Answer:
[tex]4b^2 - 5b - 6 = 4b^2 -8b + 3b - 6 = 4b(b -2 )+3(b-2) = (4b+3)(b-2)[/tex]
option B
The factor form for of given expression is [tex](4b+3)(b-2)[/tex].
What is a method of factorizing?
Quadratic factorization using splitting of middle term : In this method splitting of middle term in to two factors.
What is the factor of given expression?The middle term of the given expression -5b can be split as 3b-8b.
On using this in the given expression we get,
[tex]4b^2-5b-6=4b^2+3b-8b-6[/tex]
Take common factor out from first two and last two terms,
[tex]b(4b+3)-2(4b+3)[/tex]
Take the common factor out.
[tex](4b+3)(b-2)[/tex]
Therefore, the factor form of given expression is [tex](4b+3)(b-2)[/tex].

This figure shows an oblique triangle-based pyramid.
What is the volume of the figure?
Answer: 88 cm^3
Step-by-step explanation:
= 1/2 • bh
= 1/2 • 6 • 8
= 24
= 1/3 • 24 • 11
= 88 cm^3
The volume of the oblique triangle-based pyramid, having dimensions 6 cm, 8 cm, 11 cm, and 36.2 cm, is 88 cm³.
What is volume?The capacity occupied by a three-dimensional solid shape is known as volume. It is difficult to visualize in any shape, yet it may be compared among shapes. For instance, a compass box has a larger volume than an eraser placed inside of it.
Given:
The dimension of the pyramid are 6 cm, 8 cm, 11 cm, and 36.2 cm,
Calculate the volume as shown below,
The Volume of the pyramid = 1 / 3 × Area of the triangle × height
The volume of the pyramid = 1 / 3 × 1 / 2 × 6 × 8 × 11
The volume of the pyramid = 528 / 6
The volume of the pyramid = 88
Thus, the volume of the pyramid is 88 cm³.

Determine whether the following study is an observational study or an experiment. If the study is an experiment, identify the control and treatment groups, and discuss whether single- or double-blinding is necessary. If the study is observational, state whether it is a case-control study, and if so, identify the cases and controls.

A. Experiment, the treatment group is patients that used the magnets and the control group is patients that received the placebo; double blind
B. Observational study; case control; the cases are the patients that received magnets, the controls are the patients that received placebos
C. Observational study; not case-control
D. Experiment, the treatment group is all patients and the control group is patients that received the magnets; single blind

Answer: B, C, C
Step-by-step explanation:
The type of data distribution which is shown on the graph of coin toss where, x is the number of heads is symmetric and discrete.
What is data distribution?The data distribution is a way to represent the values of a set of data or information. The distribution of data is generally represented in a particular order.
In the given graph, the data distribution is shown for the coin toss. The probability P(X) is shown on the y-axis of the graph, and the number of heads is shown on the x-axis.
There are two types of data distribution shown on the graph.
Symmetric - The data distribution shown on the graph is symmetric over x = 1.
Discrete - The data distribution shown on the graph is discrete because the values of X are distinct.
Hence, the type of data distribution which is shown on the graph of coin toss where, x is the number of heads is symmetric and discrete.
