Answer:
The x-intercept is -7/5.
Step-by-step explanation:
Firstly, you must know what is intercept<em>.</em><em> </em><em>I</em><em>n</em><em>t</em><em>e</em><em>r</em><em>c</em><em>e</em><em>p</em><em>t</em> is the line where it touches the axis. When a line touches the one axis, the other axis <em>m</em><em>u</em><em>s</em><em>t</em><em> </em>be zero. So in this question, it given to us to find the x-intercept which means that y coordinate is zero. We have to let y equals to zero and solve for the value of x :
Let y = 0,
5x - y = -7
5x - 0 = -7
5x = -7
x = -7/5(improper fraction) or -1 2/5(mixed no.)
Answer:
48 ft³
Step-by-step explanation:
To find the height, you can use the slant height and the base.
Using the Pythagorean Theorem and 3 as the triangle's base,
a²+b²=c²
3²+b²=5²
9+b²=25
b²=16
b=4
The height of the pyramid is 4.
Volume formula for the pyramid is
Inserting our measurements:
Answer:
25.15 ponds is the weight of two year old baby corresponds to 10th percentile.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 29 pounds
Standard Deviation, σ = 3 pounds
We are given that the distribution of weight of two year old babies is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.10
P(X < x)
Calculation the value from standard normal z table, we have,
Thus, 25.15 ponds is the weight of two year old baby corresponds to 10th percentile.
Answer:
The possible values of x is given by and they include: -2, -3, -4, -5, -6 and so on
The greatest possible value of 7x is
Step-by-step explanation:
We are given the equation: x + 8 <= 6
Let collect the like terms:
Therefore, x <= -2 and the possible values include: -2, -3, -4, -5, -6 and so on
To find the greatest possible value of 7x is when x = -2.
