Answer:
Let x be the number of hits Ricky has. Then x+277 is the number of hits Pedro has. Adding Ricky's and Pedro's hits give you 2685 hits. Therefore, x+(x+227)=2685 2x+227=2685 2x=2408 x=1204 x+277 1481 Therefore, Ricky has 1204 hits and Pedro has 1481 hits.
Step-by-step explanation:
The gradient of the tangent to the curve y = 5x³ + 3x² - x + 4 is 15x²+6x-1.
<h3>What is the gradient?</h3>
A differential operator is used for a function having a vector value in three dimensions to produce a vector whose three components are the partial derivatives of the function with respect to its three variables.
The given equation for the curve is;
y = 5x³ + 3x² - x + 4
The gradient of the tangent to the curve is;
Hence,the gradient of the tangent to the curve y = 5x³ + 3x² - x + 4 is 15x²+6x-1.

Answer:
x=8
Step-by-step explanation:
x^2 - 48 = 2x
x^2 - 2x - 48=0
(x+6)(x-8)=0
x+6=0 x-8=0
x= - 6 x=8
can not be negative so the answer is x=8
Answer:
what grade
Step-by-step explanation:
to know the rule
The selected statistical questions are as follows:
<em>A what is the typical amount of rainfall for the month of June in the Galapagos islands</em>
<em />
<em>D how many songs does the class usually listen to each day</em>
<em />
<em>G how long does it typically take for 2nd graders to walk a lap around the track</em>
Statistical questions are known by these two main characteristics:
- they are answered by the collection of data
- there is always variability in the data collected
This means that the data vary. They are not the same data. For example, "How old is Monday?" is not a statistical question because it has one answer.
Thus, statistical questions are not answered by a single number or answer, especially when the correct answer is just one.
