Answer:

  g(x) = 4x² -x +64

Step-by-step explanation:

The integral of f(x) will be continuous. This means the value must be the same for x = 4- as for x = 4+.

For some constant c1, the integral in the region x ≤ 4 is ...

  ∫f(x)dx = (4x² -x +c1) +C = g(x) +C

The integral in the region x ≥ 4 is given as ...

  ∫f(x)dx = 31x +C

Evaluated at x=4, we must get the same value from either expression:

  4(4²) -4 +c1 +C = 31(4) +C

  60 +c1 = 124

  c1 = 64

__

In order to make the integral continuous at x=4, we must have ...

  g(x) = 4x² -x +64

It has long been reported that human body temperature follows a normal distribution with a mean of 98.6 degrees Fahrenheit. Ther
Kay [80]

Solution :

The normal body temperature of any human body is considered to be 98.6$^\circ \ F$. But there is a constant debate about the body temperature of a long held standard to the body temperature.

It is given that :

Null hypothesis and alternate hypothesis :

$H_0 : \mu = 98.6$

And $H_A : \mu > 98.6$

n is given as = 180

Test statistics = 3.64

Prove = 0.018 < α = 0.05 (let reject null hypothesis for α = 0.05 )

Therefore, their results are statistically significant and the result is unlikely due to chance alone.

Hello from MrBillDoesMath!

Answer:

The protein/calories ratios  are equivalent

Discussion:

For the first column

Protein/calories = 24/96 = 1/4

For the second column

Protein/calories = 28/112 = 1/4

So the protein/calories ratios  are equivalent

Thank you,

MrB

Find the sale price when the original price is $37.00 and the discount rate is 44%.
nexus9112 [7]
Sale price = original price - discount
discount = 44% of original price = 44% of $37 = 0.44 x 37 = $16.28

Sale price = $37 - $16.28 = $20.72
