: Discrete and Continuous

When we say Discrete data we are refering to data that is countable or can be expressed with integers in a domain.

In the other case when we talk about continuous data we are refering to data that is continuous in a specified domain, it can contain decimals or rational numbers in the Real numbers for example.

For this special case we know that they select a sample size of n=1020 and the sample proportion of people in the United States who wash their hands after riding public transportation was 0.44 or 44% in percentage.

$\hat p = \frac{X}{1020}=0.44$

$X=0.44*1020=448.8 \approx 449$

But the number of subjects on this survey needs to be Discrete, since the possible values are 0,1,2,3,4,.....,n and never we have decimals or continuous data in order to express this.

Can someone help me do this

SCORPION-xisa [38]

Answer:

6

Step-by-step explanation:

Find the missing angle:

180⁰ - 82⁰ = 98⁰

Find the sum of the angles given without the missing angle:

180⁰ - 98⁰ = 82⁰

The sum of both the angles is 82⁰

Write an equation:

5x + 8 + 6x + 8 = 82⁰

Collect the like terms together

11x + 16⁰ = 82⁰

Subtract 16⁰ from both sides

11x = 66⁰

Divide by 11 on both sides

x = 6⁰

Answer:

m = 3

n = 14

p = 2

Step-by-step explanation:

Given:

$\frac{7}{x}-\frac{3}{2}=\frac{n-mx}{px}$

We need to find the values of m, n, p

Solution:

We will first solve the L.H.S

L.H.S = $\frac{7}{x}-\frac{3}{2}$

Now we will first make the denominator common by taking L.C.M

$=\frac{7\times 2}{x\times 2}-\frac{3\timesx}{2\timesx}\\\\= \frac{14}{2x}-\frac{3x}{2x}$

Now the denominator is common hence we will subtract the numerators.

L.H.S $= \frac{14-3x}{2x}$

Now Comparing the the value of L.H.S with R.H.S we can say that;

$\frac{14-3x}{2x}=\frac{n-mx}{px}$

m = 3

n = 14

p = 2
