Answer 1

Answer:

The last one

Step-by-step explanation:

[tex]x^3+1=0[/tex]

Subtract 1 from both sides

[tex]x^3+1-1=0-1[/tex]

simplify

[tex]x^3=-1[/tex]

[tex]\mathrm{For\:}x^3=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt[3]{f\left(a\right)},\:\sqrt[3]{f\left(a\right)}\frac{-1-\sqrt{3}i}{2},\:\sqrt[3]{f\left(a\right)}\frac{-1+\sqrt{3}i}{2}[/tex]

[tex]x=\sqrt[3]{-1},\:x=\sqrt[3]{-1}\frac{-1+\sqrt{3}i}{2},\:x=\sqrt[3]{-1}\frac{-1-\sqrt{3}i}{2}[/tex]

simplify

[tex]x=-1,\:x=\frac{1}{2}-i\frac{\sqrt{3}}{2},\:x=\frac{1}{2}+i\frac{\sqrt{3}}{2}[/tex]

(That's basically the last one but in a different way of writing it)

Answers

There are 6 numbers in a die.

So, theoretical probability of each no. = 1/6

P(1) = 7/42 = 1/6

P(2)= 6/42 =1/7

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

Answers

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.

Tillmon is the point guard for his basketball team. out of 63 attempts, tillmon scores 33 times.
Based on this information, what is his probability of scoring on his next shot?

A 1/2
B 10/21
C 11/21
D 3/6​

Answers

Answer:

C. 11/21

Step-by-step explanation:

Find the probability that he scores in general, by dividing 33 by 63:

33/63

Simplify this by dividing the numerator and denominator by 3:

= 11/21

So, the probability that he will score his next shot is 11/21

The correct answer is C. 11/21

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.

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).

Use the binomial expression (p+q)^n to calculate a binomial distribution with n=5 and p=0.3.(Show all steps)

Answers

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]

Comparing this to the given equation, we see ...

__

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:
