Step-by-step explanation:

Since c is on the left of -1 on the number line,

c < -1.

If we add 2 to both sides of the inequality we get c + 2 < 1.

Hence the correct sign is "<".

Answer:

30.8, 37

Step-by-step explanation:

First, we know that the angles in a triangle add up to 180, so 180-75-48= m∠G=57°. Then, using sohcahtoa, we have tan(G) = DF/FG = DF/20. tan(G) ≈ 1.54, so 20(1.54)=DF≈ 30.8

Next, using sohcahtoa, we have cos(G) = FG/DG = 20/DG. cos(G)≈0.54, and 20/0.54=DG ≈ 37

Answer:

13- 25 fish

14- 9 miles

15- 7.825 ft3

16- 11.3 feet

Step-by-step explanation:

13-

        14 x 2 = 28 fish

        He dropped three things so:

        28 - 3 = 25 fish

14-

         7 days x 3weeks = 21 days

         3laps x 21 days = 63 laps

         63 laps x 1/7 mile = 9 miles

15-

         all his savings: 2.6 + 7.34 + 5.71 = 15,65 ft3    

         melted snow = 15.65 / 2 = 7.825 ft3

16-

         3.5 - 1.8 = 1.7 feet

         1.7 + 9.6 = 11.3 feet

Answer:

Step-by-step explanation:

# 13.

I assume there will be no bonus, because penguin dropped some things.

14 × 2 - 3 × 1 = 25 fish

# 14.

3 laps, [tex]\frac{1}{7}[/tex] mile, 7 days, 3 weeks

3 × [tex]\frac{1}{7}[/tex] × 7 × 3 = 9 miles

Answer:

[tex]y +2 =-6(x - 1)[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (1,-2)[/tex]

[tex]m=-6[/tex]

Required

Determine the point slope equation

This can be determined using the following formula:

[tex]y - y_1 =m(x - x_1)[/tex]

Where:

[tex](x_1,y_1) = (1,-2)[/tex]

[tex]m=-6[/tex]

So, we have:

[tex]y - (-2) =-6(x - 1)[/tex]

This gives:

[tex]y +2 =-6(x - 1)[/tex]

Hence, the point slope form is [tex]y +2 =-6(x - 1)[/tex]

C. [tex]4\cdot (-6) +4 = 2\cdot (r-3)[/tex]: Number of equations: 1/Number of variables: 1 [tex]\{r\}[/tex]

D. [tex]2\cdot (-4) = 5\cdot (r-3) +3[/tex]: Number of equations: 1/Number of variables: 1 [tex]\{r\}[/tex]

E. [tex](20-1) +3\cdot r = 5\cdot (r-2) + 3[/tex]: Number of equations: 1/Number of variables: 1 [tex]\{r\}[/tex]

The linear equations which have one solution are C. [tex]4\cdot (-6) +4 = 2\cdot (r-3)[/tex], D. [tex]2\cdot (-4) = 5\cdot (r-3) +3[/tex] and E. [tex](20-1) +3\cdot r = 5\cdot (r-2) + 3[/tex].

Assumptions before conduction hypothesis test are mentioned below in the explanation.

Step-by-step explanation:

As this question is incomplete, and I will try my best to answer this question.

We are asked in this question to write the assumptions that  we check before conducting the hypothesis test.

Solution:

Assumptions of hypothesis test:

1. We have to make assumption that all the observations are independent.

2. Secondly, we need to take assumption that, all the parent population of the data reflects normal distribution.

3. Furthermore, we need to assume that experimental error or random error is independently identical and normally distributed with mean "0" and variance of (σ^2).

Above are the assumptions that we should check before conducting hypothesis test.

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + \frac{R}{n} )^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

The amount Liam got on his 18th birthday is $34,251.05.

It is the interest we earned on the interest.

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + \frac{R}{n} )^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

Example:

P = 200

R = 2%

t = 3 years

compounded annually, n =1

A = $212.24

We have,

Principal = $20,000

Rate = 3%

There are 4 quarters in a year.

It is compounded quarterly.

This means,

n = 4

t = 18 years

The amount compounded quarterly.

A = 20,000 [tex](1 + 0.0075)^{72}[/tex]

A = 20,000 x [tex]1.0075^{72}[/tex]

A = $34,251.05

Thus,

The amount Liam got on his 18th birthday is $34,251.05.

Answer:

More than 6.21 times

Step-by-step explanation:

The common ratio [tex]r=\dfrac{4}{5}[/tex]

Distance of first bounce

[tex]a_1=4\times \dfrac{4}{5}=\dfrac{16}{5}[/tex]

Second bounce

[tex]a_2=ar^{n-1}=\dfrac{16}{5}(\dfrac{4}{5})^{2-1}\\\Rightarrow a_2=\dfrac{16}{5}(\dfrac{4}{5})[/tex]

n bounce

[tex]a_n=ar^{n-1}\\\Rightarrow a_n=\dfrac{16}{5}(\dfrac{4}{5})^{n-1}[/tex]

Now the nth bounce will be less than 1 feet

[tex]\dfrac{16}{5}(\dfrac{4}{5})^{n-1}<1\\\Rightarrow (\dfrac{4}{5})^{n-1}<\dfrac{5}{16}[/tex]

Applying logarithms on both sides we get

[tex](n-1)\ln \dfrac{4}{5}<\ln\dfrac{5}{16}\\\Rightarrow n>\dfrac{\ln\dfrac{5}{16}}{\ln \dfrac{4}{5}}+1[/tex]

The inequality changes as both [tex]\ln\dfrac{5}{16}[/tex] and [tex]\ln \dfrac{4}{5}[/tex] are negative numbers.

So,

[tex]n>6.21[/tex]

Hence, the number of bounces is more than 6.21 times.

Answer: I think 53.1

Step-by-step explanation:

The object's temperature after 18.0 minutes is 425.83.

Given that,

An object's temperature cools exponentially after it is removed from a furnace (hot oven).

If its initial temperature is 730°C and it cools at a rate of 2.95% per minute.

We have to determine,

The object's temperature after 18.0 minutes.

According to the question,

The initial temperature is 730°C and it cools at a rate of 2.95% per minute,

The temperature after t minutes is modeled by an exponential function, which has the following format is,

[tex]T(t) = T(0) . (1-r)^t[/tex]

Where T(0) is the initial temperature, and r is the cooling rate, as a decimal.

Then,

T(0) = 730°c and r = 2.95% = 0.0295

Substitute all the values in the equation,

[tex]T(t) = T(0) . (1-r)^t\\\\T(18) = 730 \times (1-0.0295)^{18}[/tex]

Therefore,

The object's temperature after 18.0 minutes is,

[tex]T(t) = T(0) . (1-r)^t\\\\T(18) = 730 \times (1-0.0295)^{18}\\\\ T(18) = 730 \times 0.5833\\\\T (18) = 425.83[/tex]

Hence, The required value of the object's temperature after 18.0 minutes is 425.83.

[tex]=\binom{12}{4}=\frac{12\times 11 \times 10 \times 9}{1\times 2 \times 3\times 4}=495[/tex]

The total number of possible groups of 4 workers in which 2 persons (Hugo and Viviana) always come together
