Jessie installed 12 more axles than the number of engine blocks her friend Gus installed yesterday. Write an equation for g, the

jeka94

Answer:

g = j - 12

Step-by-step explanation:

Let's say Jessie installed j axles. Convert words to math:

- "12 more" = + 12

- "the number of engine blocks her friend Gus installed yesterday" = g

Put it together: g + 12. This is equal to j: j = g + 12. Solve for g:

j = g + 12

g = j - 12

.) A population of values has a normal distribution with μ=27.5 and σ=71.5. You intend to draw a random sample of size n=180.

Paraphin [41]

Answer: a) 27.5, b) 5.33.

Step-by-step explanation:

Since we have given that

$\mu =27.5\\\\\sigma =71.5$

and n = 180

We need to calculate the sample mean and sample standard deviation.

So, the mean of the distribution of sample means is

$\mu = \mu_x=27.5$

The standard deviation of the distribution of sample means is

$s=\dfrac{\sigma}{\sqrt{n}}=\dfrac{71.5}{\sqrt{180}}=5.329=5.33$

Hence, a) 27.5, b) 5.33.

The triangular numbers are defined by the recursive formula t1 = 1, tn = tn - 1 + n, where n ∈N and n > 1. What are the first

GalinKa [24]

ANSWER

C) 1, 3, 6, 10, 15, 21, 28, 36, 45

EXPLANATION

The recursive formula is,

$t_1=1,t_n=t_{n-1}+n$

when n is a natural number greater than 1.

When n=2,

$t_2=t_{2-1}+2$

$t_2=t_{1}+2 = 1 + 2 = 3$

when n=3,

$t_3=t_{2}+2 = 3 + 3= 6$

when t=4,

$t_4=t_{3}+2 = 6+ 4= 10$

When t=5,

$t_5=t_{4}+5 = 10 + 5 = 15$

when t=6,.

$t_6=t_{5}+6 = 15 + 6 = 21$

when t=7

$t_7=t_{6}+7 = 21 + 7 = 28$

When t=8,

$t_8=t_{7}+8 = 28 + 8 = 36$

When t=9,

$t_9=t_{8}+9 = 36 + 9 = 45$

Hence the first nine triangular number are

C) 1, 3, 6, 10, 15, 21, 28, 36, 45

(w-x)^2 + 26x; if w = 6 and x = -1

kati45 [8]

Answer:

$\boxed{\boxed{\sf 23}}$

Step-by-step explanation:

$\boxed{\sf Hi\: there!}$

$\sf (w-x)^2 + 26x$

$\sf w=6$

$\sf x=-1$

_____________________

→ $\sf \left(6-\left(-1\right)\right)^2+26\left(-1\right)$

→ $\sf 23$
