Answer:
797
Step-by-step explanation:
First, we need to find the number of pizzas sold last week by finding the sum of the pizzas sold:
307 + 224 + 161 + 191 = 883
Next, we need to find the proportion of stuffed crust and pan style pizzas sold last week by adding the number of both sold and dividing by the total number of pizzas sold:
(191+161) / 883 = 352 / 883
Now we need to multiply this proportion by 2000 to find the expected number of stuffed crust or pan style pizzas:
(352 / 883) * 2000 = 797.28 = 797
Answer: 0.2
Step-by-step explanation: Necesitamos ajustar la estimación de 0.1561 al décimo más cercano.
El número después del decimal es el número en el décimo lugar. Considere el número a un lado del lugar de las décimas y utilice el número para decidir si se reunirán o seguirán siendo el equivalente. Observe que el número a un lado del décimo lugar es mayor o equivalente a 5 o menos de 5. En el caso de que ese número sea más digno de mención o equivalente a 5, en ese punto el número se reunirá aún en la remota posibilidad de que ese número es menor de 5, en ese momento el número no se reunirá. Permanecerá igual.
Consideremos el número dado 0.1561
El número en el lugar de las décimas es 1
El número después del punto de las décimas es 5 (que es más prominente o equivalente a 5)
De esta manera, el número se reunirá en 0,2

<h3>What is the discriminant of a quadratic equation?</h3>
The value of a discriminant of a quadratic equation shows how many roots f(x) have. If the value of the discriminant is greater than 0 then the quadratic equation has real and distinct roots and if the value of the discriminant is equal to 0, then the quadratic equation has real and same roots. In case the value of the discriminant is less than zero then the quadratic equation will have no real roots.
In order to know if the quadratic equation has real roots or not, we need to find the discriminant of the given quadratic equations,
A.)
Here, a= -1, b=2 and c=-6
As the value of the discriminant is negative it will not have real roots.
B.)
Here, a= -2, b=3 and c=4
As the value of the discriminant is positive it will have real roots.
C.)
Here, a=2, b=1 and c=-6
As the value of the discriminant is positive it will have real roots.
A.)
Here, a=2, b=-1 and c=3
As the value of the discriminant is negative it will not have real roots.

Answer:
140
Step-by-step explanation:
first you take the product of 5/6 and 42/1, which is 210/6.
Then you devide that with 5, 210/6/5 = 210/30 or 210/6 . 1/5 = 70.
Next you multiply that with 2; 70 . 2 = 140.
There you go
