The point F as described in the task content is at point; 0.6 on the number line.
Where does point F lie on the number line?Since it follows from.tge task content that; point D is at -3, and point E Is at 6, it follows that the length of segment, DE is; |-3-6| = 9.
Consequently, since the ratio of Df to FE ls 2:3
It follows that point F is at -3 + (2/5) × 9.

Given that the distance and angle of elevation of the tree from P are 50 m. and 32°, and Q is 100 m. from P, we have;
a. The height of the tree is approximately 31.2 m.
b. i. The distance of Q from the base of the tree is 50•√5 m.
ii. The angle of elevation of the top of the tree from Q is approximately 15.6°
iii. The bearing of the tree from Q is 296.565°
How can the distances and bearing of the tree from Q be found?a. tan(32°) = Height/50
Height = 50 × tan(32°) = 31.243 m.
Height of the tree ≈ 31.2 m.b. i. The distance, d, of Q from the base of the tree is given by Pythagorean theorem as follows;
d = √(100² + 50²) = 50•√5
The distance of Q from the base of the tree, d = 50•√5 m.ii. The angle of elevation is given by trigonometric ratios as follows;
[tex]tan (\theta) = \frac{31.243}{50 \cdot \sqrt{5} } [/tex]
Which gives;
[tex]\theta= arctan \left( \frac{31.243}{50 \cdot \sqrt{5} } \right) \approx 15.6 ^{ \circ} [/tex]
The angle of elevation of the top of the tree from Q ≈ 15.6°iii. The angle formed at Q by the lines from Q to the point P and Q to the tree is found as follows;
Angle = arctan(50/100) ≈ 26.565°
The angle between the direction north of Q and a line from Q to the tree is therefore;
90° - 26.565° = 63.435°
The bearing, which is the angle described clockwise from the direction north of Q and the direction from Q to the tree, is therefore;
Bearing = 360° - 63.435° = 296.565°
The bearing of the tree from Q = 296.565°Learn more about bearings in mathematics here:

There are 400 beads in a box. 20% of them are red, 35% of them are yellow and the rest are green. How many green beads are there in the box
Step-by-step explanation:
400 is the whole = 100%
20% (= 20 out of 100 equal parts of 100%) are red.
how many are that ?
well, again, 400 = 100%
1% = 100%/100 = 400/100 = 4
20% = 20×1% = 20×4 = 80
when you combine these 2 steps, you see you get 20% by multiplying the 100% by 20/100 or 0.20.
400 × 0.2 = 80
now,
35% are yellow.
35% = 35×1% = 35×4 = 140
or
400×0.35 = 140
red + yellow = 80 + 140 = 220
the rest are green
400 - 220 = 180
we would get this also by seeing that
red + yellow = 20% + 35% = 55%.
so, green has then the remaining 100-55 = 45%
and again
45% = 45×1% = 45×4 = 180
or
400×0.45 = 180

ANOVAthe general linear modelWhat is ANOVA?A statistical test called an analysis of variance, or ANOVA, is used to compare the means of more than two groups.
One independent variable is used in a one-way ANOVA, while two independent variables are used in a two-way ANOVA.A statistical technique called analysis of variance, or ANOVA, divides observed variance data into various components for use in further testing. When there are three or more data groups, a one-way ANOVA is used to find out how the dependent and independent variables are related.What is general linear model?A helpful framework for analysing how various variables affect various continuous variables is the general linear model (GLM).
GLM generalises the ANOVA's linear model by enabling any other kind of resual distribution id(and optimises the likelihood function, which only allows a t-test based on an estimated error of the coefficients). An GLM is therefore an ANOVA, but a GLM is not exclusively a GLM.To know more about ANOVA, here

Write an equation of the line that passes through (-1,3) and has a slope of 2.
Answer: y = -2x + 1.
Step-by-step explanation:
From (-1, 3) follow the line to go 1 to the right and 2 down (because the slope is -2). That takes you to (0, 1). So the y-intercept is 1 and the equation is y = -2x + 1.

A sweatshirt costs $48 at Hollister. The sales tax rate is 7%. How much will it cost to buy the sweatshirt?
Answer:

Step-by-step explanation:
To find the sales tax multiply the tax rate by the cost of the product and then add to the cost.
Sales tax = tax rate * cost price
= 7% * 48
= 0.07 * 48
= $ 3.36
Cost price = cost of product + sales tax

Answer:

Step-by-step explanation:
1. We know that each steel part has a volume of 1015 cubic centimeters, and the machinist wants to make 500 of these. Then the total volume of the steel part the machinist will make will be 1015 x 500.
--> 1015 x 500
--> 507500 cubic centimeters.
2. The density of the steel part is 7.95 grams per one cubic centimeter. Then the total density of the 500 steel parts will be 507500 x 7.95.
--> 507500 x 7.95
--> 4,034,625 grams.
3. For every kilo of steel part, the cost is $0.29. We should first change the 4,034,625 gram to kilo. Since 1000 grams is a kilo, we divide 4,034,625 by 1000.
--> 4,034,625 grams / 1000 = 4034.625 kilograms.
Now we multiply 4034.625 by 0.29 to find the total cost.
--> 4034.625 x 0.29
--> 1170.04125.
Since the question specifically asked to round it to the nearest dollar, our final answer becomes $1170.

Given that are two lines intersecting at a point making 4 angles, 118°, C, D and B.
B and D are opposite to each other and C and 118° are opposite to each other.
We need to find the measurement of angle C.
To find the measurement of angle C, we can use the concept of vertical angles.
Vertical angles are a pair of non-adjacent angles formed when two lines intersect.
They are always congruent, meaning they have the same measure.
In this case, angle 118° and angle C are vertical angles. So, their measures are equal:
