What are decimal places you better explain it throughly I am having much trouble I will give you 20 points or maybe even 100

Decimal places are the spaces present after a decimal, denoted by the . in a number. This means, if I had 1.2 the 2 is in the first decimal place. In 3.1415 , the 5 is in the 4th decimal place. It is also commonly called, in respective order, the tenths place, the hundreds place, the thousandths place, and so on. For example, in 1.432 the 4 is in the tenths place, the 3 is in the hundredths place, and the 2 is in the thousandths place.

Interior and Exterior Angles of Polygons -

ANTONII [103]

Answer:75

Step-by-step explanation:

180-64 gives you the angle not labelled which is 116 then to work out size of angle formula is 180(n-2) n being sides so 180(6-2) = 720 so 720 minus all the angles = 75 I think lol

Solution :

Assuming $\sigma_1^2=\sigma_2^2$

We have to test

$H_0:\mu_1=\mu_2$

Against $H_a: \mu_1 \neq \mu_2$

Level of significance, $\alpha = 0.05$

$s_p=\sqrt{\frac{(n_1-1)s_1^2+ (n_2-1)s_2^2}{n_1+n_2-2}}$

$s_p=\sqrt{\frac{(25-1)(425)^2+ (20-1)(415)^2}{25+20-2}}$

= 420.6107

Under $H_0$ , the t-statistics is as follows:

$t=\frac{(\overline{x_1} - \overline{x_2})}{s_p\sqrt{\frac{1}{n_1}+\frac{1}{n_2}}} \sim$ $\text{t with }(n_1+n_2-2) \ DF$

$t=\frac{(7200-7087)}{(420.6107)\sqrt{\frac{1}{25}+\frac{1}{20}}}$

= 0.90

DF = (25 + 20 - 2)

= 43

P-value of the test = 0.375

Since the p value is more than 0.05, we fail to reject our null hypothesis.

Una lancha que viaja a 10 m/s pasa por debajo de un puente 3 segundos después que ha pasado un bote que viaja a 7 m/s, ¿después

ExtremeBDS [4]

Answer:

La lancha y el bote se encontrarán a 70 metros de distancia del puente.

Step-by-step explanation:

Sea el punto debajo del puente el punto de referencia y que ambas lanchas se desplazan a velocidad a continuación, las ecuaciones cinemáticas para cada embarcación son presentadas a continuación:

Bote a 7 metros por segundo

$x_{A} = x_{o}+v_{A}\cdot t$ (Ec. 1)

Lancha a 10 metros por segundo

$x_{B} = x_{o}+v_{B}\cdot (t-3\,s)$ (Ec. 2)

Donde:

$x_{o}$ - Posición debajo del puente, medido en metros.

$x_{A}$ , $x_{B}$ - Posición final de cada embarcación, medido en metros.

$v_{A}$ , $v_{B}$ - Velocidad de cada embarcación, medida en metros por segundo.

$t$ - Tiempo, medido en segundos.

Para determinar la posición en la que ambas embarcaciones se encuentran, se debe determinar el instante en que ocurre a partir de la siguiente condición: $x_{A} = x_{B}$
