Answer:
He made 5 cakes
Step-by-step explanation:
49 divided by 7 = 7
56 divided by 7 = 8
70 divided by 7 = 10
63 divided by 7 = 9
So for one cake you would need 7 g sugar, 8 g butter, 10 g flour, and 9 ml milk. So, 50 divided by 10 = 5 cakes

Step-by-step explanation:
The honeybee dataset contains data collected from the USDA on the estimated number of honeybee colonies (in thousands) for the years 1995 through 2012. We use technology to find that a regression line to predict number of thousand) colonies from year (in calendar year) is:
Colonies = 19, 291,511-8.358(Year)
a. Interpret the slope of the line in context as done in the textbook.
b. Often researchers will adjust a year explanatory variable such that it represents years since the first-year data were collected. Why might they do this? (Hint: Consider interpreting the y-intercept in this regression line.)
c. Beginning with the equation and showing the steps, predict the bee population in 2100. State why or why not this prediction is appropriate.
Solution :
a). [tex]$\widehat{y} = 19291511 - 8.358 $[/tex] (year)
As one year increases, the honey bees decreases by 8.358 in thousands.
b). As the year is kept constant, at the start of the regression, the basic value of bees is 19291511 in 1995.
c). Prediction of population of homey bees in the year 2100.
x = 105
[tex]$\widehat{y} = 19291511-8.358(105)(1000)$[/tex]
= 19291511 - 877590
= 18413921
It is not an appropriate prediction as the year 2100 is out of the range of the given regression model.
If a1 = 4 and an = -3an-1 then find the value of a4.
Answer:
[tex]a_4 = -108[/tex]
Step-by-step explanation:
Given
[tex]a_n = -3a_{n-1}[/tex]
[tex]a_1 = 4[/tex]
Required
Find [tex]a_4[/tex]
[tex]a_4 = -3a_{4-1}[/tex]
[tex]a_4 = -3a_3[/tex]
We calculate for a3
[tex]a_3 = -3a_{3-1}[/tex]
[tex]a_3 = -3a_2[/tex]
Calculate for a2
[tex]a_2 = -3a_{2-1[/tex]
[tex]a_2 = -3a_1[/tex]
Substitute 4 for a1
[tex]a_2 = -3*4[/tex]
[tex]a_2 = -12[/tex]
Substitute -12 for a2 in [tex]a_3 = -3a_2[/tex]
[tex]a_3 = -3 * -12[/tex]
[tex]a_3 = 36[/tex]
Substitute 36 for a3 in [tex]a_4 = -3a_3[/tex]
[tex]a_4 = -3*36[/tex]
[tex]a_4 = -108[/tex]

Step-by-step explanation:
10. 2(x^2 + 6x + 5): factor out 2
2(x + 5)(x + 1)
After factoring out the 2, find the 2 numbers that multiply to get 5 and add to 6
5 + 1 = 6
5*1 = 5
x^2 = x * x
11. (x - 10)(x - 4)
12. (a - 8b)(a + 8b)
a^2 + 8ab - 8ab - 64b^2
First: a*a = a^2
Outside 8b*a = 8ab
Inside: -8b*a = -8ab
Last: -8b*8b= -64b^2

Round 0.043 to the nearest hundred
Answer:
0.04
Step-by-step explanation:
Find the number in the hundredth place, in this case its 4
and look one place to the right for the rounding digit, in this case its 3
Round up if this number is greater than or equal to 5 , and round down if it is less than 5.
Answer:
0.04
Step-by-step explanation:
I was taught "5 or more, let it soar, 4 or less, let it rest" Since the number next to the hundreths place is 3, the 4 stays the same.

In 2016 the average NBA ticket for the final was $1444. In 2017 the price increased by 20%. If this trend continues what will the price in 2020?
Answer:
roughly 3593.13
Step-by-step explanation:
1444 x 0.2
288.8
1444+288.8 = 1732.8
1732.8 x 0.2
346.56
1732.8 + 346.56 = 2079.36
2079.36 x 0.2
415.87
2079.36 + 415.87 = 2495.23
2495.23 x 0.2
499.05
2495.23 + 499.05 = 2994.28
2994.28 x 0.2
598.85
2994.28 + 598.85 = 3593.13

Suppose that a box of 86 circuits is sent to a manufacturing plant. Of the 86 circuits shipped, 5 are defective. The plant manager receiving the circuits randomly selects 2, without replacement, and tests them. If both circuits work, the manager will accept the shipment. Otherwise the shipment is rejected. What is the probability that the shipment is accepted
Answer:
the probability that the shipment is accepted is 0.8865
Step-by-step explanation:
Given the data in the question;
N = 86, n/d = 5 and n = 2
now, without replacement
the probability that the shipment is accepted will be;
probability that the shipment is accepted = probability that non is defectives
so p( non is defective ) = ( (86-5)/86) × ((86-5-1)/(86-1))
p( non is defective ) = ( 81 / 86) × (80/85)
p( non is defective ) = 0.8865
Therefore, the probability that the shipment is accepted is 0.8865
