Answer: 50° Fahrenheit

Step-by-step explanation:

Here, the equation that shows the temperature of x degree Celsius in Fahrenheit is,

F(x) = 32^{\circ} + 1.8\times x

Where x is a variable.

Thus, For the temperature of 10° Celsius,

x = 10° Celsius

The temperature in Fahrenheit is,

F(10^{\circ}C) = 32^{\circ} + 1.8\times 10

= 32^{\circ} + 18^{\circ}

=50^{\circ}\text{ Fahrenheit}

Thus, the increasing temperature by 10° C is equivalent to increasing temperature by 50° F.

dezoksy [38]

Answer:

69 (lol)

Step-by-step explanation:

PEMDAS

<u>parentheses</u>, exponents, <u>multiply</u>, divide, <u>add</u>, <u>subtract</u> (in that order)

(8*12)-2(\frac{60}{10} )-15\\=96-2(\frac{60}{10} )-15\\=96-2(6)-15\\=96-12+(-15)\\=96-27\\=69

Those are supplementary,

(x+8) + (3x+2) = 180

4x + 10 = 180

4x = 170

x = 170/4 = 85/2 = 42.5 degrees

x+8 = 50.5 degrees

3x+2 = 129.5 degrees

A university with a high water bill is interested in estimating the mean amount of time that students spend in the shower each d
Bas_tet [7]

Answer: (4.0845,\ 6.5755)

Step-by-step explanation:

As per given , we have

n = 11

\overline{x}=5.33\\\\ s=1.33

Since population standard deviation is missing, so we use t-test.

Critical t-value for 99% confidence :

t_{\alpha/2,\ n-1}=3.106   [using two-tailed t-value table]

Confidence interval :

\overline{x}\pm t_{\alpha/2}\dfrac{s}{\sqrt{n}}\\\\= 5.33\pm (3.1060)\dfrac{1.33}{\sqrt{11}}\\\\\approx5.33\pm1.2455\\\\=(5.33-1.2455,\ 5.33+1.2455)\\\\=(4.0845,\ 6.5755)

Hence,  99% confidence interval for the mean amount of time that students spend in the shower each day.= (4.0845,\ 6.5755)

The variables A, B, and C represent polynomials where A=x^2, B=3x+2, and C=x-3. What is AB-C^2 in simplest form?
yuradex [85]

Answer:

AB-C^2 = 3x^3 + x^2 + 9

Step-by-step explanation:

Hi

AB = (x^2)*(3x+2)= 3x^3 + 2x^2

C^2= (x-3)^2 = x^2 - 9

So

AB-C^2 = 3x^3 + 2x^2 - x^2 + 9 = 3x^3 + x^2 + 9

kelvin has 112 stamps in all. The ratio of the number of local stamps to the number of foreign stamps is 7:9. How many more fore
IgorC [24]

Kelvin has 14 more foreign stamps than local stamp.

Step-by-step explanation:

Given,

Total number of stamps = 112

Ratio of local stamps to foreign stamps = 7:9

Let,

The number of local stamps = 7x

The number of foreign stamps = 9x

7x+9x=112\\16x=112\\x=7

Therefore,

Number of local stamps = 7x = 7(7) = 49

Number of foreign stamps = 9x = 9(7) = 63

Difference = 63 - 49 = 14

Kelvin has 14 more foreign stamps than local stamp.
