Answer:
In the case of a Type I error, the null hypothesis would be wrongly rejected and the school district will conclude that the new technology is effective when it is not.
They will start to pay for the software when in fact it does not improve Algebra 1 skills.
Step-by-step explanation:
A Type I error happens when a true null hypothesis is rejected.
The probability of a Type I error is equal to the significance level, as it is the probabilty of getting an sample result with low probability but only due to chance, as the null hypothesis is in fact true.
In this scenario, the null hypothesis would represent the claim that the new technology does not make significant improvement.
In the case of a Type I error, this null hypothesis would be wrongly rejected and the school district will conclude that the new technology is effective when it is not.
They will start to pay for the software when in fact it does not improve Algebra 1 skills.
Answer:
x=3 over 8
Step-by-step explanation:
Simplify 4^2 to 16, divide both sides by 16, then simplify 6 over 16
Considerando la estatura de Fernando, la longitud de su sombra y la distancia con respecto a la lámpara, la altura de la lámpara encendida es de 7.20 metros. (Opción correcta: A)
<h3>Cómo aplicar el concepto geométrico de proporcionalidad</h3>
En la geometría Euclídea el concepto de proporcionalidad está asociado con el concepto de semejanza entre triángulos. Esta relación subyace en el hecho que si tenemos garantizado que existen un número suficiente y conocido de valores y características comunes entre los dos triángulos, entonces podemos determinar los valores faltantes.
En esta pregunta tenemos dos triángulos rectángulos que son semejantes, por ende, proporcionales. Por la definición de proporcionalidad derivamos la siguiente expresión para la altura de la lámpara:
<em>h/H = x/X</em> (1)
Donde:
- <em>h</em> - Estatura de Fernando, en metros.
- <em>H</em> - Altura de la lámpara, en metros.
- <em>x</em> - Longitud de base del triángulo menor, en metros.
- <em>X</em> - Longitud de base del triángulo mayor, en metros.
A continuación, reemplazamos las variables conocidas y determinamos la altura de la lámpara:
1.80<em>/H</em> <em>=</em> 2<em>/</em>8
<em>H =</em> 4 · (1.80 m)
<em>H =</em> 7.20 m

Answer:
As I understand it asks for (fog)(x)
We know f(x)= 2x + 2
And g(x) = x^2 + 1
It is going to be like we are putting g(x) inside the f(x).
So you are going to write g(x) wherever you see a x.
Step-by-step explanation:
f(x)= 2x + 2 <-- do you see the x there, so just wrote g(x) formula instead of x.
g(x) = x^2 + 1
So, it will look like this:
(fog)(x) = 2(x^2 + 1) + 2
You also can simplify this with multiplying by 2 in front ; 2x^2 + 2 +2 and you can add two 2s finally it will be, 2x^2 +4
Hope it was clear, let me knoq if you have any questions.
