Answer:
C, D and F are true
Step-by-step explanation:
The DCB triangle is isosceles, so it means the angles D and B are the same and as the angle C is 90°, B and C need to be 45° (because the sum of the internal angles of a triangle is always 180°). The sin(B) = sin(C) = sqrt2/2 and the tan(B) = tan(C) = 1

Hope this helps! Have a good day!
Answer:
Pretty sure 4.1 is an even number, 88° to be exact.
since your homework is quite much and kinda boring, the only thing you could offer me as motivation are brainliests. like in reposting the same sheet.
but this here for free: the of all three angles inside a triangle is 180 degrees.
half a turn of a full circle is 180 degrees, wich is important to calculate excercises 2 and 3 using subtraction.
for the first brainliest you can have 1-4
for the second 5-7 and for the third and fourth 8-9 and 10-11.
the whole sheet for a maybe-brainliest just isn't enough. it's like half an hour of grind work man
Use the binomial expression (p+q)^n to calculate a binomial distribution with n=5 and p=0.3.(Show all steps)
Answer:
The binomial in expanded form is [tex](0.3 + q)^{5} = \frac{243}{100000} + \frac{81}{2000}\cdot q + \frac{27}{100}\cdot q^{2} + \frac{9}{10} \cdot q^{3} + \frac{3}{2}\cdot q^{4} + q^{5}[/tex].
Step-by-step explanation:
The Binomial Theorem states that a binomial of the form [tex](a + b)^{n}[/tex] can be expanded by using the following identity:
[tex](a + b)^{n} = \Sigma \limits^{n}_{k = 0}\,\frac{n!}{k!\cdot (n-k)!}\cdot a^{n-k}\cdot b^{k}[/tex] (1)
If we know that [tex]a = p = 0.3[/tex] and [tex]n = 5[/tex], then the expanded form of the binomial is:
[tex](p+q)^{n} = \frac{243}{100000} + 5\cdot \left(\frac{81}{10000} \right)\cdot q + 10\cdot \left(\frac{27}{1000})\cdot q^{2} + 10\cdot \left(\frac{9}{100} \right)\cdot q^{3} + 5\cdot \left(\frac{3}{10} \right)\cdot q^{4} + q^{5}[/tex]
[tex](0.3 + q)^{5} = \frac{243}{100000} + \frac{81}{2000}\cdot q + \frac{27}{100}\cdot q^{2} + \frac{9}{10} \cdot q^{3} + \frac{3}{2}\cdot q^{4} + q^{5}[/tex]
write the standard form of 4/9 rational numbers
Answer:
Here a rational number is in standard form if its denominator is positive in lowest term.
[tex]\frac{4}{-9} =\frac{-4}{9}[/tex]

Answer:
3x³ + x² + x + 1
= 3x³ - 3x² + 4x² - 4x + 5x - 5 + 6
= 3x²(x - 1) + 4x(x - 1) + 5(x - 1) + 6
= (x - 1)(3x² + 4x + 5) + 6
but 3x³ + x² + x + 1 = (x - 1).Q(x) + R
=> Q(x) = 3x² + 4x + 5
R = 6

Step-by-step explanation:
a2+(48)2=
502\,\,50^{2}502
Use the Pythagorean Theorem.
a2+2304=a^{2}+2304=a2+2304=
2500\,\,25002500
Simplify.
−2304-2304\phantom{=}−2304=
−2304\,\,-2304−2304
Subtract 2304 from both sides.
a2=a^{2}=a2=
196\,\,196196
a2=\sqrt{a^{2}}=a2
=
±196\,\,\pm\sqrt{196}±196
Square root both sides.
a=a=a=
14\,\,1414
Simplify. Ignore negative root, as length must be positive.

Mateo es un panadero que necesita de cajas grandes para colocar 450 alfajores y 105 empanadas (sin mezclar ambos productos), para donarlos a los más necesitados. ¿Cuántas cajas harán falta
Answer:
Se necesitan 15 cajas para almacenar cada alimento por separado.
Step-by-step explanation:
En este ejercicio necesitamos hallar el Máximo Común Divisor entre la cantidad disponible de alfajores y empanadas, cada una de las cuales se almacenan sin mezclar. Para ello descomponemos factorialmente cada número:
Cantidad de alfajores
[tex]450 = 2\times 3^{2}\times 5^{2}[/tex]
Cantidad de empanadas
[tex]105 = 3\times 5\times 7[/tex]
El Máximo Común Divisor consiste en el factor común de cada uno de los productos de números primos:
[tex]M.C.D. = 3\times 5[/tex]
Entonces, cada caja tiene una capacidad máxima de 7 empanadas o 30 alfajores y se necesitan 15 cajas para almacenar cada alimento por separado.

Answer:
∠FJG= 135
Step-by-step explanation:
∠FJG + ∠GJH = 168 so
(6x - 15) + (x + 8) = 168
7x - 7 = 168
7x = 175
x = 25
plug it in ∠FJG
6(25) - 15 = 135

The Gender Gap in STEM Fields: The Impact of the Gender Stereotype of Math and Science on Secondary Students' Career Aspirations
Elena Makarova1*, Belinda Aeschlimann2 and Walter Herzog3
1Institute for Educational Sciences, University of Basel, Basel, Switzerland
2Swiss Federal Institute for Vocational Education and Training SFIVET, Bern, Switzerland
3Institute of Educational Science, University of Bern, Bern, Switzerland
Studies have repeatedly reported that math and science are perceived as male domains, and scientists as predominantly male. However, the impact of the gender image of school science subjects on young people's career choice has not yet been analyzed. This paper investigates the impact of the masculinity image of three school subjects—chemistry, mathematics, and physics—on secondary students' career aspirations in STEM fields. The data originated from a cross-sectional study among 1'364 Swiss secondary school students who were close to obtaining their matriculation diploma. By means of a standardized survey, data on students' perception of masculinity of science school subjects were collected using semantic differentials. The results indicate that for both sexes, math has the strongest masculinity attribution, followed by physics as second, and, finally, chemistry with the lowest masculinity attribution. With respect to gender differences, our findings have shown that among female students, the attribution of masculinity to the three school subjects does not differ significantly, meaning that female students rated all subjects similarly strongly as masculine. Within the group of male students however, the attribution of masculinity to math compared to chemistry and physics differs significantly, whereas the attribution of masculinity to chemistry and physics does not. Our findings also suggest that gender-science stereotypes of math and science can potentially influence young women's and men's aspirations to enroll in a STEM major at university by showing that a less pronounced masculine image of science has the potential to increase the likelihood of STEM career aspirations. Finally, the paper discusses ways of changing the image of math and science in the context of secondary education in order to overcome the disparities between females and males in STEM.

O Linear association
O Non-Linear association
No association
Answer:
Step-by-step explanation:
I'm assuming that non-linear means that there is some type of association between the dots, they are just not in a straight line. Now, they definitely are NOT in a straight line, but they do appear to be falling in an exponential pattern. I would say that this is a non-liner association (exponential decay, to be specific).

{y = ½ x + 8 {y = mx - 6 1)What value of “m” makes the system show parallel lines? 2)Explain.
9514 1404 393
Answer:
m = 1/2 lines are parallel when the slopes are the sameStep-by-step explanation:
1) The given line is in "slope-intercept form."
y = mx + b . . . . . . . . line with slope m and y-intercept b
Comparing this to the given equation, we see ...
m = 1/2 . . . . slope of given line
__
Two lines are parallel when they have the same slope. Then the value of m that makes the second line parallel to the first is the same value of m:
m = 1/2
_____
2) Lines with the same slope are parallel, so the value of m needs to match the coefficient of x (the slope) in the given equation.

Chen is playing a game that requires each player to spin an arrow to one of four colors, equally divided: green, orange, purple, or yellow.
Four players before Chen spun the arrow to purple, but Chen really wants her arrow to land on green. How is the probability of Chen’s spin affected by the spins of previous players?
Chen's probability of landing on purple is increased because the previous players all landed on green.
Chen's chances of landing on purple are not affected by the other players landing on green.
Chen's probability of landing on purple is decreased because the previous players all landed on green.
Answer:
1/4
Step-by-step explanation:
They are equally divided and there are a total 4 sections.
To find probability for yellow:
Numerator : how many yellows sections there are
Denominator : total sections there are
Therefore, the probability would be 1 in 4 chances.

Show the relationship between the number of weeks and Mike's savings using an equation.
Type your answer starting with either "W=" or "S=".
Answer: S = 50W + 75
Step-by-step explanation:
I got to this answer by a bit of trial and error.
I first noticed that the relationship between the balance in the savings account from week to week was increasing by 50.
But when I tried W = S + 50, that did not work at all because when I plug in 125 for S, I should get 1 for W, but instead I get 175. So I realized I had something backwards.
I then tried listing the relationship as ordered pairs of (W, S).
For example I did (1, 125), (2, 175), (3, 275) and so on. So I thought of S like y and W like x where S is a function of W. I used the equation y = mx +b or S=mW + b as an outline. I figured that W would have to be multiplied by 50 to get that jump between the numbers in the S column. But I could not do S=50W + 125 because if W = 1, S = 175 when S should equal 125. So I subtracted 50 from the 125 and got 75. So my final equation was S=50W+75. If you test it with the ordered pairs listed above, you will see that the equation checks out. Try it yourself! I hope this was helpful in some way. Good luck!
