now, with that template in mind, let's see

$\bf \begin{array}{lllll}
y=&-1sin(&1x&-1)&+0\\
&A&B&C&D

\\\\\\
\textit{horizontal shift of }\cfrac{C}{B}\implies \cfrac{-1}{1}\implies -1
\\\\\\
\textit{A is negative, so is flipped upside-down}$

Solve for x: −2x + 5 < 7<br> a. x > −1<br> b. x < −1<br> c. x > −6<br> d. x < −6

skad [1K]

Since we divided by a negative 2 on both sides the sign switches and the answer is { a. x > -1 }

Write 7/12 as a percentage correct to two decimal places

inna [77]

58.33%. 7 divided by 12 equals 0.5833, so you can just move the decimal two places to the right to find the percentage.

Which group had the highest percentage of students like Sport.

Vesnalui [34]

The group that had the highest percentage of students that like Sports is group B.

The group that had the less percentage of students that like English is group A.

the percentage of students like Math in group A is 30% and 10% in group B

<h3>What are the percentages?</h3>

A pie chart is a graph that displays information in a circle. The circle is divided into slices which represent a numerical proportion. The sum of angles in a pie chart is 360 degrees

Percentage of students that like sports in:

Group A = [20 / (20 + 15 + 5 + 10)] x 100 = 40%
Group B = [22 / (5 + 4 + 9 + 22)] x 100 = 55%

Percentage of students that like English in:

Group A = [5 / (20 + 15 + 5 + 10)] x 100 = 10%
Group B = [5 / (5 + 4 + 9 + 22)] x 100 = 22.5%

Percentage of students that like Maths in:

Group A = [15 / (20 + 15 + 5 + 10)] x 100 = 30%

Group B = [4 / (5 + 4 + 9 + 22)] x 100 = 10%
