D :)
Because the y values are the same, all we need to take into account is the difference in the length of the x values.

Answer: His temperature is 99°F

Step-by-step explanation:

Let's state what we know:

Steve's temperature was initially 102°F

Later it dropped 3°F lower

Since his temperature decreased we need to subtract 3 from 102 to see what his temperature is now

102-3=99

The Perimeter of the rectangle below is 94 units find the length of side peek you write your answer without variables

ivolga24 [154]

Answer:

DC = 21 ; BC = 26

Step-by-step explanation:

The perimeter of a rectangle is given by :

P = 2(length + width)

2x + 3

3x - 1

Perimeter, P = 94

Hence,

94 = 2(2x +3 + (3x - 1))

94 = 2(2x + 3 + 3x - 1)

94 = 2(5x + 2)

94 = 10x + 4

94 - 4 = 10x

90 = 10x

x = 90 /10

x = 9

DC = 2x + 3 = 2(9) + 3 = 18 + 3 = 21

BC = 3x - 1 = 3(9) - 1 = 27 - 1 = 26

Which of the following is equivalent to (5 /k) + ((k + 3) /(k + 5)) ?

Mars2501 [29]

$\frac{5}{k}+\frac{k+3}{k+5}=\frac{5(k+5)}{k(k+5)}+\frac{k(k+3)}{k(k+5)}=\frac{5k+25+k^2+3k}{k(k+5)}=\frac{k^2+8k+25}{k(k+5)}\\\\Answer:E$

A frequency table of grades has five classes (A, B, C, D,F) with frequencies of 4, 10, 17, 6, and respectively. Using percentage

fiasKO [112]

We have the frequencies for each of the grades. We can estimate the number of students graded by adding all those frequencies. Let's call N the total number of grades:

$\begin{gathered} N=4+10+17+6+2 \\ N=39 \end{gathered}$

We have then a total number of grades of 39.

The corresponding relative frequency for a grade is the ratio of the frequency to the total number of "samples", 39 in this case.

Then, for grade A, the relative frequency (RF) will be:

$RF_A=\frac{4}{39}\approx0.10256\approx10.26\text{ \%}$

This will be the fraction of the total grades that are A. Represented as a percentage will be 10.26%, rounded to two decimal places.

Now, to complete the table we do the same for the other frequencies:

For grade B:

$RF_B=\frac{10}{39}\approx0.2564\approx25.64\text{ \%}$

For grade C:

$RF_C=\frac{17}{39}\approx0.4359\approx43.59\text{ \%}$

For grade D:

$RF_D=\frac{6}{39}\approx0.1538\approx15.38\text{ \%}$

For grade F:

$RF_D=\frac{2}{39}\approx0.0513\approx5.13\text{ \%}$
