The cost is $395. You are trying to find <em>n</em> in 24<em>n</em> + 35.
Set C = 395.
You get 395 = 24<em>n</em> + 35.
Solve for <em>n</em> by first subtracting 35 from both sides of the equation:
395 - 35 = 360.
24<em>n</em> + 35 - 35 = 24<em>n</em>.
Now you have 360 = 24<em>n</em>. Divide both sides by 24 to get:
15 = <em>n</em>.
So, 15 birthday cakes are made when the cost is $395.
It’s 1 and I’m just type cuz it don’t lemme answer
Answer:
Choice A: there is insufficient evidence to conclude that the mean for the fiber content is less than 2.5 gms.
Step-by-step explanation:
From the graphs given the more appropriate is one sample t- test
One sample t- test is used and the results are
Hypothesis Test Fiber
Sample Mean 2.62
Sample St. Dev 3.492
Degrees of Freedom 24
t- test statistic 0.1718
p- value 0.5675
the critical region for this test at ∝= 0.05 is t < -1.711
There is not enough evidence to reject the null hypothesis.
Since the calculated t= 0.1718 does not fall in the critical region the null hypothesis is accepted that the mean fiber content is not less than 2.5 grams.T

Answer:
a = 7.2
Step-by-step explanation:
The figure has been re-labelled and attached to this response.
From the figure, the larger right triangle DAB and the small right triangle BCA are similar. This is because;
i. They have two corresponding congruent angles which are<em> the right angle</em>
and <em>angle B</em>
Therefore, we can say that;
<em>Cross multiply</em>
a x a = 13 x 4
a² = 52
a = √52
a = 7.2
Note: The figure showing the similar triangles has also been attached to this response.
