The mean temperature for the first 4 days in January was -4°C. The mean temperature for the first 5 days in January was -6°C. What was the temperature on the 5th day? Pls help

Answers

Answer 1

Answer:

-14°C

Step-by-step explanation:

Given that,

The mean temperature for the first 4 days in January was -4°C.

The mean temperature for the first 5 days in January was -6°C.

Mean = sum of observations/no. of observations

For first 4 days,

[tex]-4=\dfrac{S_4}{4}\\\\S_4=-16\ ...(1)[/tex]

For first 5 days,

[tex]-6=\dfrac{S_4+T}{5}\\\\S_4+T=-30\ ..(2)[/tex]

Let the temperature on 5th day is T. So,

Put S₄ = -16 in equation (2).

-16 + T = -30

T = -30+16

T = -14°C

So, the temperature on the 5th day is -14°C.

Answers

Answer:

774.25

Step-by-step explanation:

8.75 becomes .0875 because it is 8.75%/100%

711.95 x .0875 = 62.295625

add the cost (711.95) and the tax (62.295625)

711.95 + 62.295625 = 774.245625

Answer:

The interest is $1242.734 and the amount is $13242.734.

Step-by-step explanation:

STEP 1: Convert interest rate of 1.5% per month into rate per year.

STEP 2: Convert 210 days into years.

STEP 3: Find an interest by using the formula , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.

In this example P = $12000, i = 18% and t = 0.57534 years, so

STEP 4: Find an amount by using the formula .

Since P = $12000 and I = $1242.734 we have

how do we add fractions

Answers

find the common denominator between the two fractions and change the numerator

Answer:

you have to find a common denominator and then add.

Step-by-step explanation:

for example 2/4 + 4/12

you find the common denominator in this case it would be i will use 4 so 2/4 would stay the same and 4/12 would change to 1/3

*make sure to do the same thing to the numerator to so if you are dividing your denominator by 2 also do the numerator

now you have to add

2/4 + 4/12 = 6/12 (the denominator stays the same)

6/12 can be simplified (if you are asked to simplify) so it is 1/6

The measure of angle ABD is (0.15x+65) and the measure of angle CBD is(0.1x+28) . Find the value of x.

Answers

Answer:

x = 348

Step-by-step explanation:

The measure of angle ABD is (0.15x+65) and the measure of angle CBD is(0.1x+28) . Find the value of x.

0.15x + 65 + 0.1x + 28 = 180

0.25x + 93 = 180

0.25x = 180 - 93

0.25x = 87

x = 87/0.25

x = 348

Find the value of x.

Answers

Answer:

50

Step-by-step explanation:

The upper left hand arc is also 130

The lower right hand arc is also x

A circle all the way around from some starting point is 360 degrees.

x + x + 130 + 130 = 360            Equation. Combine like terms.

2x + 260 = 360                         Subtract 260 from both sides

2x = 360 - 260                    

2x = 100                                    Divide by 2

x = 100/2

x = 50
