The cumulative frequency of students who earned a score of 20 or lower on the quiz is option d) 68.

<h3>What is the frequency about?</h3>

The relative cumulative frequency of students in the question is seen as those who earned a score of 20 to be 0.68 or 68 %.

From the question, The cumulative frequency of students who earned a score of 20 or lower on the quiz is:

= 4+8+15+7

=34.

Total frequency is:

= 4+8+15+7+7+3+4+2

=50.

Therefore, the relative cumulative frequency is:

= 34/50

= 0.68

= 68%

Hence, The cumulative frequency of students who earned a score of 20 or lower on the quiz is option d) 68.

Please help with this

prohojiy [21]

Answer:

Step-by-step explanation:

Recall that cos Ф = adj / hyp. If adj = 6 and hyp = 10, then by the Pythagorean Theorem, opp = 8: 6² + 8² = 10²

Then:

sin Ф = opp / hyp = 8/10 or 4/5

cos Ф is given: 6/10 or 3/5

tan Ф = opp / adj: 8/ 6 or 4/3

cot Ф = 1/sin Ф = 10/8 or 5/4

sec Ф = 1/ cosФ = 10/6 or 5/3

csc Ф = 1 / sin Ф = 10/8 or 5/4

BRAINLIEST FOR RIGHT ANSWER!!

Answer: ${\boxed{h(x+4)=\frac{9+3x}{8+x}}}$

Concept:

In a function f(x), it represents a function in terms of x or for x. Therefore, to find the values in the function, substitute values within the parenthesis to solve.

Solve:

Given information

$h(x)=\frac{-3+3x}{4+x}$

Need to find

$h(x+4)$

Substitute (x + 4) to the position of x

$h(x+4)=\frac{-3+3(x+4)}{4+(x+4)}$

Distributive property on the numerator

$h(x+4)=\frac{-3+3x+12}{4+(x+4)}$

Combine like terms

$h(x+4)=\frac{-3+12+3x}{4+4+x}$

$\boxed{h(x+4)=\frac{9+3x}{8+x}}$

Hope this helps!! :)
